FLUID ELECTRICAL CONDUCTIVITY

Fluid Electrical Conductivity Reference:
Process fluid to have a minimum of 10uS/cm of conductivity. Recommend 50 uS/cm or higher. Use of non-conductive fluids prohibited.
The basic unit of fluid conductivity is “mho/cm”, otherwise known as 1 Siemen. However, this unit does not really occur in water, so we typically use one thousandth (mili-) or one millionths (micro-) of it for natural waters (1000 milimhos and 1,000,000 micromhos are equal to one mho).
The useful unit for seawater is milimhos/cm (mS/cm); seawater is around 55 mS/cm.

The useful unit for freshwater is micromhos/cm (μmhos/cm, or μS/cm); tap water ranges between 50 and 800 μS/ cm (depending on the source).

NOTE: This table of fluid conductivity is for reference only, to show the relative conductivity of various fluids. Since the list contains flammable fluids, it is not to be construed as a list of permissible fluids to be used with QSE series meters.
NOTE: QSE series meters are for use with water, aqueous solutions and other nonflammable, electrically conductive fluids. Do not use the meter with petroleum products (diesel fuel, unleaded gasoline, jet fuel, kerosene, etc.) or other incompatible chemicals.

METER OVERVIEW

Introduction
The QSE meter has multiple types of output electronics available. The electronics for the operation of the meter coils and flow tube are housed within the meter body casing.
The cover plate is designed in two versions; a plain cover plate or a display mount cover plate. The electronics (QB) and the choice of communications suites (QSI1, QSI2 or QSI3) are housed within the plain cover plate. A display (Q9) is also available mounted to the “display mount” cover plate.

All meters are equipped with galvanically isolated pulse-out electronics (QB) as the default standard, regardless of style of cover plate.
This manual contains overall information related only to the meter. This meter is externally powered and all external wiring connects to the electronics within the cover plate through its threaded ports.
The magnetic coils, electrodes and other electronic components within the main meter body receive power from the electronics housed within the cover plate through a ribbon
cable. See the included electronics manuals for meter wiring diagrams specific to your meter electronics.

Important Notice
Your QSE meter is supplied ready for operation in a wide variety of applications. The meter has been factory configured to your order. It is suitable for volumetric flow measurement of non-flammable, electrically conductive liquids that have a minimum fluid conductivity of 10 μS/cm, and are compatible with the wetted components of the meter (See Specifications section).

Fluid conductivity below 50 μS/cm may result in uncertain readings. Consult factory for use with fluids having a conductivity below 50 μS/cm.
Use QSE series meters with water, aqueous solutions and other non- flammable,electrically conductive fluids. A fluid conductivity chart of common liquids is in this manual for your reference. Do not use the meter with petroleum products (diesel fuel,unleaded gasoline, jet fuel, kerosene, etc.) or incompatible chemicals.
QSE series meters are very sensitive to electric noise if operated within 6 inches (15.2cm) of some electric motors, relays, transformers or other sources of electronic noise.

If the QSE series meters are used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Principle of Operation
Faraday’s Law of Electromagnetic Induction is the operating principle on which the QSE series meters are based. Faraday’s Law (paraphrased) states that a voltage will be induced in a conductor when it passes through a magnetic field, and the induced voltage will be directly proportional to the velocity of the conductor passing through that magnetic field. In this case, flowing liquid is the conductor and the QSE meter creates the magnetic field.
The velocity of the flowing liquid, which must pass through the magnetic field, is the velocity of the conductor. A voltage is induced in the conductive liquid as it passes through the magnetic field. By placing electrodes in calculated locations on the flow tube of the meter, it is possible to accurately measure the induced voltage, thus determining the corresponding velocity and volumetric flow of the liquid.

Safety

• This product is not approved for use with petroleum products (diesel fuel, unleaded gasoline, jet fuel, kerosene, etc.), aromatic hydrocarbons, flammable fluids or other incompatible chemicals
• This product is not approved for use in hazardous locations.
• Be sure O-rings and seals are kept in good repair.
• When applying power, adhere to specifications listed in appropriate electronicsmanual.
• Disconnect external power before attaching or detaching input or output wir es.

INSTALLATION

Earth Ground
When making installations, the magnetic flow meter grounding rules have to be observed. The sensors of the QSE flow meter are sensitive to any electrical noise that is always present in piping systems. The fluid in piping systems usually carries significant levels of static electricity, and should be grounded for the QSE meter to be at its best performance.

