Non-invasive, Ultrasonic Flowmeters Are Clear Winners in Wastewater Pumping Stations

Pumping stations are an integral part of each wastewater network. Flow measurement at such stations is critical as the quantities which are fed to the treatment plant have to be monitored.

Conventionally, magnetic inductive flowmeters are used for such measurement tasks. However, due the medium, which is heavily charged with solid matter, these instruments are subject to wear, leading to incorrect readings and subsequent failure.

Non-invasive ultrasonic flow meters prove to be the better measuring solution. Since these meters measure from outside the pipe wall, there is no wear and tear on the meter making them virtually maintenance-free. Furthermore, there is no need to open the pipe for installation, which would result in at least a partial interruption of operation. There isn't a need for multiple workers or heavy equipment for installation. The entire measuring system, consisting of ultrasonic transducers and a measuring transmitter, is easily carried to the measuring location and installed by a single person. There is no disconnection of pipes or flanged joints, unlike when installing a magmeter. Finally, there is no need for block valves to hold back flow during installation, repair, or replacement.

Advantages:
  • Reliable and accurate non-invasive wastewater flow measurement without any wear and tear or measurement drift
  • Extremely easy to set up a measuring point without any impairment of the plant’s normal operation
  • ATEX-certified transducers with protection degree IP68 for use in hazardous areas as well as in flooded chambers
