Supercal 531

The multi-functional integrator

The Supercal 531 multi-functional integrator features a modular concept. By using multi-functional technologies, it easily meets a variety of customer requirements. The integrator offers a choice of M-Bus, radio or SMS modules. It can also be upgraded with up to two retrofittable communication modules:

    • M-Bus module
    • M-Bus module with 2 relay outputs
    • BACnet MS/TP module
    • ModBus module
    • LON module
    • RS-232 module with 2 relay outputs
    • Relay module
    • Analogue module with 2 outputs 4…20 mA
    • Analogue module with 2 outputs 0…20 mA, 4…20 mA or 0…10 VDC
    • Combi module with RS-232,3 relay outputs, 4 freely programmable outputs 0…20 mA, 4…20 mA or 0…10 VDC

The Supercal 531 is supplied with a battery as standard. Other supply modules are available depending on the application.

Superstatic 440

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.

 

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.

 

Superstatic 749

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.
