Ultrasonic heat meter
Ultrasonic cold and heat meter is an smart heat metering device, it also named BTU meter,which realizes accurate measurement of cold and heat.It fully conforms to CJ128-2007 standard and JJG225-2001 national standard verification regulation.
What is the Ultrasonic heat meter
Ultrasonic heat meter is a precision instrument used for measuring thermal energy consumption in heating and cooling systems. It operates based on ultrasonic transit-time technology, where ultrasonic signals are sent through the medium to calculate the flow rate of the heat-transfer fluid. By integrating flow rate measurements with temperature readings from supply and return pipes, the meter accurately determines the amount of heat energy consumed.
Where is the Ultrasonic heat meter usded for
Ultrasonic heat meters provide excellent long-term stability and accuracy, making them ideal for residential, commercial, and industrial applications.These meters are widely used in district heating and cooling systems, HVAC applications, and energy metering projects. With their high precision and durability, ultrasonic heat meters help optimize energy consumption, reduce costs, and support sustainable energy solutions.
Ultrasonic heat meter Features:
Transducer: As the main signal generating part of the ultrasonic heat meter, it adopts imported piezoelectric ceramic chips, with stable performance and good consistency, to ensure that the ultrasonic heat meter can achieve high-precision measurement.
Temperature sensor: PT1000 high-precision platinum resistance is adopted and equipped with precision measuring circuit to ensure high-precision temperature measurement.
Self-diagnosis function: in the process of stable operation of the ultrasonic heat meter, if the communication is abnormal, the power is insufficient, or the system will display the corresponding code, and the system will automatically save the data and wait for the recovery after troubleshooting.
Remote transmission and centralized control function: with M-BUS and 485 interfaces, it can realize data remote transmission and centralized control
Can be hung in four directions, convenient for reading and easy to operate.
Easy to install and has the functions of dustproof, moisture-proof, waterproof, anti-disassembly and man-made damage.
