Level Measurement & Control


Challenges for level measurement in sewerage plants

November 2006 Level Measurement & Control

The quantity of product entering a sewerage plant is an important consideration for effective control of the complex system. The amount of air brought into the aeration basin depends on the amount of wastewater 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 wastewater, non-contact measurement of the flow volume is usually recommended. Vega has an ideal ultrasonic sensor, the Vegason 61, which can measure speedily and accurately the changing level height in channels, as the flow volume changes.

In the majority of sewerage treatment plants, the inflowing water is transported via screw conveyors or pumps. The main inlet chamber level is used to control the rate of pumping. Some sewerage treatment plants operate only on a minimum/maximum point level detection, but continuous level measurement using ultrasonic sensors has a proven and established track record. For level measurement of the pump well, the Vegason 63 non-contact device is ideal.

The ultrasonic sensors of the Vegason series are especially suitable for application in sewerage plants due to their efficient transducers. Wiring and installation are minimised because of their two-wire technology. Parameter adjustment is easy and the sensor is maintenance-free for continuous operating conditions.
