KOBOLD’s new OME positive displacement flowmeter breaks through the price barrier for meters incorporating helical-gear technology. The OME provides the quiet, non-pulsating, low pressure-loss operation for which helical gears are renowned, at a price comparable to oval-gear technology. The OME is designed to be used with non-abrasive, lubricating liquids whose viscosity lies in the range of 1–5000 cSt. The precision and reliability of the device is equivalent to our top-of-the-line OME helical-gear meters. . . no performance sacrifices have been made. In a design diverging from conventional systems, the rotation of the OME’s helical gears is detected by externally mounted proximity switches. This not only reduces the unit’s price, but also makes a second sensor possible for little additional cost. This second (optional) sensor may be used for detection of flow direction or frequency multiplication. The standard sensor is amplified by a PNP collector circuit. An optional NAMUR output is available.
