Wessex Water installs compound meter to reduce leaks


Bath, U.K. — (METERING.COM) — February 8, 2008 – U.K. utility Wessex Water has installed 50 MeiTwin water meters into public buildings with wide water demand fluctuations as part of a trial aimed at reducing leakage and unaccounted for water.

Sensus Metering Systems, which already supplies its WP Dynamic turbine bulk water meter for the measurement of high, relatively constant flow-rates, anticipates that the MeiTwin compound meter will overcome measurement issues connected with low flow-rates.

Mike Smith, Network Planning Engineer at Wessex Water, decided to use the Sensus 50 mm meters as part of a trial in schools, hospitals and hotels. The meters include a main meter to measure high flow-rates and a bypass meter to record consumption during periods of lower demand – and to identify leakage issues.

“Due to the large variation in the volume of water used in these types of establishments day and night, we needed a meter that could measure both high and low flow,” said Smith. “Previously installed meters were only able to measure high flow, leaving the low flow unmeasured. This unmeasured water loss contributes to our leakage figures, which are monitored by the government. Moreover, unaccounted-for water means a loss of revenue.”

Adam Parsonage, Regional Sales Engineer for Sensus comments: “The MeiTwin range measures the widest flow rates of any bulk meter in the UK. It provides Wessex Water with the ability to record water consumption with much greater accuracy, so ensuring that billing more fairly reflects usage.”   

The Wessex Water trial will run for a year to prove the effectiveness of the new bulk meter strategy.

The Sensus MeiTwin is a compound bulk water meter featuring a wide dynamic flow range. In almost all cases, thanks to its unique ‘in line’ design and advanced three-in-one measuring cartridge, the MeiTwin can be fitted with ease by a single installer. The product range is ideally suited to the traditional problems associated with the peaks and troughs of bulk metering applications – in hospitals and hotels, for example, where water demand escalates dramatically during early morning and declines later in the day.

The standard unit can be equipped with up to three pulsers and a choice of three different electronic registers, providing a data record for direct connection to building management systems.
