ACE 2024 | ADW lead-free piezoelectric ceramic sensors are launched simultaneously in North America and are widely welcomed by the international metering industry

On June 11, ACE 2024 (AWWA'S 2024 ANNUAL CONFERENCE & EXPO) was held in Anaheim, California, USA. During the exhibition, ADW specially exhibited its new product, lead-free piezoelectric ceramic sensors, and combined with the theme of "intelligent sensing empowers smart water services", it brought a series of ultrasonic flow measurement products to the scene, including water flow sensors that meet the drinking water standards of many countries, high-temperature flow sensors with a temperature resistance of up to 240°C, and water meter flow pipe sections with multiple models available, which are widely welcomed by international meter companies.

Ultrasonic flow transducer US0078: a new benchmark for smart water meter sensors

At the exhibition, professional visitors were particularly interested in the excellent ADW water flow sensor US0078. The resonant frequency of US0078 is 2110±30KHz, and the operating temperature is up to 90℃, which meets the needs of wide range ratio water meters. The product has set a new benchmark in the field of smart water meter sensors with its fast response, high sensitivity, stable electrical performance, high voltage resistance and compact size. Its application not only improves the performance of smart water meters, but also provides strong hardware support for smart water meter applications in the fields of homes, buildings and urban construction.

Fast response, high sensitivity

US0078 can quickly reach the peak in only 8 waves. Compared with products on the market that require 12 waves, it has a shorter response time and higher sensitivity.

Obvious echo difference, easy to use

The peak difference of the received echo is obvious, which facilitates the recognition and processing of signals, simplifies the measurement algorithm of the water meter, and helps to reduce production costs and improve efficiency.

Stable electrical performance

Within the temperature range of 10°C to 60°C, US0078 shows an extremely low zero flow drift value, with a change ratio of only 14.64%, which is much lower than similar competing products, ensuring stability under extreme temperatures.

High pressure resistance

After a static water pressure test of 4.8MPa, US0078 showed good stability and reliability. The product can withstand 2.5MPa water pressure for a long time and meet the water demand in a high water pressure environment.

Small size and well made

The US0078 has precise dimensions, an installation diameter of 10mm, and an accuracy error within ±0.2mm, which helps reduce errors during installation.

The material meets the drinking water standards of many countries

The product materials comply with international drinking water standards such as WRAS, ACS, KTW, etc., ensuring safety and hygiene in use 

High temperature flow sensor: a symbol of high temperature resistance

ADW's high temperature flow sensor is designed for liquid media, made of high pressure resistant stainless steel or ceramic material, with tight sealing performance, and can be used in direct contact with liquid. This design effectively avoids problems caused by unstable pressure and heat resistance, ensures the stability of sensor performance, reduces the interference of environmental factors on signal transmission, and thus improves the response speed and sensitivity of the sensor.

Optional shell material, high temperature resistance up to 240℃

High temperature flow sensors have two types of shells: ceramic and stainless steel. The high temperature flow sensors with ceramic shells can withstand temperatures up to 240°C, while stainless steel can withstand temperatures up to 120°C.

Long-term tolerance of 2.5MPa pressure

Compared with traditional plastic shell materials, the stainless steel, ceramic and other shell materials used in Audiway 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 similar sensors.

Low voltage drive, good consistency

ADW high temperature flow sensor is 5Vp-p. The product has low driving voltage and meets the testing requirements of many European and American countries with good consistency.

Good weather resistance and stable performance

After testing and verification, the product is resistant to moisture, heat shock, vibration, etc., has good overall weather resistance, can meet the requirements of high-temperature water metering in industrial equipment, and has high reliability.

Standard size, widely adaptable

The probe diameter of the high-temperature flow sensor is 16.8mm, which matches the size of conventional ultrasonic heat meters, ultrasonic water meters, etc., and can be widely used in water metering instruments; the product is small in size and can be installed inside the pipelines of industrial equipment.

Water meter flow pipe section: suitable for water meters with different pipe diameters

ADW's water meter flow pipe section is specially designed for ultrasonic water meters. It is made of plastic and measures the water flow velocity through a built-in ultrasonic sensor to accurately obtain flow data, providing a solid data foundation for water meter measurement.

No moving parts, high measurement accuracy

Thanks to the characteristics of ultrasonic measurement technology, there are no moving parts inside the base meter, which effectively avoids the generation of eddy currents and ensures high measurement accuracy.

Made of new environmentally friendly materials

The shell of this ultrasonic flow tube segment is made of new environmentally friendly materials, and its internal sensor strictly complies with the drinking water standards of many countries, ensuring the safety and hygiene of water quality.

Multiple models available

ADW water meter flow pipe sections are available in a variety of models, including DN10, DN15, DN20, DN25, etc., to match water meters with different pipe diameters.

To further promote the application of smart water management technology, ADW actively explores the research and development of intelligent hardware, and has successfully developed ultrasonic flow measurement products with integrated sensing, data conversion, cloud data upload and download, remote control and other functions.

With the arrival of the rapid development of the global smart instrument industry , ADW will give full play to its technological advantages in the field of ultrasonic flow measurement technology, develop and produce more high-tech sensor products and application solutions, and contribute technical strength to the development of the global meter industry!
