ultrasonic water flow sensor, ultrasonic piezo transducer 1MHZ
Ultrasonic transducer application:
The ultrasonic flowmeter is used in conjunction with a piezoelectric transducer to measure the liquid flow rate by emitting ultrasonic waves in the liquid medium. In addition to flow measurement, ultrasonic piezoelectric transducers can also be used for liquid level measurement. These are mainly used for measurement applications, such as inspection, B-medical, beauty equipment, acoustic transducers, micro drives, ultrasonic heat meters, water meters, welders, cleaners, ultrasonic flow meters, etc.
Working principle of ultrasonic transducer:
Piezoelectric ultrasonic transducers are used in ultrasonic flow meters. They use sound waves to determine the speed of fluid flowing through a closed pipe, and their reflections to the fluid are the same. The transmitter processes the upstream and downstream time to determine the flow rate.
What is it made of: ultrasonic sensor:
The ultrasonic transducer of high frequency, which is made up of an active element, a backing, and wearplate. Its active element is a piezoelectric or single crystal material which converts electrical energy to ultrasonic energy. It will also then receives back ultrasonic energy and converts it to electrical energy.
