1 General Information

Thank you for choosing a Rheonik Coriolis Flow Meter. Each meter is designed to give many years of service in one of a wide variety of applications across many industries. Prior to delivery, the meter was carefully calibrated, and the entire sensor subjected to an overpressure test at 1.5 times the maximum operating pressure limit. Manufacturing records are meticulously maintained for each sensor to assist in any future support request received.

This manual is one of several available packed with valuable information on how to get the best performance out of your Rheonik flow meter. If you cannot find an answer in the manual set to any question you might have related to start up, operation or support of this product, please contact your local sales/support agent or Rheonik Support for immediate assistance.

1.1 Intended use
**** Rheonik Coriolis mass flow measuring instruments consisting of a sensor (RHM), a transmitter (RHE), and in some cases, an interconnecting cable, are intended for measuring liquids and gases.

The operator must ensure that the instrument is only used in a way that complies with limitations and certifications listed on the instrument type plates. These limitations/certifications include, but are not limited to:

• Pressure and temperature ranges
• Approval limits (e.g., explosion protection, pressure equipment directive)
• Suitability of the materials of construction in contact with the process

The instrument must be installed, operated, and maintained in accordance with the manufacturer’s instructions and guidelines.
The instrument must not be modified or altered in any way that has not been approved by the manufacturer or certification body.
Regular inspections and preventive maintenance should be carried out to ensure ongoing safety and performance.
Use not in accordance with the intended purpose may impair and/or endanger safety.

1.2 Important Instructions and Safety Information for Operating Coriolis Flow Meters
**** Rheonik flowmeters are made for a wide variety of applications and in compliance with many international standards. Maximum operating limits (temperature, pressure) for each RHM flow sensor are stated on the permanently attached serial number plate and must not be exceeded.

Where flowmeters are operated at elevated temperatures, thermal insulation around the sensor should be provided to ensure that the entire flowmeter is kept at or very near the operating temperature of the process.

When using flow meters in or near piston pump outlets, ensure pressure peaks in the process line do not exceed the flow sensor maximum pressure limit.

Meters installed in any process with an abrasive fluid may be subject to internal wear with a subsequent reduction of tubing wall thickness. This abrasion may reduce the safe maximum operating pressure of the meter. In applications where internal wear is a possibility, we recommend instigating an NDT program to monitor the meter condition. Please contact Rheonik for assistance with determining a procedure for such a program.

The process wetted material(s) within the flow meter are stated on each meters’ serial number plate. It is the sole responsibility of the end user to ensure that these material(s) are suitable for use with the process the meter is applied to. In applications where internal corrosion is a possibility, we recommend instigating an NDT program to monitor the meter condition. Please contact Rheonik for assistance with determining a procedure for such a program.

Flow meters installed in processes in the pharmaceutical or food and beverage industries should, where appropriate, be fully cleaned before being put into service.

Caution, the surface of a meter may be hot.

2 Introduction to Rheonik Coriolis Flow Meters

A complete flowmeter system typically consists of a:

• RHMxxx Sensor
• RHExx Transmitter
• Interconnection cable

2.1 RHMxxx Sensor
Inside an RHM sensor, there are precision tubes energized by an electromagnetic drive system controlled by the attached RHExx transmitter. These tubes vibrate at their natural frequency.

When a fluid (liquid or gas) flows through these vibrating tubes, they are subjected to non-symmetrical deflection, the degree of which is determined by the mass of the fluid passing through. This deflection is detected electronically by two sensors within the flow meter body. High-precision electronics in the transmitter process the sensor signals and calculate a time delta between them. This time delta is proportional to the mass flow rate.

RHMxxx sensors are intrinsically safe and can be certified for use in hazardous areas when connected to a suitably certified transmitter.

Standard flow meter dimensional information can be found in each of the RHMxxx data sheets. Data sheets or exact drawings for customized products can be obtained through your local sales/support agent or from Rheonik.

