Two pulse outputs/inputs in the standard version.
Operated using a single button located under the LCD display.
Battery power supply with a possibility of a power network supply.
The option of installing the INVONIC H heat meter as the compact or split version (cable length 1.2 m)
• Total immunity to external EM fields.
Price from € 195,00 a 1.305,00
Variable depending on the configuration
Invonic H is a modern and precise heat and cooling meter utilising an ultrasoundflow transducer to guarantee high measurement precision for long term operation,regardless of the installation orientation. The heat meter has a modular structure,allowing a choice of optional features, such as communication module, powersupply type, and alternative temperature sensors. A robust brass flow transducer isavailable in versions with a threaded or flanged connection, for use with the PN16or PN25 pressure ranges. Heat meter indications are entirely unaffected by externalmagnetic fields.

Invonic H can be used in Heating/cooling systems in residential, office and industrial buildings, where theheating/cooling medium is water or water glycol solutions at temperatures up to130°C. The flow transducer can be disconnected from the calculator, which allowsinstallation in difficult locations and facilitates reading indications from the display.The heat meter may be installed in any working orientation and does not require theuse of straight sections upstream or downstream of the flow transducer. Remotereading of heating and cooling energy indications can be carried out by cableor wirelessly, and can be integrated with data reading and building automationsystems.
