Accurate to 1%, this turbine meter sets the standard for accuracy, ease of use and safety. It has factory presets for 20 fluids and UL/ATEX listing on the entire meter, not just the electronics as competing brands have. Replaceable (2) AA batteries keep your meter running and downtime to a minimum. A rubber boot helps protect the meter and electronics from impact damage. For a robust meter you can depend on, choose Fill-Rite, the most trusted name in pumps and meters.
