Pulsar’s unique twin-transducer DUET, provides the highest accuracy non-contact ultrasonic flow measurement system available anywhere.
Only DUET features Pulsar’s unique, patented, approach to the issue of accuracy when temperature and echo reflection time varies. Both transducers fire together. By continuously monitoring the phase difference of the echoes, and because the distance between the transducer faces is known and constant, the speed of sound is continuously updated in real time on the process. The resulting accuracy and stability is exceptional.
Most accurate open channel flow system in the world!

Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing.
Flowmasonic WUF 100CF is designed to measure flow velocity of liquid in pipes such as clean water, dirty water demin water, chemical water, seawater, wastewater and others
