Ultrasonic flow rate sensor in robust inline design.
 
 

 
Suitable for water, oil and glycol solutions.
  • For volumetric flow quantities up to 200 l/min.
  • Measurement of non-conductive water also possible.
  • Binary, analogue and pulse outputs for signal processing.
  • Flow rate, totalising and medium temperature indication.
  • Different process connections possible using adapters.

Measuring principle
The ultrasonic flow rate sensor of type SU operates according to the transit time difference principle. Two sound transducers are positioned in a defined pipe length. These sound transducers alternately emit sound pulses. The pulse trains emitted with the flow in the pipe length are transported faster to the receiver by the flowing medium. This transit time difference results in the current volumetric flow quantity.

High functionality
In addition to simple flow rate monitoring the SU also monitors the temperature of the medium. It is displayed on the unit and provided for signal processing. The system is particularly suited for monitoring cooling circuits.
