Details

The Sigma Down-Looking and In-Pipe Ultrasonic Sensors are excellent non-contact flow monitoring solutions for level measurement in combination with the Sigma 950 Flow Meter. These extremely low maintenance sensors provide high resolution data and are often used with weirs, flumes and other hydraulic structures to determine flow. The In-Pipe Sensor is designed to greatly reduce ultrasonic dead band so that it can be mounted directly in the sewer pipe and still transmit accurate date even at almost full levels.


Additional Features:
Excellent in:

  • Redundant level verification scenarios
  • High velocity sites
  • Use with flumes, weirs and other hydraulic structures