As part of the installation, it is important to understand the importance of having the QSE meter connected to “earth ground”. Earth grounding helps ensure electronic component stability and reliability by using the earth to absorb any static charge buildup or spurious signal noise that can affect the meter electronics. Earth ground in this installation is NOT the ground wire in the customer isolated power supply.

Process Fluid Grounding
Establishing a process fluid ground is one of the most important installation details.
Proper process fluid grounding ensures that the sensor and fluid are at the same electrical potential so that only the induced flow signal is measured. The process fluid grounding provides a stable base potential reference for measuring the induced flow signal (the differential between the base potential reference and the fluid flow potential created by the sensor magnetic field). Process fluid grounding should be established on both sides (upstream and downstream) of the sensor elements.

By connecting the QSE sensor, the fluid, and the reference used by the internal electronics to a stable, noise free reference point (earth ground), the user is ensured of getting the best performance from their magnetic flowmeter.
Each QSE meter has a ground lug with a removable ring terminal located in the circular wall adjacent to the outlet end of the meter. This ground lug is connected internally to the electronics and sensors and is the meter connection to earth ground (the base potential reference).

Grounding Summary

1. Ground sensor to meter ground lug. (Done at factory.)
2. Ground electronics to meter ground lug. (Done at factory.)
3. Ground process fluid to meter ground lug (customer responsibility). Variousprocess fluid grounding examples are shown on the following pages (see Figures 1, 2, and 3) to assist you in completing this item. The examples cove rvarious meter installation situations.
4. Ground the meter ground lug to earth ground (customer responsibility).
   All of the examples on the following pages show 14-16 AWG ground wire (customer supplied) being used. A ground wire should be crimped to the ring terminal on the meterground lug and the other end of the ground wire connected to earth ground (item 4  above).

GROUNDING – ANSI Flange – Non-Conductive (Plastic) Pipe
Using Commercially Available Grounding Rings

METAL PIPE – ANSI FLANGE – Flexible Expansion Joint

CAUTION: When installing to metal pipe, it is recommended to use flexible expansion joints on one or both ends to eliminate any stresses that might be incurredfrom misaligned rigid metal piping. Failure to do so could result in permanent  meter damage.

NOTE: Flexible expansion joints on both sides of the meter are recommended, however, some applications may only require a single flexible expansion joint to be used.
GPI is not responsible for any damage that may occur when installing a QSE Meter in metal pipe applications, regardless of the use of a single or both flexible expansion joints.
Figure 3A

Connections
Install your meter in-line with either horizontal flow or vertical flow. The best meter position for horizontal flow setups is with the meter rotated slightly (about 1 o’clock or 2 o’clock) to tilt the top from the horizontal plane (see Figure 4). This prevents sediment from settling on the lower set of sensing electrodes. Install the meter with the flow arrow pointing in the direction of fluid flow.
Plan to install meter with minimum straight pipe lengths at inlet and outlet ends. The straight run lengths noted below represent the minimum requirements for accurate flow measurement (see Figure 4). For optimum performance, provide as much additional straight run as possible.

• Upstream from the meter, allow a minimum straight pipe length of (5) times the pipe diameter from bends and obstructions.
• Downstream from the turbine, allow a minimum straight pipe length of (3) times the pipe diameter from bends and obstructions.
• Avoid downward flow that can lead to partially filled pipes

NPT Fittings
Seal all pipe threads with an appropriate non-lubricated thread sealant (such as Loctite® No More Leaks™ Plastic Pipe Thread Sealant or NSF equivalent for NSF applications).
Make sure the thread sealant does not intrude into the flow path. Hand tighten the meter at the housing ends. Do not use a wrench or similar tool to tighten as this can damage the housing.

NOTE: If connecting to new female pipe threads, burrs and curls can adversely affect accuracy. Correct the problem prior to meter installation.

BSPP Fittings
The BSPP meter includes a plastic bag containing (2) O-rings and (2) backup rings that must be installed onto the meter. They are used for sealing the fitting ends of the meter to process piping. Before installing the meter, install an O-ring in the O-ring gland on each housing end, then fit a backup ring over each O-ring (see Figure 5).
The BSPP meter is now ready for installation. Hand tighten the meter at the housing ends. DO NOT use a wrench or similar tool to tighten as this can damage the housing.