2.2 RHExx Transmitter
The transmitter provides the drive energy for maintaining tube vibration within the sensor, processes and evaluates of the measured signals and calculates mass flow along with other parameters.
When used with an RHMxxx sensor in a hazardous area, the RHE is equipped with the necessary safety barriers as required by local regulations.
A detailed description of transmitter features is available in each of the RHExx data sheets.

3 Mechanical Installation

Proper meter performance depends upon good installation. This chapter details best practices for installing a meter in different types of applications.

3.1 Storage, Handling and Transportation
Upon receipt of a meter shipment:

• Inspect the package thoroughly for damage. If there is evidence of damage, please notify the carrier and your local sales/support agent immediately.
• Review the packing list and check that all ordered components have been received.
• Check the serial number plate(s) to ensure that the components delivered are according to the purchase order.

3.1.1 Lifting

Heavy sensors require additional consideration when lifting them into their installation position:

• Professional equipment for handling heavy sensors should be used.
• Lift sensors as shown in Figure 1.
• Do not lift a sensor by its electrical junction box or purge fittings.

Figure 1: Lifting a heavy meter

After the sensor has been removed from its packaging, check to ensure that all accessories and documentation have also been removed. The packaging should be kept and stored for possible future shipment. Flow meters should be stored in the following conditions:

• Store in a dry and dust-free location.
• Avoid direct exposure to solar radiation.
• Store in original packing.
• Store in temperatures between -20°C and +70°C.

3.2 Filters and Strainers
For liquid measurement applications that have solid particles with a diameter of 0.25 times the inside diameter for the measuring tubes, a filter/strainer must be installed upstream from the flow meter to reduce the risk of blockage.
A filter must be installed for gas measurement applications with abrasive particles in the stream (e.g. rust particles) in order to avoid damage (abrasion) to internal measurement tubes.

3.3 Temperature
Do not install the meter in an application that will exceed its maximum temperature rating (see serial number plate for temperature limit). The flow meter should be installed such that it is kept at the same temperature while in operation.

**** Rapid temperature changes should be avoided whenever possible. Rapid temperature changes may impact the performance and lifetime of the sensor.
Temperature change to a sensor should be at a rate of no more than 1°C per second.
Temperature changes while in operation should be minimized by the use of insulation and/or heat tracing where applicable.

3.4 Zeroing Procedure and Isolation Valves
Like all Coriolis instruments, the meter may require zeroing from time to time to remove any offset in the measured flow rate.
Zeroing of the meter should be carried out:

• When an RHM flow sensor and/or RHE transmitter has been newly installed.
• Before field or laboratory calibration of the meter.
• During routine maintenance of the meter.

Please refer to the RHE Installation and Startup Guide for zeroing instructions.

For the best measurement performance, the meter should be zeroed under full operating pressure and temperature. A shut off valve should be installed downstream of the meter to facilitate zeroing. It is highly recommended to install a valve upstream of the meter as well to prevent convection flow that might affect the zeroing procedure. Only tight-closing, high-quality valves should be used. In the majority of cases, relying upon simply switching off a pump will not be sufficient.

Figure 2 shows the recommended installation of an RHM sensor with valves to facilitate meter zeroing.

Figure 2: Zeroing with closed valves

3.5 Upstream/Downstream Straight Run Requirements
No upstream/downstream straight run is required for sensor models RHM015 – RHM20 with a manifold or serial (single path) seal-less construction type. .For seal-less, parallel construction type sensors, straight pipe sections of 5-10 pipe diameters upstream and 3-4 pipe diameters downstream should be provided where flow is connected to the meter out of plane with the sensor meter tubes. This is required to avoid different flow velocities being established within the two measuring tubes.
No valves or reducers should be installed between the pipe mounting supports and the sensor.

3.6 Accessibility
For accessibility during mounting and maintenance, clearance of at least 10 cm (4”) from the RHM sensor is recommended in every direction.

