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.

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. How to use ultrasonic flowmeters. Working principle of the ultrasonic flow meter. Conversely the piezo electric crystal creates a.

The transit time differential measurement is based on a simple physical fact. 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. Ultrasonic flow meters use the principles of echo and variation in the speed of sound across different mediums to measure flow. 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. The article explains what you need to know about the basics of ultrasonic flow measurement and its applications. Ultrasonic flow meters operate using the transit time differential method. Each sensor alternately can transmit and receive ultrasonic signals.

The canoe moving with the flow needs much less time to reach the opposite bank. Ultrasonic flowmeters are available in sizes to 72 inches and larger. Ultrasonic flow meters have many applications from process flow to custody flow. Transit time designs are also available to measure gas and.

Inside the ultrasonic flow meter pairs of sensors are fitted across the tube in opposite to each other. The two transducers could either be mounted.
