ADW Vortex Flow Sensor to debut at ASIA WATER 2026

2026.04.05

Based on the Kármán Vortex Street Effect: Precisely Addressing Challenges in Large Flow, High Viscosity, and Complex Water Quality Measurement

From April 7th to 9th, 2026, ASIA WATER 2026, Asia's premier water treatment industry event, will be held at the Kuala Lumpur Convention Centre in Malaysia. ADW will showcase its independently developed Vortex Flow Sensor, focusing on the water and industrial fluid treatment sectors. This product is specifically designed for liquid and gas flow measurement, exhibiting exceptional performance under complex conditions such as high flow rates, high velocities, and high-viscosity coolants. It provides a cost-effective flow monitoring solution for water treatment, industrial circulating cooling, and water supply networks.

Scientific Principle: Karman Vortex Street Effect
The core measurement principle of the ADW Vortex Flow Sensor is based on the classic Karman vortex street effect. When a fluid (liquid or gas) flows through a non-streamlined vortex generator within the sensor's pipe, regular vortices are generated alternately on both sides of the generator, forming a vortex street. Within a certain Reynolds number range, the shedding frequency of the vortex street is directly proportional to the fluid velocity. The sensor accurately captures this frequency signal through a high-sensitivity piezoelectric or capacitive sensing element. Combined with a built-in fluid dynamics model and adaptive digital signal processing algorithm, it ultimately outputs a pulse or analog signal corresponding to the volumetric flow rate, achieving stable and real-time flow measurement.

This principle has the theoretical advantage of not depending on fluid density, temperature, pressure and other physical properties (it is only related to flow rate and the characteristic size of the generator), and has no moving parts, thus fundamentally avoiding the risk of mechanical wear and jamming.


Core Product Advantages


Excellent resistance to bubble and impurity interference
The vortex signal strength is mainly affected by the flow velocity and the geometry of the vortex generator, and is not sensitive to tiny bubbles or suspended particles entrained in the fluid. Combined with ADW's proprietary signal filtering and adaptive gain control technology, it can effectively suppress signal noise in gas-liquid two-phase flow and wastewater environments, ensuring low drift and high repeatability measurement results.


Modular structure, extremely low pressure loss
The product adopts a compact modular design, with the vortex generator and detection unit able to be independently disassembled and assembled, facilitating on-site maintenance and range changes. The flow channel structure has been optimized for fluid dynamics, resulting in pressure loss far lower than that of orifice plates or turbine flow meters of the same diameter, making it particularly suitable for energy-sensitive gravity flow or low residual pressure pipeline systems.


Instantaneous flow accuracy reaches ±3% F.S. 
Throughout its full range, the ADW Vortex Flow Sensor achieves an instantaneous flow measurement accuracy of ±3% of full scale (F.S), meeting the routine metering requirements of industrial process control and water treatment. For large flow ranges, the sensor exhibits excellent repeatability, facilitating accurate monitoring of water or coolant consumption.


Optional temperature sensor enables simultaneous flow and temperature detection. 
For high-viscosity coolant or hot water circulation systems, ADW offers an option with a built-in temperature sensor. Users can simultaneously acquire fluid temperature and instantaneous flow data, facilitating the calculation of heat exchange or cooling efficiency without the need for additional temperature measurement points, thus reducing system integration costs.


It has a wide range of applications and directly addresses industry pain points.
At the Asia Water Treatment Exhibition, the ADW technical team will focus on demonstrating the application of this sensor in the following typical scenarios:


Industrial circulating cooling water systems: 
In high-flow-rate, high-viscosity coolants (such as ethylene glycol solutions), traditional electromagnetic or ultrasonic sensors may experience signal attenuation or scaling, while vortex sensors, with their anti-impurity characteristics and low pressure loss advantages, can operate stably for a long time.


Wastewater treatment plant inlet and outlet water and aeration pipelines: 
In environments with drastic changes in bubble content, vortex sensors can still maintain reliable frequency counting, assisting in process optimization.


High-flow-rate raw water and water transmission pipelines: 
High flow rates can be directly measured without diameter reduction, reducing project costs.


Exhibition Information and On-site Exchange
ASIA WATER 2026 is the most influential technical exchange and business cooperation platform in the Southeast Asian water treatment industry. ADW cordially invites water companies, EPC contractors, equipment manufacturers, and industry experts to visit the ADW booth at the Kuala Lumpur Convention Centre from April 7-9, 2026 (booth number will be announced later). Observe the dynamic demonstration of the Vortex Flow Sensor, obtain technical materials, and engage in in-depth discussions with R&D engineers regarding customized interfaces, range selection, and communication protocol adaptation.
