Smart Huizhong Ultrasonic Heat Meter with MID Quality
Smart Huizhong Ultrasonic Heat Meter with MID Quality
CRL-H series DN15mm~DN40mm
Applications:
CRL-H ultrasonic heat meter is individual household-use Ultrasonic heat meter.The meter is used for measuring the energy consumption in district heating/cooling application for billing purposes.
Features
1. The CRL-H ultrasonic heat meter is high in measuring accuracy and steadiness.
2. It is long in service life for it has no mechanical moving parts and no wearing nuisance.
3. The CRL-H ultrasonic heat meter is low in maintenance cost.It operates with micropower consumption technology.(One battery can sustain its continuous working for a period of over 10 years).
4. It supports photoelectic interface,RS-485 and M-BUS output interfaces.The possibility of realizing remote data reading facilitates therefore centralized control and management by consumers.
5. The CRL-H ultrasonic heat meter operates with ultrasonic flow measuring technology.
6. Temperature range from 4℃ to 95℃,it is a dual-purpose meter for either heat or cold measurement.
7.The meter is in compliance with the standard CJ 128-2007 "Heat Meter"—a Chinese trade standard set for Urban construction sector.
