On installation the meters will need to be properly calibrated. Periodic recalibration may also be required.
Chapter 7 of the government’s RHI announcement says
Maintenance requirements for meters
The RHI regulations will require that heat meters used to claim RHI payments are installed in accordance with the manufacturer’s instructions. Where meters are supplied as a package, comprising a flow meter, a pair of temperature sensors and a computer/integrator, they should be recalibrated or replaced in accordance with the manufacturer’s instructions.
For solar thermal, where appropriate, heat meters will need to be calibrated at the point of installation for any water/ethylene glycol mixture in the collector.
