Ultrasonic Flow meter

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. 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 or by measuring the frequency shift from the Doppler effect. They do not use moving parts, unlike mechanical flow meters.

Ultrasonic flow meter Overview

Ultrasonic flow meters are highly useful in a variety of applications across multiple industries.
No moving parts in ultrasonic flow meters, Since ultrasonic flow meters don’t involve moving parts, they last a long time with very little maintenance. As long as the meter is properly mounted and installed, these meters are highly accurate.
However, inline and insertion flowmeters are generally more accurate than clamp-on ultrasonic flow meters.

Ultrasonic flow meters Principle

Electromagnetic flow meters detect flow by using Faraday’s Law of induction.
Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage). Due to this, although it may appear as if there is nothing inside the flow pipe of an electromagnetic flow meter, flow can be measured.
