● Whether it is an industrial frequency disturbance (50HZ), characteristic: a value is displayed that does not change;
this value can be calculated according to the following formula
q—instantaneous flow rate (m3/h)
f — frequency (HZ)
K — coefficient (times/m3)
● Whether the wiring is laid in a line slot with strong electricity (220V or 380V) and whether the shield is grounded
● Is there any interference from frequency converter or motor operation near the instrument
In summary the solution.
1. The small flow does not affect the normal flow and can be removed
2. Space interference, replace the installation location or use an iron cover on
3. Line wiring interference requires good shielding or changing the wiring lines
4. power supply interference, then replace the power supply or add a filter
5. Replace the anti-interference ability of the table head
