Check Turn the power supply on if not already energized Allow for a 1 hour warm up Stop all flow through the instrument and wait 2 minutes Caution Do not assume that all metering valves completely shut off the flow Even a slight leakage will cause an indication on the meter and an apparent zero shift For the standard 0 5 VDC output adjust the zero potentiometer located on the lower outlet side of the Flowmeter until the meter indicates zero For the optional 4 20 mA output adjust the zero potentiometer so that the meter indicates slightly more than 4 mA i e 4 03 to 4 05 mA This slight positive adjustment ensures that the 4 20 mA current loop transmitter is not in the cut off region The error induced by this adjustment is approximately 0 3 of full scale This zero should be checked periodically during normal operation Zero adjustment is required if there is a change in ambient temperature or vertical orientation of the Flowmeter controller 2 6 3 High Pressure Operation When operating at high pressure the increased density of gas will cause natural convection to flow through the sensor tube if the instrument is not mounted in a level position This natural convection flow will be proportional to the system pressure This will be seen as a shift in the zero flow output that is directly proportional to the system pressure 2 6 4 Blending of Gases In the blending of two gases it is possible to maintain a fixed ratio of one gas to anoth

18. er In this case the output of one flow controller is used as the reference voltage for the set point potentiometer of a second flow controller The set point potentiometer then provides a control signal that is proportional to the output signal of the first flow controller and hence controls the flow rate of the second gas as a percentage of the flow rate of the first gas EXAMPLE Flow controller A has 0 100 slpm range with a 5 00 volt output at full scale Flow controller B has 0 10 slpm range with a 5 00 volt output at full scale If flow controller A is set at 80 slpm its output voltage would be 4 00 volts 80 slpm 100 slpm x 5 00 volts 4 00 volts If the output signal from flow controller A is connected to the command potentiometer of flow controller B it then becomes a variable reference voltage for flow controller B proportional to the flow rate of flow controller A If the set point potentiometer of flow controller B is set at 50 of full scale and the reference voltage from flow controller A is 4 00 then the command signal going to flow controller B would be 2 00 volts 4 00 volts x 50 0 2 00 volts The flow of gas through flow controller B is then controlled at 4 slpm 2 00 volts 5 00 volts x 10 slpm 4 slpm The ratio of the two gases is 20 1 80 slpm 4slpm The mixture of gas A is 95 2 80slpm 84slpm and the mixture of gas B is 4 8 4 slpm 84 slpm Should the flow of flow controller A drop to 78 slpm flow controller
