Product details
1、 Overview:
The Jingyuan small caliber heat meter is an integrated heat meter composed of a flow sensor, a paired temperature sensor, and a calculator. The flow sensor converts the impeller rotation signal into an electrical pulse signal, and the calculator accumulates the measurement of the water flow passing through by recording the number of pulses. The temperature of the inlet and outlet water is measured by a paired temperature sensor and transmitted to the calculator. The calculator can calculate the actual heat (cooling) consumed (absorbed) by the heating system based on the temperature at the system inlet and outlet, water flow rate and flow time, and water enthalpy value. It is suitable for household heat (cooling) metering projects.
Product compliantGB/T32224-2015According to the standard of "heat meter", it complies withJJG225-2001Requirements for the Verification Regulations of Thermal Energy Meters. The quality management system of this product complies withGB/T 19001-2015Management requirements.
