Unequalled quality
and precision

Thermal Energy meters from Sontex:
flexible and reliable.

Super convincing product line

Superstatic and Supercal thermal energy meters are available for many flow rates. They are used in building technology and automation and in heating networks.

The Superstatic and Supercal families have proven themselves thousands of times in thermal measurement and are unrivaled in cooling applications. Measurements are made using flow sensors and temperature probes, and the associated calculators calculate energy consumption. They can be mounted vertically or horizontally and can be installed in supply or return pipe.

A wide range of communication modules is available.

The thermal energy meters of the Superstatic and Supercal family are characterized by a high measurement accuracy and can also be used with over 90 different cooling liquids already integrated; others on request.

Piezoelectric sensor

The thermal energy meters work according to the fluidic oscillation principle: Due to the specific geometry inside the meter, a stable oscillation is generated, the frequency of which is directly proportional to the flow rate. The piezoelectric sensor measures this frequency via pressure differences and thus calculates the volume.

This principle, developed by the NASA over 50 years ago, was brought to market maturity by Sontex and is now used in several hundred thousand thermal energy meters worldwide. One of the advantages is that it can also be used for large pipe diameters. The Superstatic and Supercal meet the Standard EN1434 Class 2 and Class 3 for the mechanical Supercal 739.

icon zuverlaessigkeit
As the thermal energy meters operate without moving parts there is no need for maintenance. They operate with the highest precision and do not need to be recalibrated for over 10 years
icon zertifizierung
The thermal energy meters meet the requirements of the European directives of MID-2014 / 32 / EU and are unsurpassed in accuracy. They are country specific approved for cold applications.
icon unempfindlichkeit
Since the devices are impervious to contamination and magnetite deposits, they are suitable for challenging applications. Small air bubbles also have no effect on measurement precision.

Product range
Sontex offers two static energy meter product groups: Supercal 5S for high-end applications, and Superstatic 749 and 789 as compact heat meters. These can be used in a wide range of installation types. Each group has an identical calculator, which reduces training requirements to an absolute minimum.
icon energiemanagement
Energy management
Contrary to ultrasound meters, a Superstatic or Supercal meter measures the flow constantly. To extend battery life, data are only refreshed as needed.
icon lange lebensdauer
Long lifespan
With their static measurement process involving no moving parts, thermal energy meters are practically free of wear, are maintenance-free and enjoy a long lifespan.
