Hardware failure

If there is an error is too large, Totalizer display is not lit or no value, the display is blank bits, etc. phenomenon, its causes:

a. non-standard installation, can directly lead to the meter zero drift, such as mass flow meter installed in the pump outlet closer, sensor support strong enough, improper connection flange welding stress signal cable by electromagnetic interference.


b. Wiring problem

If the display does not light phenomenon appears, check the power connection totalizer, if there burned fuse, make sure that the input voltage to the standard nominal voltage, AC and DC forms are the same. If there is another totalizer does not vary with traffic increases, you should check the totalizer wiring, if fitted totalizer forward / reverse procedure, check the meter wiring, because the flowmeter wiring is incorrect, make the totalizer in the reverse to not increment when the stream.


c. process media change

If the measurement media folder appears gas, gasification or two-phase flow phenomena, the transmitter will alarm display, serious, the sensor stops working.


d. Transmitter failure.


e. sensor failure.


f. purging pipe problem.
