Calorio 150

Product at a glance

Static heat and cooling meter

The Calorio 150 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 consists of the fluid oscillator flow sensor, the integrator battery or mains powered, and a pair of temperature sensors. Consumption values can easily be read over the display or various data interfaces like optical probe, M-Bus, LON, BACnet, Modbus, GSM and so on. The Calorio 150 integrator is suitable for connecting Pt 500 or Pt 100 temperature sensor pairs with 2 or 4-conducting wire techniques. Volume inputs can be combined with mechanical, magnetic-inductive, ultrasonic or fluidic oscillators flow sensors with a maximum nominal flow rate of 10'000 m3/h. The factor of the pulse value is defined in the flow meter unit. The volume input value is defined when the unit is produced. The pulse value can be modified one single time by means of the push button. The additional pulse inputs allow the connection of hot water, cold water, gas, oil and electricity meters.
