Calorio 500

Product at a glance

Static heat and cooling meter

The Calorio 500 is Secure’s next-generation thermal energy meter, succeeding the well-known Calorio 150. This new series is characterised by user-friendly modularity in design and fully meets customer-specific requirements, including simplified system integration, tariff and data logger functions, universal data transfer and connection to system processors.

It is suited as a heat or cooling meter. According to standard EN1434, class 2 is based on the fluid oscillation principle. It covers a wide range of flows for all industrial and district heating and cooling applications or building automation applications. It guarantees high stability and repeatability for reliable and precise flow and thermal energy measurements.

The Calorio 500 design aims for a high degree of flexibility while keeping future standards in mind. The additional pulse inputs allow the connection of hot or cold water, gas, oil, and electricity meters. In addition to its extensive range of data communication options and flexibility for collecting and recording dynamic plant data.
