Product Details

Handheld ultrasonic flowmeter

Measurement medium: liquid Range: - Output signal: 4-20mA Accuracy level: ± 1% Medium temperature: -30 ℃~60 ℃ Explosion proof level: - Protection level:-

The TUF series ultrasonic flowmeter utilizes the principle of low voltage and multi pulse time difference, and adopts high-precision and ultra stable dual balanced signal detection and differential reception digital detection technology to measure the sound wave transmission time in the forward and reverse directions, and calculate the flow velocity based on the time difference. It has the characteristics of good stability, small zero drift, high measurement accuracy, wide range ratio, and strong anti-interference ability. When the ultrasonic beam propagates in a liquid, the flow of the liquid will cause a smile change in propagation time, and the change in propagation time is proportional to the flow velocity of the liquid. At zero flow rate, the time required for two sensors to emit and receive sound waves is the same (a technology that can actually measure zero flow rate); When the medium flows, the transmission time of sound waves in the reverse direction is greater than that in the water flow direction. The relationship conforms to the following expression: V=MD/sin2 θ * Δ T/Tup * Tdown
V: Medium flow rate
θ: The angle between the speed of sound and the direction of liquid flow
M: The number of straight line propagation times of sound beam in liquid
D: Inner diameter of pipeline
Tup: The propagation time of the sound beam directly above
Tdown: propagation time of sound beam in the opposite direction
Δt ： tup-down
