Superstatic 789

Superstatic 789


Made of fibre composite, the new Sontex Superstatic 789 compact heat meter is sturdy and light. It is known for its precision and reliability thanks to the static measurement principle.

The new Sontex Superstatic 789 compact heat meter of fibre composite for heating/cooling applications is the logical evolution of the use of the principle of fluidic oscillation which, thanks to its accuracy and reliability of measurement, is a reference in the measuring of thermal energy.

All the benefits and features of fluidic oscillation were adapted and integrated into a compact shape for a flow of qp 1.5 – 2.5 m³/h. While its total weight has been reduced by half, it retains its shape despite temperature differences and devices have been introduced to guarantee mechanical resistance.

Based on the latest piezo technology, the new flow sensor, which is also suitable for glycol mixtures, is equipped with a detachable multifunction integrator with a wide range of communication options. This covers many applications and ensures its trouble-free integration into a district heating network or a building management system.
