一、Product Summary

Dear users, thank you for using our electromechanical separation heat meter. Please read this instruction manual carefully before using it, so that you can easily use our products.

This product belongs to an intelligent heat meter. Its function is to calculate the heat consumed by the user by measuring the flow rate of hot water flowing through the user and the temperature difference between inlet and return water. This heat value will be used as an important reference basis for heating charges to participate in the accounting of heating costs. It is composed of flow sensor, paired temperature sensor and calculator, and its structure is simple, compact and reliable.

 

二、Working Principle

A pair of temperature 1 sensors are respectively mounted on an upward pipe and a downward pipe passing through a heat-carrying fluid, The flowmeter is installed on the fluid inlet or return line (the flowmeter is installed in different positions, The final measurement results are also different). The flowmeter sends out pulse signals proportional to the flow rate, a pair of temperature sensors give analog signals indicating the temperature level, and the totalizer collects signals from the flow rate and temperature sensors and calculates the heat obtained by the heat exchange system by using the calculation formula.

四、Performance characteristics

1. This product uses a high-precision time measuring core to ensure high accuracy and stability of measurement

2. It is equipped with Hall flow sensor, and the liquid flowing through the meter is measured by pulse inside the meter, which will not produce any mechanical wear and has lower maintenance cost

3. It can be installed horizontally or vertically. During installation, it can be installed on the water inlet pipe or return pipe according to different needs of users (the installation position needs to be selected in advance, and the default is water inlet installation)

4. M-BUS, RS485, GPRS, NBIOT and LORAWAN modules can be added according to different needs of users to realize remote automatic meter reading function, which is convenient for centralized management (pre-selected)
