With the rapid development of the IOT in the "smart city" heating system application of ultrasonic intelligent heat meter for high-precision, low-loss ultrasonic flow transducer demand is increasingly obvious. In order to further improve the measurement accuracy of ultrasonic smart heat meters, AUDIOWELL has developed a new generation of flow transducers specifically designed for ultrasonic heat meter applications - the High Temperature Ultrasonic Flow Transducer.
The "smart heating" trend:
Ultrasonic measurement solution is the mainstream measurement solution for smart heat meters
In order to improve energy utilization and achieve sustainable urban development, "smart heating" has become an important part of building a "smart city". The application of technically mature ultrasonic measurement solutions is one of the key elements in realizing high-precision, low-loss heat metering and establishing a "smart heating" system, which is the core technology route for heat metering towards green development.
Ultrasonic measurement program as the core of the heat meter in the promotion of sub-household metering, the realization of the heat supply balance of the "smart heating" construction process has played an irreplaceable role. Ultrasonic heat meter is mainly used for measuring and displaying the heating capacity of family households and buildings. When the hot water passes through the ultrasonic heat meter, the internal ultrasonic flow sensor derives the flow rate through the difference of the propagation time of the ultrasonic waves in the downstream and go against the trend, and then sends out a flow signal after obtaining the flow rate, and then combines it with the temperature value measured by the temperature sensor, so that it can be comprehensively calculated to arrive at the value of the consumed heat.
High Temperature Ultrasonic Flow Transducer:
High-precision flow transducer with high temperature resistance of 240°C
AUDIOWELL High Temperature Ultrasonic Flow Transducer is a liquid medium ultrasonic transducer, using high pressure resistant stainless steel and ceramic materials, highly sealed design, can be in direct contact with the liquid. These processes make it avoid the problem of unstable pressure and heat resistance, making the performance more stable, reducing the interference of environmental factors on signal output and reception, and effectively improving the response sensitivity of the product. Assembling High Temperature Ultrasonic Flow Transducer in ultrasonic heat meter can effectively improve the measurement accuracy of ultrasonic heat meter. In addition, the product is suitable for liquid flow measurement and can be used as a liquid flow sensor.
Accurate ultrasonic measurement technology
High Temperature Ultrasonic Flow Transducer detects the flow rate by means of ultrasonic measurement technology, and then derives the flow rate magnitude from the flow rate. There are no other moving parts inside the ultrasonic heat meter using it, and no eddy currents are generated. The transducer measurement does not affect the fluid movement flow rate, direction, etc., low pressure loss, so that the instrument measurement results are more accurate.
High temperature resistance up to 240°C
AUDIOWELL High Temperature Ultrasonic Flow Transducers are available in ceramic and stainless steel housings. They can withstand temperatures up to 240°C for ceramic housing and 120°C for stainless steel housing. The transducer does not affect the measurement accuracy even when used in continuously boiling hot water, guaranteeing that the ultrasonic heat meter outputs highly accurate measurement results.
Withstand 2.5MPa pressure
Compared with plastic housing material, the stainless steel and ceramic housing materials used in the AUDIOWELL High Temperature Ultrasonic Flow Transducers are more rigid, and the products can withstand 2.5MPa pressure for a long period of time, which is much higher than similar transducers on the market with a pressure resistance of 1MPa.
Advantages
Low voltage drive and good consistency
AUDIOWELL High Temperature Ultrasonic Flow Transducers drive voltage is 5Vp-p, the product drive voltage is low, and meet the testing requirements of Europe and the United States, good consistency.
Excellent weather resistance
A variety of tests show that this product is resistant to humidity, cold and hot shock, vibration, etc. The overall weather resistance is good, and it can meet the requirements of high-temperature water metering for industrial equipment with high reliability.
Wide range of applications
The probe diameter of the High Temperature Ultrasonic Flow Transducer is 16.8mm, which matches the assembly requirements of conventional ultrasonic heat meters and ultrasonic water meters, and is suitable for use in various water metering instruments. The small size of the product can be assembled in the internal application of industrial equipment pipelines, providing technical support for high-precision measurement of water in industrial equipment.