3.7 Vibration
Vibrations can impair the functionality and measurement accuracy of the RHM sensor. Please take into account following:

• The pipe system must be as free as possible from all vibrations. In principle, standard building or system vibrations have no significant impact on the accuracy of the measurement. Nevertheless, heavy vibrations should be avoided at all costs.
• It is recommended that you install the flow meter at a point that vibrates as little as possible. Use solid pipe clamps onto a rigid, non-vibrating surface to decouple the meter from pipe and other vibrations.
• Isolation from mechanical vibrations can also be achieved by using flexible tubes between the sensor and the fixed piping system. Other methods, such as installing the sensor after a bend can also be employed to minimize vibration issues.
• Any unsecured pipe sections situated near the flow meter that might have a tendency to vibrate should definitely be avoided.
• Both the mechanical design of the flow meter and the implementation of digital filtering in the transmitter signal processing electronics will minimize the effects of vibration on the measurement. However, please note that excessive external vibration can impact measurement performance and, under certain circumstances, cause damage to the flow meter.

3.8 Cross Talk
If two or more RHM mass flow sensors are located close to each other, cross talk may occur between them and measurement precision may be degraded, particularly at low mass flow rates. Sensors should be installed with sufficient spacing to prevent cross talk between them.

3.9 Magnetic Interference
RHM flow sensors must not be installed in environments with strong magnetic fields as these can severely disturb the measurement. Ensure that sensors are installed a sufficient distance from motors, turbo machines, large transformers, electrically operated valves, power contractors etc. to prevent any impact on measurement performance.

3.10 Pipe Alignment
Process connections must meet the sensor face to face length and should be properly aligned. Misaligned pipe connections may exert abnormal forces onto the flow sensor, potentially impacting measurement performance and possibly damage.

3.11 Flow Direction
RHM flow sensors are bi-directional.
If, once the flow meter has been mounted, the flow reading is opposite or negative to the flow reading expected, the flow sense can be corrected by parameter adjustment in the transmitter. Please refer to the RHE transmitter manual for instructions.

3.12 Horizontal Pipe Mounting
The location and orientation of a sensor in line is application dependent although whenever possible, installation of an RHM sensor is preferred in a horizontal pipeline.

• Liquid applications: For liquid measurements, the RHM sensor should be installed at a low point in the pipe system with its measurement tubes pointing downwards as this will prevent gas bubbles collecting in the sensor. The presence of gas bubbles can reduce the performance of the sensor for both mass flow and density. See the recommended orientation in Figure 3 (A).
• Liquid applications with solid particles in the fluid: If there is a risk that the liquid contains (heavy) solid particles, the RHM sensor should be installed at a high point in the pipe system with its measuring loops pointing upwards to avoid the collection of the particles in the sensor. See the recommended orientation in Figure 3 (B).
• Gas applications: For gas measurements, the RHM sensor should be installed at a high point in the pipe system with its measuring loops pointing upwards to avoid condensation or other liquids collecting in the sensor. See the recommended orientation in Figure 3 (B).

Figure 3: Installation positions for liquid (A) and liquid applications with solid particles/gas applications (B).

It is recommended to install RHM flow sensors with rigid supports at both the inlet and outlet. The supports should be placed apart at a distance of no more than three times the width of the sensor housing.

A range of mounting brackets are available for smaller meters and are highly recommended.

Figure 4: Wall mount bracket (A), floor mount bracket for liquids (B) and floor mount bracket for gas application (C)

Robust supports are needed for large, heavy sensors in order to protect the mechanical integrity of the pipe.
Avoid heavy shocks to the RHM flow meter at any time.

3.13 Vertical Pipe Installation
Installation of an RHM sensor in a vertical pipe (“flag” installation) is only recommended for pure liquids without gas and solid particles and for dry, non- condensing gases. Due to the internal arrangement of the tubes within the meter, there is the possibility that for low flow liquid installations, gas bubbles and/or solids may accumulate in the meter. For low flow gas installations there is a possibility that some liquids may accumulate in the meter.

For liquid applications with possible gas content, flow should be upwards through the meter to assist in purging and removing accumulated gas from the meter.

