How to Test check mass flowmeter mass flow controller signal communication status

Step

An Application commercially available nitrogen cylinder pressure regulator to the following 3kg/cm2

(2) using 1/4 "SWL or 1/4" VCR fittings connected flowmeter

3 would AC110/200V turn DC15 power supply connected to power meter

4. Dsub9 or Dsub15 head pin input / output signals and three Multimeter Measurement

5. DC0 ~ 5V than the flow range of the flowmeter itself can be measured to the current conduction flow

6 using flow control device to adjust the flow rate outlook Chubby correctness

7 through the flow control device adjustment knob to adjust the output (for flow controller is the input signal)

8 and using terminal bus control signals measured value

 

Precautions

Mass flowmeter general standard for the DC power

Flowmeter sensing core is afraid too high (over 10kg./cm2) flows into the

Do not use wet gas test (such as pneumatic gas, usually air ...)
