understanding thermal metering

Thermal energy metering has been utilized in Europe for decades, but has only recently become prevalent in Canada. Measurement Canada is now in the process of regulating thermal metering for the Canadian market. QMC can expertly provide metering to meet these upcoming standards. 

Further, we are an accredited testing and verification service provider.  In order to attain better understanding thermal metering, customers require better expertise and their utilities require better transparency.
