ELF - COMPACT HEAT METER WITH ROTATING FLOW TRANSDUCER (DN15-20) – WITH FLOW TRANSDUCER TYPE JS90-NI*

Precise and reliable heat meter, equipped with high class heat calculator and flow transducer of class 2, with electronic detection of rotor rotation and archiving many of data readings. It is distinguished by its modern design. Heat meter for measuring the consumption of heat energy drawn from heat networks by small residential or office buildings. Heating factor with a temperature up to 90 °C (105 °C**) and maximum working pressure up to 16 bar (PN16). Suitable for installation in the horizontal hoses (pipelines) with the counter directed upwards (H), or in vertical hoses (V).

**) when installing the heat meter on a return pipee
