But where the instrumentation, in the process of using the problem is inevitable, anti-corrosion electromagnetic flowmeter certainly can not be avoided a little problem, then how to cope with it, how to maintain the accuracy of it, this is a skill. The following Supmea will briefly introduce the anti-corrosion electromagnetic flowmeter failure how to cope with. Anti-corrosion electromagnetic flowmeter in the operation of the common faults caused by two kinds:
- 1、Electromagnetic flowmeter itself common failure, that is, the dashboard parts or electronics destruction caused by the common failure.
- 2、Common malfunctions caused by external causes, such as improper installation, fluidity changes, build-up and scale accumulation.
Anti-corrosion electromagnetic flowmeter without total flow data signal output, root cause and solution.
- (1)Abnormal instrument panel power supply system? Solution: Make sure that the switching power supply has been connected, check the switching power supply pcb circuit board output from all sectors of the working voltage is not everything is normal, or try to replace all the switching power supply pcb circuit boards, to identify its advantages and disadvantages.
- (2)Abnormal cable connection? Solution: Check whether the cable is intact and the connection is appropriate.
- (3)Liquid flow condition does not match the installation? Solution: Check the liquid fluidity orientation and whether the liquid in the tube is full. For pressure transmitters that can be accurately measured in the positive and negative directions, if the orientation is inconsistent with the accurate measurement, but set the display information of the total flow of positive and negative orientation does not match, it must be corrected. If the labour of removing the sensor is large, you can also change the orientation of the arrow symbol on the sensor and set the digital display instrument mark again. Pipeline is not full of liquid is mainly inductor installation parts of the improper place caused by the installation should be taken at the time of installation of effective, prevent the result of liquid in the pipeline does not satisfy the pipe.
- (4)Sensor parts destroyed or precise measurement of the inner cavity of the adhesion layer? Solution: Check the smart transmitter inner cavity electric level is not covered with liquid crust layer, for very easy to crust the precise measurement of liquid, to carry out on time to remove.
- (5)Converter electronics destroyed? Solution: If it is identified as a common fault caused by the destruction of the converter electronics, remove and replace the destroyed electronics.
The above is the anti-corrosion electromagnetic flowmeter manufacturer Supmea to explain, if you feel okay, buy a flowmeter before you go!