Liquid applications with possible content of solid particles should be avoided.

For gas installations the flow should always be downwards through the meter.

When putting the meter into service, it is important to ensure that it is completely filled. To achieve this, a relatively high flow should be introduced to the meter to purge unwanted liquid or gas.

Figure 5 shows the recommended orientation for the flag installation. Notice the two firm supports either side of the meter on the inlet and outlet piping.

3.14 Critical Installations
Figure 6 shows three critical installations.
For an RHM sensor in a liquid application installed in flag position at (A), the pipe should not be open ended below to avoid the RHM sensor running dry.
If solids are expected in a liquid application, or wet gas is being measured, installation at the deepest point of the pipework (B) should be avoided.
If gas bubbles are expected in a liquid application, installation at the highest point of the pipework (C) should be avoided.

3.1 Liquids with low Vapor Pressure
Where a liquid with low vapor pressure is being measured, the system pressure throughout the flow meter must be maintained above the vapor pressure, otherwise cavitation or flashing may occur. Flashing/cavitation can severely impair the performance of the meter. Attention should be paid to other pipeline components (such as valves etc.) upstream of the meter that can also cause cavitation/flashing and affect meter performance. If necessary, a pressure regulator should be installed downstream from the sensor to ensure pressure in the line is maintained above the fluid vapor pressure and therefore, prevent cavitation from occurring. Generally, it is recommended to have backpressure downstream of the flow sensor.

4 Electrical Connection to RHE

The RHM sensors are designed for simplest connection to and best operation with all RHE transmitters.
The electrical connection type of the RHM sensor is included in the RHM product and ordering code, please see section 6 for further information.
For the electrical connection to the RHE transmitter please refer to the respective RHE Installation & Startup Guide.

Caution, the surface of the connection box may be hot if a hot fluid is running through the RHM sensor.

5 Service and Maintenance

5.1 Maintenance and Calibration
RHM flow sensors and their associated RHE transmitter do not require any regular maintenance.
Under normal circumstances, RHM flow sensors and their associated RHE transmitter should not require flow calibration. If flow calibration is required, either as a one off check or at prescribed intervals to meet statutory or operational requirements, it can be carried out in one of two ways:

1. In the field against a certified reference meter or prover
2. At a calibration laboratory

Local regulations or contractual/operational requirements will determine the method and interval of such calibrations. Refer to the RHE transmitter manual for full details on calibrating flow meters.

Regular checks of the zero point calibration are recommended to ensure consistent measurement accuracy and performance.
Density measurement can be calibrated in the field. Please refer to the RHE transmitter manual for instructions.

5.2 Troubleshooting
If an RHE transmitter, correctly connected to an RHM flow sensor, displays an error message related to the sensor, the sensor can be checked as follows:

1. With the sensor connected to the RHE flow transmitter, check voltages at the RHM flow sensor terminals using a good quality voltmeter/multimeter. Voltages should be within the ranges given in Table 1.

Table 1: Sensor voltages

2. With the sensor disconnected from the RHE flow transmitter, check internal sensor resistances at the RHM flow sensor terminals using a good quality ohmmeter/multimeter.
Resistances should be within the ranges given in Table 2 or 3.

Table 2: Sensor resistances- option 1

If both measured voltage and resistance values do not fall within stated ranges, the RHM flow sensor is defective. If a voltage value only is out of range, the fault may be in the RHE transmitter.
In either event, please contact your local sales/support agent or Rheonik Support for assistance.

5.3 Service
RHM flow sensors do not contain any user serviceable parts. Please contact your local
sales/support agent or Rheonik Support for assistance.

5.4 WEEE and RoHS
RHM flow sensors are not subject to the WEEE directive.
RHM flow sensors are fully compliant to the RoHS directive.

