PolluFlow® Flow Sensor

Overview Industries & Applications Documentation & Tools


The PolluFlow® ultrasonic flow sensor with volume pulse output has been designed for use with the PolluTherm® integrator for measuring heating and cooling energy. The measurement principle is based on the state-of-the-art ultrasonic technology.

Ultrasonic technology offers many benefits: no moving parts, low pressure loss, wide flow measurement range and sensitive to low flow, large metering dynamics, and insensitiveness to suspended particles.

Benefits to you

  • Ultrasonic principle; no moving parts in the flow sensor
  • Available sizes from qp 0.6 to qp 60 (DN15 to DN100)
  • Separately certified calculator, temperature sensors and flow sensor
  • Service-friendly design enables cost-effective reprocessing once calibration period has expired
  • Together with our PolluTherm integrator, PolluFlow offers the same handling, same module, same communications and same operation
  • Horizontal, vertical and inclined installations available in all sizes
  • Very good long term stability approved by AGFW duration test on the PolluFlow flow sensor
