DESCRIPTION :
Ultrasonic Flowmeter is designed to measure the fluid of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. transittime flowmeter utilizes two transducers that function as both ultrasonic transmitters and receivers.
The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers
can bemounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by
transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the
transit time that it takes for sound to travel between the two transducers.
Linearity: 0.5%, Repeatability: 0.2%, Accuracy: ± 1 % Easy to operate. Several type transducers for selection, measuring
size is from DN15mm to DN6000mm Adopt low voltage, multipulse technology to improve accuracy, useful life and reliability.
Powerful Recording Function, record the totalizer data of the last 64 days/64 monthes/5 years. The wall-mounting flow meter can be applied to a wide range of pipe flow measurements. Applicableliquids include pure liquids as well
as liquid with small quantity of tiny particles.
