Fluidic oscillation compact heat / cooling meter
The Calorio 110 is an autonomous compact thermal energy meter consisting of a flow meter a detachable integrator with a wide range of communications options and a pair of temperature sensors. It’s used in home automation, local and district heating /cooling systems to measure the consumption of heating or /and cooling energy for individual billing. The Calorio 110 is designed on the basis of the proven fluid oscillation principle. Thanks to the use of a static flow sensor,this heat meter does not have any moving parts and thus no wear. The fluid oscillation principle guarantees a high stability and repeatability for a reliable and precise measurement of flow and thermal energy. It is optimally suited for glycol and other mixtures. It’s built for flows of qp 1.5 m3/h and qp 2.5 m3/h and measures the temperature within the range of 0°C to 110°C. Through its two additional optional pulse inputs, it is possible to connect, e.g., two water meters (hot and cold) and read their values remotely via the heat meter. The Calorio 110 meets the requirements of the European Measuring Instruments Directive (MID) 2014/32/EU, standard EN 1434 class 2 and the RED 2014/53/EU.
