The valve controlled ultrasonic heat meter consists of four parts: an ultrasonic flow sensor, a paired temperature sensor, a calculator, and a valve control unit. Its working principle is to calculate and display the cooling or heat obtained by the user from the heat exchange system through a calculator based on the flow rate provided by the ultrasonic flow sensor and the temperature signal of the supply and return water provided by the paired temperature sensor, as well as the time the water flow passes through; Integrated with an intelligent valve control unit, it facilitates efficient and convenient remote monitoring and control management for management departments.
Main functions and features:
The flow sensor is designed using the ultrasonic principle and uses high-quality piezoelectric ceramic transducers, ensuring high accuracy and stability; There are no mechanical moving parts, no wear, less susceptible to adverse water quality, and low maintenance costs. It has the advantages of stable operation, accurate measurement, and long service life.
Adopting professional chips as microprocessors, advanced low-power design, longer service life, static current less than 15uA, and strong anti-interference performance.
The temperature sensor adopts high-precision precision paired PT1000, which has high measurement accuracy, good stability, and fast response.
Equipped with optoelectronic and various communication interfaces, it can directly use infrared reading and writing heads to read and write data, and can also be equipped with remote communication methods such as MBUS, RS485, LoRaWan, etc.
The LCD menu displays information such as heat, cooling capacity, flow rate, volume, inlet and outlet water temperature, temperature difference, power, time, aperture, etc., including user mode menu, detection mode menu, data information mode menu, and error information mode menu.
Data storage function: 38 months of historical data storage.
High torque and low power electric valve, with fast opening and closing, flexible opening and closing, long service life, safety and reliability.
Valve self-cleaning function: It can automatically open and close the valve periodically and at a fixed time, removing internal scale formed due to long-term inactivity, and avoiding the phenomenon of valve failure to open and close.
Remote intelligent monitoring: Through remote communication, management departments can monitor user usage, supply and return water temperature, flow rate, and changes in these parameters, thereby providing basic data reference for the efficient operation of the entire heating or cooling system.
Remote intelligent control: Through wired or wireless communication, the opening and closing of valves can be remotely controlled, facilitating the daily management of management departments.
Place of use: heating or cooling systems.
In summary, this ultrasonic valve controlled heat meter achieves remote meter reading, monitoring, and control through remote communication technology, with features such as remote meter reading, intelligent monitoring, and on/off valve control. Its emergence provides a strong guarantee for the accurate measurement, remote monitoring, and remote control of heating or cooling systems, and provides a basic reference basis for the efficient operation of management departments, greatly facilitating their daily management.
