LDM partially filled Nominal diameter 400

Wastewater treatment plant Langnau im Emmental, wastewater storage basin Zeughaus

Situation

  • The customer wanted a precise and reliable measuring device to limit the amount of material being forwarded.
  • Partial measurements such as individual flow speeds and measured filling heights should be recorded transparently and be viewable to verify the measurement results.
  • The measuring device has to provide accurate measured values in partial filling and full filling.
  • The measurement shall provide precise measured values regardless of the position of the downstream throttle valve.

“The LDM is a very intuitive system. The transmitter provides the information I need at a glance”  Hans Stucki, plant manager of WTTP Langnau

Products in use

Ultrasonic transit time difference flow measurement for wastewater, raw wastewater and rainwater
Highly precise flow value acquisition. The LDM is a calibrated measuring device for backflow-free flow measurement of waste water in open channels or free flowing lines. 10 flow velocity measuring sections distributed over the entire cross section provide most accurate flow values when the sensor is partially or fully filled. The level measurement is integrated in the device housing.
