The clamp on ultrasonic flow meter for water, it is non-contact ultrasonic flow meter BTU meter heat meter and non-invasive flow meter, utilizes the transit-time, or also known as “time of flight” principle to measure the velocity of relatively clean liquids in full pipes. It features clamp on(strap on) designs with transducer arrangements that can detect in-site flow rates from outside of the pipework, without any interruption to flow or process. Clamp on ultrasonic flow meter with logger are specially chosen for water application, such as potable water, wastewater, cooling and heating water, ultrapure water. In this series we provide in-line ultrasonic flow meters as well as portable ultrasonic flow meter.
