WM-3000 Line-Powered Ultrasonic Water Meter with Pulse Output Overview

The H2O Degree WM-3000 line-powered ultrasonic water meter is a ultrasonic flow sensor that clamps on to the outside of a pipe and can monitor the flow of liquid through metal or resin pipes ranging from 1/4″ to 2″.

No pipe modification is needed with the WM-3000 water meter. The unit can be mounted to a machine, while running, with a Phillips screwdriver. By mounting to the outside of the pipe, both cost and time are kept at a minimum.  The ease of installation, and associated cost savings with mounting externally, open up countless machines to flow monitoring that were once unrealistic.

The WM-3000 can detect virtually any type of liquid. This includes the flow of water (including deionized), oils, chemicals, consumer products, etc. Limitations of traditional liquid flow sensors do not apply to the WM-3000 because the unit does not directly touch the liquid.
