Overview
Execution standard: Industry standard for urban construction in the People's Republic of China, "Heat Meter" CJ128-2007
Product Details
HDIL ultrasonic calorimeter
Technical Parameter
The ultrasonic heat meter is composed of a flow sensor, a paired temperature sensor, and a calculator, and has the characteristics of compact structure and easy installation. This product uses high-quality ceramic transducers to ensure high accuracy and stability; No mechanical movement, no wear and tear, not easily affected by poor water quality, and low maintenance costs; Can be installed horizontally or vertically, and can be installed on the inlet or return pipeline according to different user needs (pre selected); RS485 interfaces can be added according to different user needs to achieve remote meter reading functions for centralized management.

Operating instructions
After long pressing the button for 3 seconds, the displayed menu will start switching between A1-A2-A3. When released, it will enter the corresponding menu, and when the button is briefly pressed, it will scroll through the displayed content under the same menu.
2. Main display menu A1: Eight display contents: cumulative heat (kW · h), instantaneous heat (kW), inlet and outlet water temperature (℃), inlet and outlet water temperature difference (℃), cumulative flow rate (m3), instantaneous flow rate (m3/h), cumulative operating time (h), and cumulative alarm time (h).
3. Main display menu A2: Five display contents: current date, current time, factory number (14 digits in total, H represents high position, L represents low position), display test, motherboard batch.
4. Main display menu A3: The monthly heat consumption and flow values for the first 24 months are automatically displayed alternately between months and values.
5. Fault alarm menu: low battery warning and other automatic fault diagnosis functions.
