Thermal heating metering and selection solutions

In order to comprehensively improve the level of heating and achieve energy conservation and emission reduction, the "steam to water" project has been fully launched. The heat source of heating has been changed from steam to high-temperature water, significantly improving the heating effect of residents, greatly saving energy consumption and reducing emissions. High temperature water pipe network has the advantages of energy conservation, stability, safety, and efficiency. The accurate measurement of high-temperature water has become an important lever for the management and efficiency of heating companies.

【Solution】

In the initial stage, imported ultrasonic flow meters were mainly used for large-diameter high-temperature water measurement instruments, which were characterized by good quality, stable performance, high cost, long delivery time, and weak service. With the increasing maturity of domestic ultrasonic technology, Weifang Aobo Instrument has increased research and development investment, overcome difficulties, and successfully developed a high-end product "dual channel ultrasonic flow meter" that can compete with imported brands. Successfully passed the appraisal of the National Water High Flow Measurement Station and the Provincial Institute of Metrology, and all indicators can meet relevant national standards and fully adapt to the heating site situation in China.

This dual channel ultrasonic flowmeter, which is "benchmarking and surpassing, replacing imports," has obtained 1 invention patent certificate, 6 utility model patent certificates, and 1 computer software copyright registration certificate; Widely used in industries such as thermoelectric, thermal, and heating, it has received unanimous praise and created good economic and social benefits.

The advantages of the dual channel ultrasonic flowmeter produced by Weifang Aobo Instrument are as follows:

1. Dual channel, full pass pipe section, non reducing, split installation.

2. No interruption of current for online maintenance and replacement of probes.

3. High dynamic response, the instrument has no difference between calibration mode and usage mode. During normal use, the sampling frequency of flow rate per second is not less than 40-200 times, with strong resistance to bubbles and interference.

4. Equipped with simulation function.

5. Wall mounted converter: LCD display with backlight control, displaying parameters such as instantaneous flow rate and cumulative flow rate; Supports 2 standard current signal inputs; The instrument supports both 1 standard current signal output and 1 high-speed pulse signal output. AC220V and DC12V dual power supply. Equipped with RS485/232 communication interface and standard Modbus communication protocol.

6. Equipped with intelligent flow heat totalizer and temperature sensor, heat calculation can be carried out.

7. Select a GPRS data transmission module to upload on-site data to a remote meter reading platform for real-time monitoring and management of data;

8. Equipped with an IC card prepaid intelligent metering control system, achieving a "pay first, then use hot" mode, completely solving the problem of arrears.
