- Clamp-on flowmeters
ELIS PLZEN a. s. has the priority sales rights to clamp on ultrasonic flow meters made by the Japanese company TOKYO KEIKI INC. in specific countries in Europe under a certificate of distributorship. The flow rate values are determined by the difference between the travel times of ultrasonic waves propagating in the measured liquid in and against the flow direction using the transit-time principle. The measurement is independent of the electrical conductivity of the measured fluid. Moreover, the ultrasonic transducers are clamped on to the outside of the pipe so it is not necessary to cut pipes or stop flow to install the meter and there is no pressure loss. The application of clamp on ultrasonic flow meters serves many functions across almost all lines of industry.
