Smart gas Roots (waist wheel) flow meter Intelligent gas waist wheel (Roots) flowmeter is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. Gas is a compressible fluid, and its volume value is closely related to temperature and pressure. In order to unify standards for both parties, it is necessary to convert the actual volume into a standard volume under reference conditions (101.325 kPa 20°C). In order to achieve this purpose, the smart gas waist wheel flowmeter can accurately correct the volume of gas; it is an ideal instrument for gas measurement in urban gas, petroleum, chemical, electric power, metallurgy and other industries. more

1Product overview
The TUF series ultrasonic flowmeter utilizes the principle of low voltage and multiple pulsation time difference, adopts the high-precision and ultra-stable differential transmission of double-balanced signals and differential receiving digital detection technology to measure the acoustic wave transmission time in both the downstream and counter-current directions, and calculates the flow rate according to the time difference.It has the characteristics of good stability, small zero drift, high measuring accuracy and high anti-interference of measuring range over wide.
When the ultrasonic wave velocity propagates in the liquid, the liquid flow will make a slight change in the propagation time. The variation of the propagation time is proportional to the liquid flow rate and zero flow rate. When the two transmitted gases emit and receive sound waves, the time required is exactly the same (the only technology that can actually measure zero flow rate).When the medium flows, the acoustic wave transmission time in the reverse direction is greater than that in the flow direction.Its relation conforms to the following expression:
V: Medium flow rate
θ: The angle between the velocity of sound and the direction of liquid flow
M:The number of times the velocity of sound propagates in a straight line through a liquid
D: Pipe inner diameter
Tup : Propagation time of sound velocity in the positive direction
Tdown : Propagation time of sound velocity in inverse direction
∆T: Tup-Tdown
