Flow measurement in open flumes

Non-contact measurement
The quantity that enters a sewage plant is an important criterion for effective control of the complex system. The amount of air brought into the aeration basin depends on the amount of waste water that enters the plant. This controls the activity of the bacteria that break down the contaminating substances. To avoid the sensors getting dirty from the high solid content of the waste water, non-contact measurement of the flow volume is usually recommended.

Flow measurement with VEGASON 61
Because the flow volume in channels changes proportionally with the level height, the VEGASON 61 ultrasonic sensor with its non-contact measuring principle is the ideal solution for this particular measuring task. Without contact with the medium and the danger of contamination, the sensor accurately measures the level, and thus the momentary flow volume. All common flume profiles, like e.g. Venturi, V-Notch or weir, are already preprogrammed in the sensor software. Individual flume profiles can also be programmed by simply entering index values.

For heavy demands – VEGAPULS 61
Radar sensors like VEGAPULS 61 are also suitable for flow measurement in open flumes. For waste water treatment in chemical plants, where waste water temperatures change drastically or where solvents are contained in the waste water, the use of radar sensors is especially recommended.
