YG-EAS





Application: Before mount the heat firstly install this YG-EAS in pipeline. It will help to avoid damage meter during build apartment and rubbish in pipeline plug up the heat meter. Only need turn-on the cover and mount heat on the body of YG-EAS when want to assemble heat meters.

Measuring Features:
Water will release heat if temperature decreases. Released heat is ratable with temperature difference and flow volume through meter. Flow volume signal comes from flow sensor, temerature difference comes from temperature sensor pair, as result the calculator will calculate heat according to the flowing volume and temperature difference.

Water pressure: ≤1.6Mpa
Measuring accuracy: Class 2
The max tolerance is shown in the curve below:
E=±(3+4Δθmin/Δθ+0.02qp/q)%
Therein,Δθmin means the minimum temperature difference, and Δθthe actual temperature difference.
