What happens if an electromagnetic flowmeter has no numerical display?
Thread Content
There is water inside the pipes on site; no jumper wires have been installed, nor are there any grounding wires. Do these have an impact? I tried grounding and cross-border temporarily, but it still didn’t work
According to the table header, it is still SYS or FGP
If no jumper wires are used for the pipeline and there is no grounding wire, it will have an impact, but not a very significant one. The operating conditions are not clearly described, so it’s difficult to determine the specific issue. 1. Whether the flow rate is within the measurement range; if the instrument is selected with a large range but the actual flow rate at the site is very low and thus outside the instrument’s measurement range, the above situation will occur ； 2. Whether the dielectric constant of the medium meets the requirements of the electromagnetic flowmeter; if the dielectric constant is below the required level, measurement is not possible ； 3. Check whether the instrument settings are reasonable.
Check whether the flow meter is installed in the wrong direction.
How’s SYS? What about FGP then? I’d like to ask for advice
SYS is a system alarm, indicating that there is a short circuit somewhere; it could be an issue with the wiring. FGP is an air traffic control alarm: the medium must not fill the tank completely. This allows the cause of the fault to be determined from the gauge. If it’s not due to these two reasons, then we need to check aspects such as product selection and installation.
Whether it is connected or not only affects flow fluctuations; there will be no issue of no display
Bridging and grounding have no impact; if there are no values, first check whether the power supply and signals are active and whether the circuits are at full capacity.
Check whether the wiring is correct, or use a replacement method by swapping out the circuit board, etc
Everything in this situation can run well. However, it is recommended to ensure that the flow meter jumper wires are properly connected.
