A new innovation from Sontex is the Superstatic 789 Heat Meter. The biggest change in design from previous models is the use of a composite Meter body instead of Brass. The lightweight construction and lower costs add to the list of benefits that all Superstatic Meters carry. The 789s use the Fluid Oscillation Measuring Principle and have been tested to meet the requirements for MID Class 2. Therefore, the 789 Meters can be used with both Domestic and Commercial RHI Installations and for Billing Applications as well. Systems with glycol content are also not a problem as the 789s can be calibrated to measure accurately in such systems.
As per the other ranges of compact Meters that Sontex offers, the 789 has one of the temperature sensors mounted on the Meter Body in order to save on space and installation costs. The Display can be mounted on a wall nearby using the bracket provided but the general use for these Meters would have the Display mounted on the body itself.
The Superstatic 789 meters are all Battery Powered as standard and the batteries are fully replaceable without having to install a new meter. The lifespan of these batteries are available in options of 6 years and 12 years. Three sizes of the 789 are available including QP1.5 15mm, QP1.5 20mm and QP2.5 20mm. The QP Reference relates to the nominal flow rate in m3/hr that each Meter can measure up to.
