Large-diameter ultrasonic heat meter with dual cold and hot metering, low power consumption, high precision, MBus/RS485/GPRS interface, and is the mainstream meter for heating pipelines and air conditioning systems. It has a wide range of uses.
Applicable:
heat metering at the entrance of buildings and areas for centralized heating and cold/heat energy metering for central air conditioning systems. It can be combined with a temperature controller remote control valve, data collector, concentrator, and management software to build a "Heat Metering Management System Based on On-Off Time Area Method" and a "He Metering Management System Based on Temperature Area Method" to achieve smart heating and remote management.
Product Application:
It is used to measure the actual heat energy consumption urban heating main pipelines, building heating main pipelines, and the cold and heat energy consumption of the main pipeline of the central air conditioning system, etc.
Applicable Standards CJ128-2007 "Heat Meter" Industry Standard, GB/T 32224-2015 "at Meter" National Standard, JJG225-2001 "Thermal Energy Meter" Inspection Procedure;
