How to choose the gas flowmeter?

General customers do not know what kind of gas flowmeter to choose for the purchase of measuring gas flowmeter, often found after the purchase is not suitable and as a waste of cost.How to choose the gas flowmeter suitable for your working condition is a difficult choice for the customer who just contacted. According to many years of instrument sales and field experience of NONCON instrument, we will tell you what conditions you need to know when selecting the gas flowmeter.

The first point, we have to know the working condition, gas meter, model selection of the general customers need to know how's the size of the pipeline, unit operation need how much is the pressure pipe, the pipe measuring gas, pipeline within the medium temperature is how much, this is basic is also the customer needs to provide parameters.

The second point, we know some basic parameters of the above said, the customer wants to know what kind of function you need to meet their own needs, such as customer only need the scene in situ show that observation can, gas meter meter power supply way we choose to 3.6 V lithium batteries can be, if you need to far to secondary instrument or class of PLC system, the gas meter header we can choose 4-20 ma output.

The third point, gas flowmeter selection when we have to choose the appropriate depending on the type of gas meter to measure, such as the measurement of natural gas, generally we choose the precession vortex flowmeter, gas turbine flowmeter, roots flowmeter, high requirements for trade calculation generally choose roots and gas turbine flowmeter, and of course the price is more expensive.


For internal assessment, we can choose the cheaper vortex flowmeter and vortex street flowmeter;For the oil gas, oxygen, for example, choosing gas flow timing we never choose displacement, is roots flowmeter) (also called gas lobed rotor meter, because it is the internal structural formula of gear, gear oil, for oxygen will be an explosion, then we can use a vortex street flowmeter or thermal mass flowmeter such oil-free to measure gas flow