A.3 Electrical Safety Limits
Intrinsically safe RHM:

*) With hazardous areas approval code “AB” or “CB”: Li = 6.7mH

Notes:
If the letter plate of the RHM specify different values, the values on the letter plate are to be observed!
The values for Li and Ci include the influence of the cable for connection types “T*” (fixed cable).
Only transmitters with linear barriers with negligible Li and Ci values may be used. All approved
Rheonik transmitters RHE* comply with this requirement.
The terminal numbers are the numbers in the connection boxes (connection type J, S).
For the cable colors for connection type “T” (fixed cable) refer to the drawings in chapter A.6.
RHM with temperature ranges above 210°C (temperature code H*) and below -50°C (e.g. temperature code E3) must only be operated with certified transmitters by Rheonik with grounded circuits.
Between RHM and transmitter potential equalization must exist.

Non-sparking RHM:
The RHM must only be connected to any transmitter RHE by Rheonik.

A.4 Thermal Safety Limits
Note:
Some temperature ranges specify narrower temperature ranges than the maximum ranges indicated below. The range E3 for example is specified for -196°C to +50°C. In that case the limits on the letter plate must be observed.

For all temperature ranges the body of the RHM may be completely isolated for reducing the heat transfer between ambient and fluid, as long as the connection box remains outside the insulation.

The temperature of the connection box must not be less than -50°C or more than +105°C.
The connection cables ARHE-C4 and ARHE-C6 are specified for -50°C to +105°C. They can be used at temperatures below -50°C, if they are fed in a rigid tube.
With RHM*** type TM (fixed Teflon cable) the cable withstands -196°C to +205°C.

**Temperature Ranges N**
The mass flow sensors with temperature ranges N cover different temperature ranges in the total range from -50°C to +120°C.

**Temperature Ranges E**
The mass flow sensors with temperature ranges E cover different temperature ranges in the total range from -196°C to +210°C.

*) At ambient temperature below -40°C the minimum flow temperature rises linearly from -196°C at -40°C ambient temperature to -50°C at -50°C ambient temperature, see graph below.

Derating of minimum fluid/gas temperature for low ambient temperatures.

**Temperature Ranges H**
The mass flow sensors with temperature ranges H cover different temperature ranges in the total range from -20°C to +400°C.
The optimum operation temperature is 100°C to 400°C. For permanent operation temperatures below 100°C we recommend the use of sensors with a temperature range N or E.

A.5 Grounding
IEC60079-0 recommends to ground shielded cables just on one end, normally outside the hazardous area. On the other side the shield may be grounded via a 1nF capacitor.

In small installations (cable length typically less than 10m) the shield can be grounded on both sides, provided that there is no potential difference between PE at the RHM and PE at the RHE.

This can be assumed if there is a good metallic contact or if a dedicated PE cable of at least 4mm² connects the two grounding points.

With the connection versions J and S terminal 10 (PE) is connected directly to case and terminal 11 (PE_C) is connected to the case via a 1nF / 1000V capacitor. The shield can and should be connected directly to one of these terminals, depending on the guidelines mentioned above.

With the connection versions T* the shield is connected to the housing of the RHM. As the standard cable length is 2m, the shield normally can be connected to the PE terminal of the RHE.

If this is not allowed due to local restrictions, use a 1nF /1000V in series.

A.6 Electrical connection to RHE

Electrical connections between RHM** connection type S, J* (connection box) and a RHE20.

Electrical connections between RHM** connection type T (fixed cable) and a RHE20.

A.7 Ordering Code
The following extract of the ordering code shows the information relevant for hazardous areas.
MaaaTTPPCCCMMFFCC-OO-EE (may be followed by codes for additional options)

Not all combinations are possible. For available combinations see instructions.

The temperature class of the marking depends on the meter type, refer to the label on the meter.

Where no versions for the place holders are specified, these parameters are not relevant for the Ex certification. Where versions are specified (e. g. for “cc connection type”: SM, TM etc.), versions not listed here are not available with Ex certification.

The asterisk * is a placeholder for special custom specific versions within the specified range. Regarding the electrical and thermal limits of special versions refer to the letter plate of the unit.
