Kobold DON-105GN11H0M0 – DON Oval Gear Flow Meter, Aluminium, 1/8″ NPT, Hall Pulse Output
The Kobold DON-105GN11H0M0 is a positive displacement oval gear flow meter from Kobold’s DON series, in the smallest DON-105 size. It has an aluminium body with PPS rotors, a 1/8″ NPT connection and a measuring range of 0.5–36 l/h (0.13–9.5 GPH). It is fitted with a Hall-effect sensor with push-pull pulse output.
In an oval gear meter, two oval rotors turn with the flowing liquid and trap a fixed volume with every rotation. Counting the rotations gives a direct volume measurement that is independent of the liquid’s conductivity, so the DON is ideal for oils, fuels and other non-conductive liquids that magnetic flow meters cannot measure. The meter handles low and high viscosities and offers high accuracy, with ±0.03 % typical repeatability. The aluminium version is suited to fuels, fuel oils, lubricating oils and hydraulic oils. The Hall-effect sensor gives an active push-pull pulse signal that connects directly to a PLC, counter or batch controller without a pull-up resistor.
