Introduction

The FMA1000 series industrial air velocity/temperature transmitter/indicator measures and displays air velocity mass flow and air temperature of clean air flows in ducts & pipes, while producing very little pressure drop in the flow stream. The FMA1000 series can be used in research & development labs, HVAC applications, and other manufacturing processes. The sensor design is based on three RTD elements, one measures the air temperature and the other two measure the air velocity. The air velocity is measured based on the heat loss from the RTD velocity sensor as it cools down by the air flow. The FMA1000 series offers many standard features such as dual display of
air velocity & temperature, two analog outputs corresponding to air velocity & temperature, high & low voltage alarm outputs for air velocity, USB PC interface with a Windows based PC interface software. The FMA1000 displays the air velocity in feet per minute (FPM), meter per second (m/s), miles per hour (MPH), and kilometer per hour (Km/h). The air temperature is displayed in ºF & ºC. The sensor probe is 12″ long as standard. The 304 Stainless steel sensor tubing is provided with inch marks for ease of insertion depths. The sensor probe comes in four different versions as follow

• Fixed probe mount
• Right angle probe mount
• Remote probe
• Fixed short probe, 3.75 Long

Important Considerations Before Installation

The FMA1000 air velocity transmitter is not explosion proof, nor is it Intrinsically safe. Do not use for flammable or hazardous gases, or in Hazardous areas. The FMA1000 series air velocity transmitter is intended for use with clean air or Nitrogen ONLY. Do not use with other gases, as it will produce an un-calibrated and non linear display measurement and analog output. In addition, air carrying dust or oil (such as found in blower/compressor systems that utilize oil) can lead to coating of the sensor and thus inaccurate readings. Refer to the Maintenance section for information on cleaning the sensor. The FMA1000 is a bidirectional device, meaning the flow in the forward or reverse direction provides the same readings. The FMA1000 can be mounted vertically or horizontally without shift in calibration.

Installation

1. Remove the protective cap from the sensor tip.

2. Run a length of straight pipe before and after the flow sensor probe.
   The amount of upstream straight pipe required depends on the type of obstruction which is immediately upstream of the flow sensor requirements.

3. Downstream of the flow sensor, in all situations, run 5 diameters of straight pipe regardless of the downstream obstruction.

4. Align the sensor probe with the air flow.

5. Make sure the air flow is perpendicular to the sensor window.

6. The score line on the sensor tubing is another way of aligning the sensor to the flow stream.

7. The score line starts from the center of the sensor window and as a result it can be aligned properly.

8. One way of installing the sensor probe into a flow stream is to utilize a compression fitting such as Omega’s SSLK-14-14 stainless steel compression fitting with Teflon ferrule, which allows adjustment of the insertion depth of the probe.

9. Connect the 15 feet shielded Power/Output cable to the transmitter’s 10-pin male mating connector.

Main Operations

The FMA1000 transmitter has a built-in LCD backlit display and keypad. Using the display and the keypad, you can view the following parameters

• The air velocity & air temperature in real time Main Display.
• Maximum air velocity & temperature during the session.
• Minimum air velocity & temperature during the session.
• Volume air flow in Cubic feet per minute CFM.
• You can view and set the following parameters from the keypad:
• High Alarm set point for air velocity
• Low Alarm set point for air velocity
• Transmitter’s response time.
• This is the response time of the analog output and the display reading in real time.
• Cross sectional area of the air flow duct.
• Atmospheric pressure setting in millimeter of Mercury mmHg.

Changing Display Engineering units

You can change the air velocity Engineering unit display from Feet per minute FPM to meter per second (m/s), miles per hour (MPH), and kilometers per hour (Km/h) from the keypad Press key. You can change the Temperature display from ºF to ºC or vise versa by pressing the key.

Turn on Display Back light

You can turn the LCD backlight on or off by pressing the key. High & Low Alarm set points – You can set and enable the high & low alarm set points for the air velocity as shown in the keypad flow chart. When in the alarm condition, the HAL or LAL icon will flash on the LCD, and the corresponding alarm voltage output will go high. The alarm voltage outputs can drive external mechanical relays.

Display Volume air flow

The unit calculates volume air flow by multiplying the air velocity by the cross sectional area of the pipe or the duct. The cross sectional area can be set in the display menu as shown in the keypad flow chart in square inches units. The volume air flow is shown in Cubic feet per minutes. Table shows the Keypad Functional flow chart. Figure 5 shows the display functional flow chart.

Maintenance

Except for intermittent removal of the sensor from the line for cleaning, there is no routine maintenance for the FMA1000. If the sensor probe becomes coated with dust, blow the dust away with clean air. If the sensor probe is coated with sticky material, clean it with water or alcohol Ethanol using an artist’s brush.

Calibration

Each FMA1000 is individually calibrated in a NIST traceable wind tunnel. For calibration certification or calibrating to a new air flow range, the unit must be returned back to the factory.
