In the GTS online product shop, you will find a broad range of Ultrasonic Flow Meters that will fit a variety of applications and industries. Ultrasonic Flow Meters are inferential meters that implement ultrasonic technology to measure the velocity of acoustically conductive liquid that is moving. The two types of ultrasonic flow meter technologies are: Doppler Shift and Transit Time.
Transit-Time measures the time differential between signals sent both downstream and upstream. This differential is proportional to the velocity of the water. Transit-Time meters are best applied in the use of measuring the flow of clean liquids and are, as a result of this, generally the most popular type of ultrasonic flow meter. Doppler Shift acquires and measures the difference in frequency of the existing sound wave that is being reflected off particles or gas bubbles and is suitable for liquids that are classified as dirty or aerated.
GTS stocks a variety of Ultrasonic Flow Meters that suit every application. Whether you are looking for the Clamp-On DFX Doppler Ultrasonic Flow meter, featuring a non-intrusive design and wide-velocity range, or if you are in the market for the TFX-500w Transit-Time Ultrasonic Flow meter that features a Bi-Directional Flow Measurement System and no moving parts to maintain, prolonging the longevity of the device’s service life, GTS will provide you with the perfect instrument to suit whatever application you need.

Q: What are the different types of ultrasonic flow meters?
The two basic types of ultrasonic flow meters are the transit-time and Doppler meters. They are also often referred to as ultrasonic water meters and ultrasonic flow sensors.
Q: How do ultrasonic flow meters work?
Ultrasonic flow meters use sound waves to measure the velocity of fluid flowing through a pipe and convert that data to the volume.
Transit time flow meters measure the time difference between the travel time of an ultrasound wave going with the fluid flow and against the fluid flow. The time difference is used to calculate the velocity of the fluid travelling in a closed pipe system.
Doppler meters use sound waves reflected off materials in the fluid, such as air bubbles or particulates, to measure flow velocity.
Q: How accurate are ultrasonic flow meters?
Accuracy for volumes >50mm: ±1% of reading or 0.0003m/s, whichever is greater
Between 25 and 50mm: ±1% of reading, ±0.01m/s
20mm and smaller are accurate to ±1% full scale
Q: How do clamp-on flow meters work?
A clamp-on ultrasonic flow meter consists of at least two ultrasonic sensors mounted externally to a pipe. The sensors measure flow by transmitting and receiving ultrasonic signals directly through the pipe wall and medium. How the flow rate is determined varies depending on the nature of the application.
