Plug-in Thermal Gas Mass Flow Meter Installation Notes:
The plug-in thermal gas mass flow meter is a meter that measures the fluid flow using the principle of thermal conduction. The instrument uses a constant temperature difference method to accurately measure gas mass flow. It has the advantages of small size, high digitization, easy installation and accurate measurement.
1 The flowmeter should be kept horizontal regardless of vertical installation or horizontal installation.
2 In the event that accidental stoppage or accidental stoppage does not allow for a significant non-reversible loss, a bypass must be provided.
3 There must be at least 10D straight section in front of the flowmeter, and at least 5D (D is the diameter) straight section at the rear.
4 If the meter is installed outdoors, add a sun shield to avoid sunlight and rain.
5 There should be no strong magnetic field, strong electric field and strong mechanical vibration near the flowmeter.
6 Static grounding of the flowmeter should be reliable, but it must not be shared with strong grounding.
7 The surrounding environment should be confirmed to have no corrosion effect on the aluminum alloy.
8 Make sure that the gas flow is in the same direction as the arrow on the flowmeter.
9 It is prohibited to perform welding operations in explosive atmospheres.
10 The environment with special requirements for welding should be operated according to the relevant requirements.
It is forbidden to install the flow meter at the low point in the pipeline, otherwise it is easy to collect water and other impurities.
