QT621 portable ultrasonic flow meter is a type of portable instrument for non-invasive, quick flow and energy measurement with clamp-on technology for many types of piping. Portable ultrasonic flow meter support quickly verify the flow reading of another meter and to data log flow system values over an extended time period. The meter can be easily moved and installed in different pipes and convenient to carry site to site. The innovative design includes matched precision transducers and signal processing circuitry to accurately measure the flow of most liquids over a wide range of velocities. Its portability makes it an excellent choice for measuring flows throughout the plumbing infrastructure to verify sensor pump and valve performance.
QT621 Portable ultrasonic flow meter is easy to install which could reduce installation time and cost. With no pressure head loss, no moving parts which is very easy to maintain and replace. Support BTU function, could be used as a portable type BTU (energy) meter. Compared with other type of flow meters, portable type ultrasonic flow meter could be easily moved and convenient to carry in different sites.
QT621 ultrasonic flowmeter is widely applied in oil industry, water treatment, pure water, chemical and etc.
