Heat Metering Technologies
Selecting the correct heat metering technology - were here to help!
It can be difficult to know which technology is best suited for your application, we have laid out the options of heat metering technology available. We also offer CIBSE approved CPDs - you can read more below!
Here are the options of meters that are suitable for use in the UK. Depending on what you require from your meter you can choose from the below technologies.
Superstatic
Principle: The main part of the flow passes through a Venturi nozzle in the pipe, creating the differential pressure to bypass the other part of the flow through the fluid oscillator. pressure oscillations are converted into an electric signal by a piezo sensor and detected by the integrator
Approval Rating: Class 2 MID
Billing Approved: Yes
RHI Approved: Yes
Power Supply: Battery / Mains
Mechanical:
Principle: A traditional pulsed mechanical water meter supplied with a separate integrator for energy calculation
Approval Rating: Class 3 MID (due to the Class 3 rating on the mechanical meter)
Billing Approved: Not for non-domestic
RHI Approved: Not for non-domestic
Power Supply: Battery / Mains
Ultrasonic:
Principle: working on the Doppler frequency sensors installed upstream and downstream picking up flow and disturbance along the pipe and compensated by a temperature sensor.
Approval Rating: Class 2 MID
Billing Approved: Yes
RHI Approved: Yes
Power Supply: Battery / Mains
UK Heat Meter Regulations
•For any non-domestic application where the meter will be used for Billing (including sub-metering) the meter must be MID Class 2 approved - Class 3 is not suitable.
•Class 3 meters can be used for domestic billing
•Heat meters used for non-domestic RHI (Renewable Heat Incentive) must also comply with accuracy class 2 or better of the Measuring instrument directive(MID)
