Chapter 7 of the government’s RHI announcement says

Measuring steam

Accurate measurement of steam is possible but represents particular challenges. In particular, it requires a higher degree of accuracy and entails higher costs. Where boilers are used to produce steam rather than hot water, the regulations will require measuring equipment that accurately measures flow rate, temperature and pressure. Participants must provide the appropriate metered steam figure to Ofgem having deducted any condensate returned to the boiler or steam used for ineligible purposes. This could be achieved by metering these items separately.

Guidance on choice of appropriate steam measuring equipment and installation and maintenance can be found in the Good Practice Guide (GPG018) available from the Carbon Trust.
