FLOW METERS
FA Series
■ Sensor
A thermal mass flow meter sensor enables
accurate measurement even in the case of
gas temperature and pressure fluctuations.
Sensor structure
The FA Series flow meter measure flow rates using heat from the heater
and a temperature sensor. In a no flow state, the air temperature
distribution around the heater is uniform, so there is no difference in the
temperature between the upstream and downstream temperature sensor
positions. When flow is received in this state, the downstream temperature
rises while the upstream temperature falls, so a temperature difference
between the upstream and downstream sensor positions is generated.
This temperature different is measured and a flow rate is calculated.

■ Rotary display
The display of the flow meter can be rotated 90° to the left or 180° to the right,
making it easy to read regardless of whether piping is horizontal or vertical.

- Page 1 Sensor structure FL O W The FA Series flow meter measure flow rates using heat from the heater and a temperature sensor. In a no flow state, the air temperature distribution around the heater is uniform, so there is no difference in the temperature between the upstream and downstream temperature sensor positions.

Page 2: Example Of Use
● Reverse flow detection function FA Series flow meters can display a reverse flow (flow in the opposite direction from unit's flow arrow) up to 30% of the maximum flow measurement range, and flow integration. However, reverse flow measurement accuracy is approximately ±6%FS, and analog output and switch output (except for some integrating functions) is not possible. - Page 3 FAS-120 74 to 76 [654.974 to 672.676] 5. Take care to keep foreign matter from flowing into the FA Series Flow Meter. Any rust, water droplets, oil mist, dust, or other foreign matter inside piping that gets into the FA Series Flow Meter creates the risk of measurement error and damage to the flow meter.

Page 4: Mounting Direction
Down installed upstream from the FA Series Flow Meter, be sure to provide a straight pipe section as recommended. See "Specification accuracy and straight pipe section" for more information. Failure to provide a straight pipe section can cause flow rate errors. - Page 5 When connecting one size larger piping (for example, 1/2B for the FAS-002), take the Install the FA Series Flow Meter so the arrow marked on its label is pointed in the specified value*+5D for direct piping before the flow meter and the specified value*+5D for the same direction as the fluid flow direction.
