Battery- or mains-powered Superstatic heat and cooling meters (EN1434 Class 2) are unique, using a static measurement principle, hence without moving parts. Available in a wide range of flow rates, they are used in building technology and automation and in district heating. The fluidic oscillator principle used, where only the liquid flowing through moves, guarantees the precision and stability of measurements for reliable flow and energy readings. All heat meters can also be used as cooling meters, mounted either horizontally or vertically. Superstatic heat meters also work perfectly if the water is dirty or if magnetite deposits build up in the pipes. The fluidic oscillator principle was developed by NASA and refined by Sontex for measurement purposes.
All our static heat meters meet the requirements of the European Measuring Instruments Directive MID 2014/32/EU and standard EN 1434 class 2. They have also been type approved by PTB Germany for cooling applications and can be ordered for heating, cooling or mixed applications with the according approvals.
Fluidic oscillation heat meters for many flow rates
Based on the static measurement principle, the Superstatic 440 provides solutions for low to very high flow rates (qp 1.5 – 1500 m3/h). One important element is the multifunctional calculator that can be equipped with various communication interfaces. The removable measuring head allows efficient re-calibration.
Dismantling and assembly costs are significantly reduced because only the measuring head needs to be changed. Complex interventions in the pipe system are unnecessary. The Superstatic 440 measuring head is the same for any flow rate, thus simplifying planning. The use of high-quality corrosion resistant materials ensures the measurements stability and working reliability during several calibration periods. In the German district heating association AGFW-Wärmezähler Prüfprogramm IV, the static heat meters with nominal flows qp 1.0 m³/h and qp 3.5 m³/h received the top grade of 5 stars for measurement precision and stability. Sontex provides many installation lengths according to EN1434, various materials such as ductile cast iron and can thus be used in a great variety of uses.
The Superstatic 440 is completed by a multifunctional calculator. This can be battery- or mains-powered and offers the entire range of Sontex communication modules. This guarantees an extremely wide range of uses and simple integration in every district and proximity heating network or building management system.
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.
The sturdy compact heat meter with the fluidic oscillation principle.
The Superstatic 749 fluidic oscillation meter is the compact version of the Superstatic 440 that has been used for many years and is very popular. The Superstatic 749 is even more compact and seamlessly fits in the Superstatic product portfolio. It is designed for less complex uses of static heat and cooling meters where fewer functions are needed than with the Superstatic 440. It has a removable compact calculator with communication modules and can be easily integrated into district heating or a building management system.
The Superstatic 749 is available for flow rates of qp 0.6; qp 1.5; qp 2.5 m³/h and in lengths of 110 mm, 130 mm and 190 mm.
