The Superstatic 440 is a static heat or cooling meter according to standard EN1434 class 2 based on the fluid oscillation principle, covering a wide range of flows for all applications in district heating and cooling or building automation. The fluid oscillation principle guarantees a high stability and repeatability for a reliable and precise measurement of flow and thermal energy.


The heating and cooling meter Superstatic 440 meter consists of the fluid oscillator flow sensor, the integrator Supercal 531, battery or mains powered, and a pair of temperature sensors Sontex 460. Consumption values can easily be read over the display or various data interfaces like radio, M-Bus, optical probe, GSM and so on.

Temperature sensor pair

The temperature sensors and the integrator Supercal 531 in combination with the Superstatic flow sensor are available as Pt 500 or Pt100 version. The temperature sensors are paired. They are always supplied in pairs and must not be separated, extended or shortened. In the case of temperature sensor pairs with a cable longer than 3 m, we recommend the exclusive use of screened temperature sensor pairs.

Measurement technique

The integrator Supercal 531 with mains power supply records every 3 seconds the supply and the return temperature, with battery power every 20 seconds (D-type battery). The recording of the flow is dependent of the pulse value of the flow sensor and is constantly updated. With the mean flow rate, the temperature difference and the heat coefficient the energy is calculated of the captured medium and displayed on the 8- digit LCD display.
