Processing method for no signal output of steam flow meter

Abstract: The information on the processing method of no signal output of the steam flow meter is provided by the excellent manufacturers of flow meters and flow meters. Steam flowmeter without signal output processing method 1. Confirm that there is flow 2. Monitor the power supply, the voltage between the positive and negative terminals must be between 10.5-50VDC A. If the voltage is zero, check the power supply fuse B. If the voltage is very low but not Zero, the flowmeter can be loaded. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the processing method of no signal output of steam flowmeters. Steam flowmeter without signal output processing method 1. Confirm that there is flow 2. Monitor the power supply, the voltage between the positive and negative terminals must be between 10.5-50VDC A. If the voltage is zero, check the power supply fuse B. If the voltage is very low but not Zero, the flowmeter may be loaded with power. Open the field terminal cover, disconnect the positive and negative poles, measure the supply voltage, if the voltage is normal, the power supply circuit at this point is normal, reconnect the positive and negative poles to C, open the electronic module isolation cover, and connect the red , The yellow and green wires are disconnected, measure the voltage between the red wire and the green wire, if the voltage is normal, the electronic module is damaged, replace the electronic module D. If the voltage is still low, the shell/terminal is damaged, replace the shell or return the meter Go to Foxboro for repair 3. Check the 4-20mA output circuit A. The 4-20mA circuit can be detected by the test socket on the field output terminal board, which generates a voltage signal of 0.1-0.5 corresponding to a current signal of 4-20mA. Make sure switch J is off as the test socket is not available in pulse output mode B. Increase the flow to confirm that the meter is not operating below the low flow blocking range. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Steam flow meter no signal output processing method'
