Volumetric flowmeter chosen for sewage plant

Channelmag, the volumetric flowmeter designed to measure flow in open channels and half-filled pipes, has been specified by Saur UK for the new Glasgow West Sewage Treatment Plant.

Channelmag, the volumetric flowmeter marketed in the UK by Arkon Flow Systems and designed to measure flow in open channels and half-filled pipes, has been specified by Saur UK for the new Glasgow West Sewage Treatment Plant.

The new facility, which has been designed and built by Stereau, the French Saur subsidiary, for the West of Scotland Water Authority, will have a capacity of 600,000 population equivalent.

In an unusual configuration, two 800mm wide Channelmags have been specified to operate side-by-side in a 2m channel containing raw sewage at a flow rate of up to 10m/min.

This flow rate is quite exceptional and believed to be the highest ever recorded for this type of application in Europe.

The units were preferred to conventional equipment as they are able to operative effectively without flumes, thus eliminating the risk of the sewage backing up.

They require only a straight length of 7x channel width upstream and 4x channel width downstream.

The two units have been supplied with ultrasonic level sensor and the latest Top-VHR-3 digital combined flow and level convertor.
