The DON positive-displacement flowmeter is suitable for measuring clean, high and low viscosity liquids such as lubricating/hydraulic oils, diesel fuels, chemicals, solvents, resins and pastes. It employs two precision-machined oval gears that allow for a very specific volume of liquid to pass through the meter with each rotation. Reportedly, these gears enable the flowmeter to precisely measure liquid flow over a very wide viscosity range. Flow Ranges span from 0.13 to 9.5 GPH to 40 to 660 GPM. Line sizes rune from 1/8" to 4" and fittings are NPT or BSP threaded, ANSI, or DIN flange. Maximum temperature ranges up to 250°F.
