The flow rate is inaccurate, either too high or too low, or the flow meter is no flow rate displayed.

Make sure it conforms to the requirements of pipe connection in the manual, the gas tpye meets the requirements and the air pressure reaches the driving standard of 0.1MPa and there is no vibration or interference in the installation environment.

Nozzle requirements for inlet and outlet of flowmeter.

Please follw the manual to reserve a straight part of the inlet and outlet, the installation environment should avoid vibration and electromagnetic.

For the same pipeline, the flowmeter values differ greatly.

The flow rate read by the product varies due to the different positions placed, resulting in different pressure resistances.

What gases can our flow meters measure？

Our gas flow meters can only measure single gases(AIR O2 N2 AR CO2), mixtures cannot be detected, gases need to be dry and clean without water vapor and oil gas.