ANSI Flange Fittings
The flanges supplied with your meter allow the meter to be oriented regardless of the mating flanges position. The meter flanges and their steel half-ring “keys” must be installed onto the meter by the customer before meter installation (see Figure 6).

Installing Flanges on Meter
With the mating face of the flange facing outboard, slide flange over one end of the meter. Position (2) half-rings in the retaining groove and snap into place. Each end of a half-ring has a small lobe that snaps into a recess at the top and bottom of the groove for retention. Repeat at other end.

Customer to Provide:

• Ring Gaskets or Full-Face Gaskets approved for use with type flange installed and the fluid being monitored (2 required).
• 5/8 in. bolts and nuts for ANSI flanges. Four per side for 3-inch meters; eight per side for 4-inch meters.
• Torque bolts using a star pattern to 25 ft-lbs (33.9 N•m). For best results, alwaysverify torque accuracy before use.

NOTE: Do not over tighten the flange bolts. This may cause the gasket to be  compressed into the flow stream and may decrease the accuracy of the meter.
When properly installed, the flow meter will only measure flow in that portion of the piping system where the meter is installed. Choose the location with the longest straightunobstructed run of pipe, keeping in mind that in some applications it may be possible  to locate the meter in either the supply or return pipe.

NOTE: Each end of the flow tube has a boss on top with a recessed floor. Meters ordered with optional temperature sensing probes have a 1/8-27 NPT port tapped intothe floor for factory installation of the probes. The ports can also be used to install a FLOMEC Grounding Probe Kit if the temperature sensing probes are removed.
Meters ordered without temperature sensing probes do not have  tapped ports in the boss floor. To install a FLOMEC Grounding Probe Kit in these meters, the customermust drill and tap the ports per the Grounding Probe Kit instructions.

WARNING: Compatibility of this product’s material and the process fluid and/or environment should be considered prior to putting into service.

WARNING: Product should never be operated outside its published specifications for temperature or pressure. See specifications for your model.

WARNING: Make sure flow and pressure have been eliminated from process pipe prior to installing or removing product.

WARNING: When connecting product to process piping: For NPT fittings use nonlubricated thread sealant (such as Loctite® No More Leaks™ Plastic Pipe Thread Sealant or NSF equivalent for NSF applications). For BSPP fittings use O-ring seals. For flange fittings use flange gaskets.

CAUTION: Installation near high electromagnetic fields and high current fields is not recommended and may result in inaccurate readings.

• Do not allow water to freeze in meter. Ice expansion may burst the plastic housing.
• Do not allow this meter to be used with steam.
• Piping should be properly supported to prevent undue structural stress on the meter body.
• Pipe misalignment can cause strain on meter bodies resulting in permanent damage.
• When installing to metal pipe, it is recommended to use flexible expansion joints on one or both ends to eliminate any stresses that might be incurredfrom misaligned rigid metal piping. Failure to do so could result in permanent meter damage.

Wiring

All electronic options are associated with a matching style of meter cover plate. This cover plate has four threaded ports, compatible with PG7 threads, for gaining wiring access to the electronics inside the cover plate. The meter is shipped with the ports environmentally sealed with a threaded plug and seal. Remove one or more of these plugs as required to install the supplied port fittings below.

Each meter is supplied with cable gland strain reliefs with O-rings and 1/2 NPT adapters with seals for use in the threaded ports of the meter cover plate. Select the port fittings that fit your process and replace the threaded plugs in the cover plate with the fittings as required. The threaded plugs installed at the factory may be left in any unused cover plate port indefinitely.

It is recommended that a “removable” thread-locker (fluid, stick, tape, spray, etc.) be used when installing the strain reliefs or adapters into the cover plate ports.

Strain Reliefs:
The cable gland strain reliefs will accommodate a cable diameter of 0.11 – 0.26 inches (2.79 – 6.6mm) and provide an environmental seal around the cable when the dome-nut is tightened.

NPT Adapters:
The 1/2 NPT adapter fittings are used for attaching flex conduit to the meter, for those applications that require cable runs to be enclosed in conduit.

• Cable to be provided by customer to accommodate job requirements. Cable is not included with meter.
• This meter is externally powered. The magnetic coils, electrodes and other electronic components within the main meter body receive power from the electronics housed within the cover plate. All external wiring connects to those cover plate electronics through threaded ports. See the included electronics manuals for meter wiring diagrams specific to this meters electronics.
