Rittmeyer offers precision flow sensors for closed pipes as well as open channels and partly filled pressure tunnels. The flow in closed pipes can be measured both with sensors mounted to the inside or outside of the pipe as well as non-invasive sensors installed on a mounting frame on the outside of the pipe.

Externally mounted (non-invasive) sensors for closed pipes

RISONIC clamp-on

The clamp-on sensor installation on the outer pipe wall allows for non-invasive, cost-effective, and low maintenance flow measurements using ultrasound technology. For temporary measurements, the mounting frame can remain at the measuring point for regular flow checks.

  • Easy placement: Magnetic attachment of the sensor
  • Alternative adhesive attachment
  • Ideal for temporary measurements
  • Installation possible in partially exposed pipes as well
