Ultrasonic Water Flow Meter Working Principle

The two transducers could either be mounted.

Ultrasonic water flow meter working principle.

Simultaneously the transit time of these signals are measured. It is also a common practice to use a clamp on ultrasonic flow meter to verify other flow meters or for temporary measurement. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. The article explains what you need to know about the basics of ultrasonic flow measurement and its applications.

Inside the ultrasonic flow meter pairs of sensors are fitted across the tube in opposite to each other. Each sensor alternately can transmit and receive ultrasonic signals. Transit time designs are also available to measure gas and. The canoe moving with the flow needs much less time to reach the opposite bank.

Working principle of the ultrasonic flow meter. Imagine two canoes crossing a river on the same diagonal line one with the flow and the other against the flow. How to use ultrasonic flowmeters. The ultrasonic signals are generated by piezo electric crystals applying a voltage.

Ultrasonic flow meters use the principles of echo and variation in the speed of sound across different mediums to measure flow. Ultrasonic flow meters have many applications from process flow to custody flow. Conversely the piezo electric crystal creates a. The meters typically contain two ultrasonic transducers with one acting as the transmitter and the other as the receiver.

Ultrasonic flowmeters are commonly applied to measure the velocity of liquids that allow ultrasonic waves to pass such as water molten sulfur cryogenic liquids and chemicals. Using ultrasonic transducers the flow meter can measure the average velocity along the path of an emitted beam of ultrasound by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow.
