Analysis of common faults of vortex flow meter
1. There is fluid flow in the pipeline after power-on, but no signal output
1. There is fluid flow in the pipeline after power-on, but no signal output
a. Check whether the wiring of the instrument is correct and whether there is a broken line;
b. Check whether the instrument is installed in the correct direction.
c. Check whether the traffic is below the normal range.
2. There is no fluid flow in the power-on pipe, but there is signal output
a. Check whether the instrument is grounded and whether interference is introduced due to poor grounding;
b. Check whether the pipeline has strong mechanical vibration;
c. Check whether the environment has strong electromagnetic interference, such as high-power electrical appliances or frequency converters and other strong electrical equipment;
d. Check whether the sensitivity is too high.
3. The flow of fluid in the pipeline is stable and meets the flow requirements, but the output changes too much and is unstable
a. May be poorly grounded to introduce interference;
b. It may be that the pipeline vibration is too strong to introduce interference;
c. The sensitivity may be too low, there is a leakage trigger phenomenon, improve the sensitivity can be.
4. The displayed traffic is inconsistent with the actual traffic, and the error is large
a. The instrument parameters may be set incorrectly;
b. May be the temperature and pressure instrument measurement error is too large;
c. The flow may be lower or higher than the normal flow range;
d. It may be that the installation does not meet the requirements, such as the installation of different cores, obstacles in the pipeline, and insufficient straight pipe sections.
