Oval gear flow meters created for high pressures

Products DON-H flow meters high pressure Kobold oval gear positive displacement


DON-H high pressure oval gear positive displacement flow meters from Kobold are said to offer reliable flow rate measurement for demanding process conditions.

The flow meters  are suitable for clean, high, and low viscosity liquids such as lubricating/hydraulic oils, petroleum, grease, diesel fuels, chemicals, solvents, resins, and pastes.

Because of the mechanical nature of the measurement principle, media with particulate matter is not suitable for use with the units.

The flow meter uses two precision-machined oval gears which allow for a very specific volume of liquid to pass through the meter with each rotation, providing a true volumetric flow measurement.

The gears enable the DON-H to precisely measure liquid flow over a very wide viscosity range, accommodate fluctuating flow rates, a provide accuracy for applications with intermittent flow, the company says.
