Canadian program created to approve thermal energy meters


Applications will soon be accepted on a regular basis by Measurement Canada for the approval of thermal energy meters – also known as BTU meters. A thermal energy meter measures energy from hydronic heating and cooling systems.

A recent pilot program tested a number of meters. The new program is based on that and will rely on other test facilities to do work on behalf of Measurements Canada. Currently, these facilities must be accredited to the International Organization for Standardization (ISO) standard or recognized bodies via the European Union (EU) or International Organization of Legal Metrology (OIML). A new bulletin will be coming soon that describes the process.

More options are being looked at for authorized test facilities and authorized service providers. The implementation of authorized test facilities is expected early in 2020. Authorized service providers will follow within the next year or two.

HRAI recommends to member companies interested in becoming an authorized test facility to consider accreditation to one of the international standards, cautioning against pursuing an alternate accreditation until Measurement Canada has defined what is acceptable.

Measurement Canada is an agency of Innovation, Science and Economic Development Canada. They are responsible for ensuring the accuracy of measuring instruments along with developing and enforcing the laws related to measurement accuracy.

Authorized service providers are expected to be the same as the existing requirements for authorized service providers who inspect scales and gas pumps.

Measurement Canada isn’t expected to roll out the alternate service delivery program immediately. Plans are to go into the field and inspect meter installations to appreciate the variety of circumstances in which they are used, reports HRAI.
