Description
The MV311 thermal energy meter is designed for the thermal balance or the billing of the thermal energy produced, according to the EN1434 standard and the MI-004 2014/32/EU approval. The MI-004 approval requires factory programming of the main parameters. Equipped with two types of meter inputs, it can be connected to mechanical meters, electromagnetic flow meters, ultrasonic flow meters. Its sensor power supply can power the MV800 or CS3795 type flow meters that we can offer.
It has pulse or 4-20 mA inputs for flow measurement and Pt 100/500/1000 temperature inputs.
