With the rapid development of the IoT technology, the demand for high-performance ultrasonic sensors for ultrasonic smart water meters applied in smart buildings is becoming more and more obvious. In order to further improve the measurement performance of ultrasonic smart water meters, AUDIOWELL launches a new generation of water meter flow transducer - US0078 from the perception layer.
Compared with similar competitors on the market, this product has more stable electrical performance and stronger voltage resistance, high sensitivity, fast peak value, and easier signal processing, which helps to improve the measurement accuracy of ultrasonic water meters and provide a more competitive hardware foundation for the iterative upgrade of ultrasonic smart water meters.
AUDIOWELL water flow transducer high performance, mainly reflected in:
Fast peak value, high sensitivity, easy signal processing
AUDIOWELL water flow transducer only needs 8 waves to reach the peak to complete the vibration, compared with 12 waves to reach the peak of other products less than 4 echo signal time, shorter time, higher sensitivity.
From the waveform point of view, AUDIOWELL US0078 receive the echo of the difference between the various peaks is obvious, the difference between adjacent signal waves is greater than similar sensors, easy to identify the first, second, third, or more recycled signal waves, in the perception level to reduce the difficulty of signal processing, which is conducive to simplifying the algorithm of the measurement of the water meter, for the water meter research and development, manufacturing enterprises to reduce costs and increase efficiency to lay the core hardware foundation.
Electrical performance in high and low temperature zero flow drift value more stable
Comparison of zero-flow drift values between AUDIOWELL US0078 and similar sensors in low and high temperature environments. In the case of zero flow, AUDIOWELL US0078 in 10 ℃ low-temperature environment, receiving amplitude of 432mV; in 60 ℃ high-temperature environment, receiving amplitude of 369mV, amplitude change ratio of 14.64%, the other two similar competitors amplitude change ratio were 19.32% and 24.66%, amplitude change is significantly lower than similar products in the market, indicating that the electrical performance of its high and low temperatures under the Zero flow drift value is highly stable and higher than the industry level.
Maximum pressure resistance up to 4.8MPa, strong reliability
AUDIOWELL water flow transducer US0078 is subjected to static hydraulic test, the test condition is to keep the water pressure of 4.8Mpa for 15min, comparing the test parameters before and after the test, it is found that the performance of the product has always been stable, in line with the specification requirements. In addition, AUDIOWELL US0078 can work continuously under 2.5MPa environment for a long time, which meets the needs of buildings with long water consumption time, high water pressure in peak period and high pressure-bearing requirements.
Small size and compliance with national drinking water standards
AUDIOWELL water flow transducer US0078 performance products resonant frequency of 2110 ± 30KHz, can realize the requirements of the wide ratio of water meters; large operating temperature range, temperature resistance up to 90 ℃, effectively resist high and low temperature environment, applicable to different latitudes. Meanwhile, the materials used in the production of the products have passed the drinking water standards of various countries, such as WRAS, ACS, KTW, etc., which are safe and hygienic. In addition, the products must be tested one by one before leaving the factory to ensure that each performance parameter is within the specified range and has good consistency.
Therefore, the products can be used in pairs without pairing test before assembly, which effectively simplifies the assembly process of smart water meters and improves the operational efficiency of water meter manufacturers.
Overall, AUDIOWELL water flow transducer US0078 has high sensitivity, reaches peak value quickly, and the electrical properties are highly stable with zero flow drift value at high and low temperatures, with good consistency. The product is small in size, high accuracy of the appearance of the dimensions, reducing installation errors, and has the characteristics of high and low temperature resistance, high humidity resistance, high pressure resistance, etc., to meet the requirements of a wide range than the water meter, the product batch consistency is good, safe and hygienic, and has been widely used in the home, buildings, urban construction and other areas of intelligent water meters.
