The Honeywell VersaFlow Sonic 1000 is an ultrasonic clamp-on flowmeter that can be mounted on the outside of a pipe to measure the flowrate of liquids. Installation takes only minutes and requires no special tools, thanks to our patented clamping devices. Additionally, the converter is pre-installed on the rail at the factory, further reducing installation time. The VersaFlow 1000 clamp-on design, with its robust industrial construction, provides a revolutionary solution for measuring flow.
