This RS PRO compact oval gear flow meter measures viscous fluids such as oils and fuels, providing low pressure loss and excellent chemical resistance. Its rugged construction assures reliable operation and a long service life.

The meter fits on a quarter-inch British Standard Pipe (BSP) thread and its standard flow ranges from 0.03 L/min to 4 L/min on 30 cSt oil and 0.15 L/min to 4 L/min on water-like substances. It contains a pair of oval gears that are pushed around by the fluid. Magnets transmit their rotations via a Hall-effect sensor, giving around 1,100 pulses per litre passed.

Built with corrosion-resistant stainless steel and a robust Viton O-ring, the meter is IP67-rated as watertight when submerged for 30 minutes in up to a metre of water.

This type of flow meter is used for measuring fuel usage in engines, as well as in hydraulics and the food industry.
