LDM partially filled Flow measurement

Ultrasonic transit time difference flow measurement for wastewater, raw wastewater and rainwater

High precision flow value acquisition

The LDM is a calibrated measuring device for backflow-free flow measurement of wastewater in open channels or open channels. 10 flow velocity measuring sections distributed over the entire cross section provide accurate flow values when the sensor is partially or fully filled. The level measurement is integrated in the device housing.

Versatile system

The contamination-resistant system is suitable for water, rainwater, sewage, raw sewage as well as biologically and chemically contaminated waste water. The powerful measuring device measures even the smallest filling levels extremely reliably.

Quick and easy assembly

The LDM is available without flanges and is clamped between two pipes with bolts / threaded rods. This versatile measuring device does not need to be calibrated on site, as the calibration is done completely at the manufacturing site.

Technical information

The LDM system is available from DN200 to DN1200 and is very resistant to abrasion and chemicals. All relevant elements of the robust construction have an ATEX approval (zone 1).

The system measures even the smallest filling levels with the highest reliability. 10 flow velocity measuring sections distributed over the entire cross section ensure maximum precision in flow measurement.

The LDM has the following device variants:

  • Different nominal sizes (see also product documentation, section 4.1 “Dimensions and weights”)
  • As part of a PNA (pneumatic discharge control from Stebatec)
  • As measuring point without connection to a PNA

Advantages

Precise and extremely robust system

  • Dirt-resistant system
  • Measures even the smallest filling levels extremely reliably
  • Rugged construction
  • Very resistant to abrasion and chemicals
  • Does not have to be calibrated on site, as calibration is already done at the manufacturing site
