Section 2 - 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 follows:
• 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 bi-directional 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

Section 3 - 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. See Table 1
for specific requirements. Downstream of the flow sensor, in all situations,
run 5 diameters of straight pipe regardless of the downstream obstruction.
3. Align the sensor probe with the air flow. Make sure the air flow is
perpendicular to the sensor window. The score line on the sensor tubing
is another way of aligning the sensor to the flow stream. The score line
starts from the center of the sensor window and as a result it can be aligned
properly.
4. 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.
5. Connect the 15 feet shielded Power/Output cable to the transmitter’s 10-pin
male mating connector. Follow the wiring information below:
