1. The quality flow meter DCS suddenly went to zero.

The flow meter experienced a key rolling fault. The automatic zeroing of the accumulated quantity at full range and the sudden zeroing of the mass flow meter DCS are both caused by residual faults in the flow meter and require timely maintenance. A mass flowmeter is a flow meter that continuously measures the flow rate of the measured medium, and the measurement results are displayed in units of weight such as kilograms or tons.

2. How to deal with inaccurate flow meters

1. Fluctuating measurement values 2. Inaccurate measurement values

3. There is a medium, but the instrument displays zero

4. The instrument has no display or no output. Common solutions are: 1. The reason for the fluctuation of measurement values may be a wiring problem (applicable to newly installed flow meters), usually due to poorly connected shielded wires; User process issues may cause dissatisfaction with the pipeline (possibly due to early installation not meeting installation conditions, which must be ensured to be full; during later use, the pipeline may not have an exhaust valve installed to hold air in the middle of the pipe). Check if the front valve of the flowmeter is fully open. If it is not fully open, it may cause fluctuations. Check if the conductivity is too low. If the conductivity is low, it may cause significant fluctuations. Check if the flowmeter has water ingress. If there is water ingress, it can be directly judged as a quality problem with the flowmeter. Measure if the sensor resistance is normal and use GS8 Test whether the converter is normal. If conditions permit, replace it with a normal one to try. 2. The reason for inaccurate measur

ement values may be that the user has mistakenly connected the wires. Check the wiring and whether the sensor and converter instrument numbers are consistent. If they are not the same set, check the pipe diameter GK、GKL、 The excitation frequency user should check whether the bypass pipe is closed and whether the medium is prone to scaling. If it is prone to scaling, it can also lead to inaccurate measurement. 3. The reason why the medium flow meter displays zero may be: check whether the connecting wire is normal, it is possible that the middle line is interrupted, check whether the pipe is full to confirm that the medium flows through the sensor, check whether the front and rear valves are open, check whether the conductivity of the users medium is within the appropriate range, and if the conductivity is low, check whether the threshold value is too high. 4. The reason why the instrument does not display or has no output may be: measure whether the users power supply is qualified, check whether the users output wiring is correct, use a multimeter to measure whether there is current output, and check whether the fuse in the converter core is broken (IFC3 There are two fuses, power fuse and output fuse; IFC100 has an insurance policy.

3. Precautions for using gas mass flow meters

When using gas mass flow meters, it is necessary to pay attention to correct installation, daily maintenance, standardized operation, and ensure safety. The specific precautions are as follows:

1. The correct installation position should be selected. The installation environment should be free of strong vibration, electromagnetic interference, and small temperature changes, and should be avoided from being installed in positi
