Overview

Ultrasonic flowmeter D118 is a high-performance general purpose clamp-on flow meter incorporating the latest developments in universal transit-time digital signal processing to offer excellent accuracy and repeatability for a wide variety of liquids. The flow meter measures the time it takes an ultrasonic signal to travel a known distance with the flow stream and another signal travelling against the flow stream, determining the velocity of the fluid being measured.
Ultrasonic flowmeter D118 clamp-on meter can also be ordered with insertion transducers to eliminate problems with pipe wall thickness, liners, wall deposits, and where difficult piping configurations present signal strength issues.
