Level and pressure instrumentation for wastewater treatment: High efficiency with VEGA transmitters

Wastewater treatment plants place high demands on measurement technology, which has to withstand any kind of weather and deliver consistent, precise data. In addition to environmental conditions, costs play a decisive role in this price-sensitive segment. In the past, ultrasonic transmitters were the leading technology here. Today, radar level measurement is in no way inferior to ultrasonic level measurement in terms of cost efficiency – and they also offer significantly better performance.

VEGAPULS radar transmitters are not only comparable to ultrasonic transmitters in terms of price, but also offer outstanding accuracy as well as robustness and are maintenance-free – regardless of the ambient conditions. The VEGAPULS 10, 20 and 30 series transmitters use innovative 80 GHz technology, which impresses with excellent focussing of the radar beam and an impressive dynamic range. The centrepiece of these transmitters is the unique radar microchip developed and specially optimised by VEGA for the requirements of level measurement. Thanks to their small design, these transmitters are not only very compact, but also reasonably priced. Moisture, strong temperature fluctuations, dirt, buildup, sludge gas or cobwebs? No problem for radar transmitters!

VEGAPULS radar transmitters are used in different sections in wastewater treatment plants. Whether for level measurement in sewer networks, for weir control, for flow measurement in open channels, or for optimisation of pump controls to name just a few examples, because of their narrow beam angle, they are ideal for non-contact measurement, even in the most confined spaces. Even in tanks with installations no interfering signals are generated. The success speaks for itself: over 500,000 transmitters have been installed since their market launch. 

As an alternative to level measurement with radar transmitters, the VEGAWELL 52 hydrostatic pressure transmitter provides high measurement reliability, even with large installation depths. Its ceramic CERTEC® measuring cell offers high long-term stability even under extreme conditions. Integrated overvoltage protection reliably protects the electronics from atmospheric interference.

With the VEGABAR 10, 20 and 30 compact presssure transmitters, VEGA has now completed its pressure measurement portfolio in wastewater management. VEGABAR 38, for example, measures gauge, absolute or differential pressure of gases, vapours and liquids. The ceramic measuring cell operates with high precision and impresses users with its unique, very high overload resistance. The large display with plain text indication offers very good readability. A colour 360° status display ensures that switching conditions and status are quickly recognised.

Whether radar level or pressure measurement technology: VEGA transmitters offer decisive advantages. Reliable and precise measurement data and maintenance-free operation, combined with simple setup and cost-effectiveness, make the everyday work of wastewater treatment plant operators much easier – worldwide.
