Flange:DN50 to DN1600 / max. PN40
Overview
The 2-path ultrasonic flowmeter ABDT-UEM140 comes as battery or mainspowered and is designed to measure water flow in district heating plants,local networks,boiler stations,substations,chiller plants (including glycol mixes without type approval) and other general water applications.The ultrasonic signal is sent directly between the transducers. The advantage gained by sending signals from point to point is an extremely good signal strength.Features
