ZY split mechanical heat meter adopts a number of patented technology unique to Weihai zhenyu intelligence and technology Co., Ltd in domestic and innovatively designs the flow sensor as dismountable split structure and solves many deficiencies existing in the conventional integral heat meter.
Features:
1. Split installation
2. Can be dismounted for cleaning and maintenance
3. Convenient for verifying and calibrating again after usage
4. Good installation adaptability
5. Other technical characters
(1) flow sensor adopts no magnetic sensor of oscillation damping circuit principle, can effectively avoid rust adsorption
(2) heat meter sensor is multiple stream structure with high measurement precision
(3) low power consumption between 15 to 30μA, 3.6V/3.8Ah large capacity battery
(4) support RS485, M-bus and various remote collection methods
(5) MSP430 specialized chip
(6) The calculator master chip features storage and power-down memory function with storage of 18 months of heat usage data
