Union connection electromagnetic flow meter
The electromagnetic flow meter with union connection is designed for applications that require easy installation, quick maintenance, and reliable flow measurement. By adopting a union-type coupling structure, the meter ensures a secure and leak-free connection while allowing the sensor to be removed without dismantling the entire pipeline. This makes it ideal for systems where frequent inspection or cleaning is needed.

Featuring high measurement accuracy and excellent stability, the union-connected electromagnetic flow meter is suitable for conductive liquids such as water, wastewater, chemical solutions, food-grade mediums, and slurry with low solids. The device is equipped with advanced signal processing technology, offering a wide turndown ratio, strong anti-interference capability, and long-term operational reliability.

Its compact design, corrosion-resistant liners, and multiple electrode materials make it adaptable to various industries including water treatment, HVAC, chemical dosing, agriculture irrigation, and industrial process control. The union connection design reduces installation time and cost, making it an efficient solution for modern fluid management systems.

Open channel ultrasonic flowmeter
The Ultrasonic Open Channel Flow Meter is a highly reliable and non-contact instrument designed for accurate flow measurement in open channels, canals, and water treatment systems. Using advanced ultrasonic technology, the device continuously measures the liquid level above a primary structure—such as a weir or flume—and converts it into flow rate through a built-in hydraulic formula.
