Clamp-on meters boost energy use information
May 1st 2005

Clamp-on heat meters from Micronics are improving energy efficiency and monitoring for Luton Borough Council.

UF 2000 units have been supplied and installed at a cost Micronics believes to be 40% less than alternative in-line meters at the local authority’s sites. They are used to measure and monitor heat energy distribution from central boiler house installations.

The Council has to comply with Part L2 of the Building Regulations when replacing or upgrading heating plant. These specify that it is deemed reasonable to expect that at least 90% of annual energy consumption be accounted.

The ultrasonic heat meters were chosen because they are noninvasive.

Benefits claimed include: significantly lower installation costs, less disruptive than installing an alternative in-line meter, and avoidance of residual venting problems associated with system drain down.

At Luton Lea Manor Sports Centre and High School, for example, four UF2000s are used to monitor the four LPHW circuits fed from the central boiler house. The LPHW energy supplied for the school heating, hot water services heating, sports centre heating and pool heating are all individually metered and the information used to apportion the overall energy bill to individual areas.
