Ultrasonic Water Flow Meter Working Principle

Imagine two canoes crossing a river on the same diagonal line one with the flow and the other against the flow.

Ultrasonic water flow meter working principle.

Transit time designs are also available to measure gas and. Ultrasonic flow meters have many applications from process flow to custody flow. The meters typically contain two ultrasonic transducers with one acting as the transmitter and the other as the receiver. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow.

The two transducers could either be mounted. Working principle of the ultrasonic flow meter. Simultaneously the transit time of these signals are measured. 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.

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. The article explains what you need to know about the basics of ultrasonic flow measurement and its applications. The transit time differential measurement is based on a simple physical fact. Ultrasonic flow meters operate using the transit time differential method.

The ultrasonic signals are generated by piezo electric crystals applying a voltage. Ultrasonic flowmeters are available in sizes to 72 inches and larger. It is also a common practice to use a clamp on ultrasonic flow meter to verify other flow meters or for temporary measurement. Conversely the piezo electric crystal creates a.

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.
