High temperature resistance up to 240℃！High Temperature Flow Sensor: Ultrasonic Measurement Solution with High Accuracy and Low Loss for “Smart Heating”

With the rapid development of Internet technology, ultrasonic smart heat meters used in "smart city" heating systems have an increasingly obvious demand for high-precision, low-loss ultrasonic flow sensors. For further improvement of the measurement accuracy of ultrasonic smart heat meters, ADW which has been experienced in sensors, launch of a new generation of flow sensors specifically designed for ultrasonic heat meter applications -- High Temperature Flow Sensor.

The Improvement of “Smart Heating”:

Heat Meters with Ultrasonic Measurement Method has become Essential

To improve energy efficiency and achieve sustainable urban development, "Smart Heating" has become an important part utilization in a "Smart City". The ultrasonic measurement solution with well-experienced technology is used to achieve high-precision, low-heat loss meter. One of the key elements in establishing a "Smart Heating" system is the inevitable path for ‘Green Technology’ of heat supply meter.

Heat meters with ultrasonic measurement methods are the most important instrument whereas an irreplaceable role in the construction process of "Smart Heating" that promotes household measurement and achieves heat supply balance. This meter is mainly used to measure and display the heating heat supply of households and buildings. When hot water passes through the ultrasonic heat meter, the internal ultrasonic flow sensor calculates the flow rate through the difference in propagation time of ultrasonic waves in downstream and countercurrent flow. After obtaining the flow rate, the flow signal is sent out, and then combined with the temperature value measured by the temperature sensor, the consumed heat value can be calculated comprehensively.

High-temperature Flow Sensor:

High-precision Flow Sensor with High Temperature Resistance up to 240°C

ADW High-temperature Flow Sensor is a liquid medium ultrasonic sensor. It is made of high-pressure stainless steel, ceramics, and other materials. It has a highly sealed design and can be in direct contact with the liquid. At the same time, it avoids the problem of unstable voltage and heat resistance, making the product's performance more stable, reducing the interference of environmental factors on the product's output and receiving signals, and effectively improving the product's response sensitivity. Application in ultrasonic heat meters can effectively improve the measurement accuracy of the meter. The product is also suitable for liquid flow measurement and can be used as a liquid flow sensor

Precise Ultrasonic Measurement Technology

the High-temperature Flow Sensor mainly detects the flow rate through ultrasonic measurement technology to obtain the flow rate. The application of this product’s ultrasonic heat meter has no other moving parts inside, and does not produce eddy current, so the sensor does not affect the flow speed, direction, etc. of the fluid when measuring. Furthermore, there is a low pressure drop which making the meter measurement results more accurate.

High Temperature Resistance up to 240℃

The High-temperature Flow Sensor launched by ADW are available in 2 types of material which are ceramic and stainless-steel cover. The High-temperature Flow Sensor with ceramic cover can withstand high temperatures up to 240°C, and stainless steel can withstand high temperatures up to 120°C. These ceramic and stainless-steel cover sensors will not affect the measurement accuracy of the product when used in continuously boiling hot water and ensuring that the ultrasonic heat meter outputs high-precision measurement results.

Tolerance up to 2.5MPa Pressure for Long Period

Compared to traditional plastic cover materials, the stainless steel, ceramic and other cover materials used in ADW High-temperature Flow Sensors have stronger rigidity. The product can withstand 2.5MPa pressure for a long time, and its pressure resistance is much higher than current products on the market with a pressure resistance of 1MPa sensor.

More Advantages

Low Voltage Drive, Good Consistency

The driving voltage of ADW High-temperature Flow Sensor is 5Vp-p. The product has low driving voltage and has passed the testing requirements of many European and American countries with good consistency result.

Good Weather Resistance

The product has been tested and verified that it is resistant to moisture, resistant to hot and cold, vibration, etc. It has good overall weather resistance, which can meet the requirements of high-temperature water measurement in industrial equipment and has high reliability.

Widely Adaptable

The sensor’s diameter of the high-temperature flow sensor is 16.8mm, and its size matches conventional ultrasonic heat meters, ultrasonic water meters, etc., and can be widely used in water meters. The product size is small and can be installed inside industrial equipment pipelines to provide high-precision technical support for water measurement in industrial equipment.
