4. Place the FLM in sample mode by
moving the black handle to the right.
Pressure will be shown on the pressure
gauge (PI).
5. Adjust the flow to the desired rate.
1/4 in. systems - use the metering valve
that is integral to the flowmeter.
1/2 in. systems -
■
Gas systems: use the needle
valve (NV1) that is upstream of the
flowmeter.
■
Liquid systems: use the needle valve
(NV1) downstream of the flowmeter.
System Startup
1. Place the FLM in bypass mode by
moving the black handle (BV1/BV2) to
the left.
2. Configurations 3 and 4 - Close the
sample return valve by moving the red
handle (BV3/BV4) to the up position.
3. Open flow to the FLM by opening all
fast loop in, fast loop out, and process
return lines. Since the FLM is in bypass
mode, allow your system to run for a
minimum of five minutes in order to flush
the sample return lines.
Configurations 3 and 4 - verify the plug
valve (PV) is closed.
