TUF-2000H Ultrasonic Flowmeter is designed to measure the velocity of liquid fluids in a closed pipe. Ultrasonic flow meter doesn't contact the liquid and is attached on a line with a clamp. This type of flowmeter does not get dirty and does not require maintenance and also the installations are quick and easy.
Receiving and transmitting transducers are mounted outside the line according to the determined distance between them. Depending on the diameter of the pipe and the characteristics of the liquid, transducers are placed according to one of the W method, V method or Z method.
There is a special sound frequency transmission between the two transducers of the ultrasonic flow meter. The transmitter transducer sends the sound frequency, and the receiver transducer receives this sound frequency. This audio frequency signal is provided by the fluid in the line between the receiver and transmitter. There is a time lag between when the transmitter sends the signal and when the receiver receives it. This time difference is directly related to the speed of the fluid. You can calculate these relationships by the following formula below:
Θ : Angle in flow direction
M : Ultrasonic signal transmission coefficient
D : Pipe diameter
Tup : Transmission time to signal of first transducer
Tdawn : Transmission time to signal of second transducer
