Town dweller begins to use natural gas, and the metering clearing of natural gas dosage are the necessary equipments of natural gas motorcar, be Household water,
One of electricity, three table of gas, domestic gas meter used at present are substantially the epithelium table based on positive-displacement principle, which is that input is mechanical
Formula table, epithelium one inside open one and movement measured, measuring accuracy is limited, and water of the epithelium inside natural gas,
Under the influence of oil and dust, meeting gradually aging, therefore measuring accuracy can gradually be deteriorated, and epithelium table is limited by principle itself, no
It can be carried out miniaturization.
Ultrasonic flowmeter is to the effect of supersonic beam (or ultrasonic pulse) by detection fluid flowing with measuring flow
Instrument.Ultrasonic flowmeter can make more stable instrument measurement signal, strong antijamming capability, metering more acurrate.It can be widely applied
In fields such as petroleum, chemical industry, metallurgy, electric power, plumbing, natural gases.
The principle of ultrasound flow is mainly, and when ultrasonic beam is propagated in gas, the flowing of gas will make to propagate
Time generates minor change, and the variation in its propagation time is proportional to the flow velocity of gas.Ultrasonic wave gas metering device is logical
It crosses ultrasonic test detected fluid speed and obtains metric results, therefore the pressure regulator valve on the flow speed stability of detected fluid, pipeline
Pollutant (solid particle, moisture and oil gas in such as tested combustion gas) in the noise and detected fluid generated with switch valve
Factor influences whether the measuring accuracy and quantification stability of supersonic wave metering device.
