Product Description

The Sensotec FS012-18 is a high-performance, non-intrusive clamp-on ultrasonic flow switch designed for flow/no-flow detection of liquids in industrial applications. Its clamp-on design allows for easy installation without interrupting the process flow or cutting the pipe, significantly reducing installation time and cost compared to inline flow switches.

The FS012-18 operates on the proven transit time ultrasonic measurement principle, which provides accurate and reliable flow detection for a wide range of clean liquids. It supports bidirectional flow measurement with a velocity range of 0.02 m/s to 12 m/s, and is compatible with pipes ranging from 20 mm to 3000 mm in diameter.

The flow switch is fully field programmable via the built-in 2×20 character backlit LCD display and keypad, allowing users to easily adjust set points, hysteresis, and other parameters without the need for a computer. It provides multiple output options including SPST relay, OCT, 4-20mA analog, and frequency output, making it compatible with most industrial control systems.

Typical applications include cooling water monitoring, pump protection, leak detection, and process flow verification in manufacturing, chemical, food and beverage, and water treatment industries.
