WIN Ultrasonic Flow Meters are designed to accurately measure the flow of water and water/glycol solutions in pipe sizes from 1/2" – 2 1/2" in diameter. The no-moving-parts design operates over 7 flow ranges (0.06 to 250 GPM) with excellent low flow performance (up to 100:1 turndown ratio). The WIN meter offers an IP65 enclosure with configurable 4-20 mA, with optional 0-5 V or 0-10 V analog output. This CE approved flow meter handles fluids 32°F to 250°F with maximum pressures up to 400 psi. Units are available an optional detachable LCD display with IP65 enclosure, pushbutton keypad, and Modbus RS485 serial interface.
