The JVM Series flow meters are economical and reliable positive displacement flow meters suitable for a wide variety of offset inks. The principal of operation is that of a gear pump, but in reverse; instead of the gears driving the medium, the medium drives the gears.

A non-intrusive sensor detects the movement of the gears and produces a square wave pulse for each gear tooth. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow.

The body and gears are manufactured from stainless steel with tungsten carbide shafts and tungsten carbide bearings. Sensors available include frequency output, analog output, fiber optic and intrinsically safe models.
