Thermal Heat flow metering utilising Clamp-On Ultrasonic water measurement provides cost-effective, minimal disruption, installation and maintenance solution for Campus District Heating Systems
<---PDF Version
Kings College - London heats its campus sites via a number of boiler houses, generating thermal energy for distribution to individual buildings via LTHW (Low Temperature Hot Water) networks.
A pilot system of new meters was installed 12 months ago to identify the thermal energy use of individual buildings, facilitate their management as Energy Cost Centres and provide informa-tion for Building Energy Labelling in line with European Direc-tives.
The new meter installations on the Guys campus, which represent circa 10% of the university is currently being manually read. However, the plan is for the meters to be read automatically via the university's BEMs system, to provide continuously updated information for Monitoring and Targeting
including benchmark comparisons with energy consumption norms for the university sector.
Having considered various measurement alternatives Clamp-On Ultrasonic meters were selected due to the installation and maintenance/service benefits associated with the non-invasive technology including low cost

Micronics U2000 Clamp-on, Ultrasonic flow meters combined with CalecST heat calculators were chosen because they are non-invasive i.e. they can be installed without the need to cut into existing pipework.
The clear benefits are:
• Significantly lower installations costs (40% Less) than an alternative in–line meter installation!
• Less disruption than installing an alternative in-line meter.
• Avoidance of residual venting problems associated with system drain down.
