Nutating Disc meter is ideal for end of hose use, in line or mounted to one of our Rotary Vane or 400B Series Diaphragm Pumps. It is able to store and display the current flow amount (total) or the cumulative flow amount (totalizer) in any of six user-specified units. The 850 has a mass air sensor that distinguishes between fluid and air. That means the 850 stops metering when you've finished emptying a container, adding an extra degree of accuracy.

The rugged corrosion-resistant body for the most demanding applications is easy to install with consistent accuracy up to +/- 0.2%. Battery powered, LCD display.
