Shetland Heat Energy & Power Ltd (SHEAP) is one of the largest and longest running district heat networks in operation in Scotland. The scheme uses waste heat from industrial processes to heat approximately 1300 domestic properties and commercial and public buildings around Lerwick including schools, care homes, the leisure centre and the Gilbert Bain Hospital.
SHEAP chose Kamstrup ultrasonic heat meters with radio communication to ensure residents receive accurate bills and to allow for the meters to be read when required without having to access properties. SHEAP periodically send heat meters away for calibration tests to check accuracy and reliability therefore ensuring value of money for residents and businesses connected to the heat network.
One of the heat meters sent away for calibration testing this year was manufactured in the year 2001 therefore has been in service for 23 years and 123,038 kWh. When tested in Kamstrup’s accredited facility, it proved to be within 1.34% at the nominal flow rate, 1.05% at 10% of the nominal flow rate and 1.32% at 1% of the nominal flow rate.
Kamstrup heat meters are renowned for accuracy, durability and reliability which is backed up by the “Heat sample test report” released annually. This years results can be reviewed here.
Some of the ultrasonic flow sensors tested are between 13 and 26 years old and still measuring accurately.
When selecting energy meters for your next project or selecting a heat meter for you HIU, choose one with proven accuracy to ensure that your residents are paying exactly what they should be for their energy consumption.
“Kamstrup Heat Meters have served our metering needs reliably for over 25 years and we will continue using them into the future as our network expands” Robert Brandie, Shetland Heat Energy And Power
