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.
