Ultrasonic flow meters are inferential meters that use ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it. There are two types of ultrasonic flow meter technologies, including Doppler and transit time. In addition to inline models, ultrasonic meters are available as clamp-on solutions when contact with the measured fluid is not possible.
Ultrasonic flow meters are a popular solution to simplify flow measurement across a variety of applications.
Ultrasonic meters measure the velocity of a fluid flowing through a pipe in one of two ways: transit time or Doppler technology. Transit time technology measures the time differential between signals sent upstream and downstream. The differential is directly proportional to the velocity of the water. Doppler technology measures the difference in sound wave frequency reflected off gas bubbles or particles in the flow stream.
With this technology, ultrasonic waves transmit upstream and downstream through the pipe wall and liquid flowing in the pipe. By measuring the difference in the travel time and knowing the pipe size, the meter determines the velocity and flow rate. Transit time ultrasonic flow meters use two transducers, which mount to the outside of the pipe and function as both ultrasonic transmitters and receivers. The flow meters operate by alternately transmitting and receiving a frequency-modulated burst of sound energy between the two transducers.
This video explains why users often choose ultrasonic clamp-on flow meters instead of insertion electromagnetic counterparts. Learn how to select the best metering technology for your application.
Dynasonics® Ultrasonic meters measure flow rate by propagating ultrasound waves into liquid-filled pipes and measuring the reflections. With either transit time or Doppler technology, these clamp-on ultrasonic meters reside outside the pipe, providing flexibility across a wide range of pipe sizes, no pressure head loss, no contact with internal liquid and no moving parts to maintain.
E-Series® Ultrasonic meters use solid-state technology in a compact, encapsulated, weatherproof and UV-resistant housing—suitable for both residential and commercial applications. Equipped with an easy-to-read, 9-digit LCD display, the ultrasonic meter presents consumption, rate of flow, reverse-flow indication, and alarms. With no moving parts, the E-Series® Ultrasonic meter is virtually maintenance-free and has greater extended low flow accuracy compared to mechanical meters.
