4-20mA RS485 Clamp-On Ultrasonic Flow Meter Transducer | External Snap-On Card Flow Sensor

Product Description:
The 4-20mA RS485 External Card Flow Watch Snap Clamp-On Ultrasonic Flow Meter Transducer is engineered with a uniquely innovative structural design. Featuring a circular magnetic steel mechanism, it allows for quick and secure snap-on installation—completing setup and flow measurement in just 2–3 minutes.

Equipped with a high-contrast OLED display, the unit ensures excellent visibility even in low-light environments. Designed for real-time flow monitoring and control, our model  is ideal for industrial production processes, helping improve product yield, reduce manpower requirements, and enhance operational efficiency.

This ultrasonic flow meter supports a wide range of pipe materials, including stainless steel, carbon steel, copper, and various plastics (PVC, PVDF, PPR, PPH, HDPE). It is also compatible with clean liquid media, such as acids, alcohols, chemical solvents, beverages, purified water, and even soft drinks like Coca-Cola water.
