Installation
① Regardless of whether the flowmeter is installed vertically or horizontally, keep the flowmeter in a horizontal state.
② In situations where accidental gas stop or accidental gas stop will inevitably cause major irreversible losses, bypass must be installed.
③ There should be at least a 10D straight pipe section in the front of the flow meter and a 5D (D is the pipe diameter) straight pipe section at the rear.
④ If the instrument is installed outdoors, a sunshade should be added to avoid the sun and rain.
⑤ Make sure that there is no strong magnetic field, strong electric field and strong mechanical vibration near the flow meter.
⑥ The static grounding of the flowmeter should be reliable, but it cannot be shared with strong current grounding.
⑦ The surrounding environment should confirm that there is no corrosive effect on aluminum alloy.
⑧ Ensure that the gas flow direction is consistent with the arrow direction on the flow meter.
⑨ Welding operations are prohibited in an explosive environment.
Daily maintenance
In the daily operation of the thermal gas mass flow meter, check and clean the flow meter, tighten the loose parts, find and deal with the abnormality of the flow meter in operation in time, ensure the normal operation of the flow meter, reduce and delay the wear of components, Extend the service life of the flow meter. Some flow meters will become fouling after being used for a period of time, and it must be cleaned by pickling etc. depending on the degree of fouling
