Gear Flow Meter

The DOPAG gear flow meter (GFM) has been developed specifically for use in DOPAG metering and mixing systems. In processes involving one-part media such as adhesives, sealants, greases and oils, it is used for measuring the exact material flow rate at any given moment. The measuring principle is based on the volumetric gear displacement system, characteristic for its accuracy and compressive strength. The measuring element comprises of a very precisely fitted pair of gears placed in the housing of the flow meter. The rotation of the measuring element is detected by a contactless sensor system and converted into digital signals. The signals can also be multiplicated via adjustable amplifier electronics in order to achieve a finer measurement resolution. This allows the smallest flow rates to be detected. With its robust and reliable design a high process stability is guaranteed any time. Depending on the flow rate, pressure level and properties of the material to be measured, different types are available.
