Quattroflow Leviflow

Single-Use Flow Measurements especially adjusted for Quattroflow Pumps. LEVIFLOW® flowmeters are designed for noninvasive flow measurements of high-purity fluids with flexible tubing.

Two piezoelectric transducers, mounted in the sensor housing, generate and receive an ultrasonic wave. The difference of the transit time of both waves is proportional to the velocity and direction of the fluid. Measurement is based on ultrasonic waves those signals are changed due to flow velocity.

The flowmeters are available in two versions:

  • Inline Sensor – Specially calibrated to fit Quattroflow flow range
  • Clamp-On Sensor
