Kobold DON-110HR11R0M0 Product Overview
The Kobold DON-110HR11R0M0 is a high-precision positive displacement oval gear flow meter engineered specifically for tracking and monitoring clean, lubricating industrial fluids like hydraulic oils, diesel fuel, and lubricants. Constructed with a rugged aluminum housing and lightweight PPS (Polyphenylene Sulfide) oval gears, this volumetric sensor delivers highly repeatable flow tracking across a wide operational viscosity spectrum without needing any upstream or downstream pipe straighteners.

Positive Displacement Measuring Principle
The DON-110HR11R0M0 utilizes two interlocking, precision-molded oval rotors that reside within a tightly calibrated measuring chamber. As fluid travels through the body, it forces the gears to rotate, transporting a known, constant volume of liquid per revolution. High-resolution permanent magnets embedded inside the gears trigger a robust external reed switch sensor block with every pass. This mechanical principle delivers a typical repeatability of $\pm0.03\%$ and an outstanding overall measurement accuracy ranging between $\pm0.5\%$ and $\pm1\%$ of the actual reading.
Durable, Low-Maintenance Field Integration
Thanks to the pairing of a lightweight aluminum chassis and low-friction PPS rotors, the DON-110HR11R0M0 features an exceptionally low pressure drop profile, preventing back-pressure issues even when dealing with higher-viscosity oils. This model is configured with a raw reed switch pulse output, rendering it highly efficient for direct wiring to remote digital batch counters, PLC pulse-input cards, and remote monitoring interfaces. The robust IP65-rated body and lack of a delicate local display face make it ideal for high-vibration engine rooms, mobile fueling skids, and space-constrained industrial lubrication systems.
