NYLL-CH Electromagnetic Heat Meter
The NYLL-CH series electromagnetic thermal energy meter is a measuring
meter for measuring the heat released by the heat fluid loaded in a
heat transfer system.It uses a high precision, high reliability of
the electromagnetic flow meter as a flow measurement, using a high
precision, high stability of the platinum thermal resistance to do
the temperature measurement, so that the thermal energy meter has a
very excellent measurement performance.It can be widely used in the
measurement of civil residential areas, office buildings,
enterprises and institutions of central heating, heating, air
conditioning and other heat.
