Overview
HUM1000, a large-bore ultrasonic heat meter, measures thermal energy carried by liquids or steam. It gauges fluid velocity via ultrasonic principles and computes heat output based on the temperature differential between the inlet and outlet pipes. Widely applied in district heating networks, industrial manufacturing and energy management systems, HUM1000 delivers accurate energy measurement and facilitates efficient energy consumption control.
Features
·Adopts the ultrasonic measurement principle,, featuring zero mechanical friction and long service life.
·Designed for large-caliber pipelines, widely applied in central heating and district cooling systems.
·Equipped with communication interfaces to support remote monitoring and data collection.
·Powered from a lithium battery. Depending on use and setup, the lifetime is up to 10 years.
·Minimal pressure drop reduces pipeline operation energy consumption effectively.
·Complete self-diagnosis fault function for convenient daily management.
