Abstract: steam flow meter scale no signal output process information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Steam flow meter with no signal output processing method 1, confirm with flow 2, supervisory power, across the electrodes at both ends of the voltage must be in 10. 5 - 50 VDC between A, if the voltage is zero, check the power supply fuse B, if the voltage is low but not zero, flowmeter may be loaded. More flow meter manufacturers choose model price quote you are welcome to inquire, below is the steam flow meter scale no signal output processing method the article details. Steam flow meter with no signal output processing method 1, confirm with flow 2, supervisory power, across the electrodes at both ends of the voltage must be in 10. 5 - A, if the voltage is zero between 50 VDC, check the power supply fuse B, if the voltage is low but not zero, flowmeter can load power supply. Open the terminal cover, disconnect the positive and negative poles, measuring the power supply voltage, if the voltage is normal, is that the power supply circuit is normal, will open the electronic module is the cathode in C, isolation cover, front terminal electronic module of red, yellow and green line disconnected, measuring the voltage between the red line and green line, if the voltage is normal, the electronic module is damaged, replace electronic module D, if still showed low voltage, the shell/terminal is damaged, replace shell or return the instrument to examine Foxboro repair 3, 4 - A and 4-20 ma output circuit 20 ma loop can be through the field test socket on output terminal board testing, its produce 0. 1 - 0. Voltage signal and 4-5 20 ma current signal corresponds, before this, please ensure switch J in a state of because the test socket is not available in pulse output mode B, increasing flow to make sure the instrument is not under the scope of work and low flow blocking. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
