INPUT 4.1 MEASURED VALUE Volume and volumetric flow The field of application of all Oval Wheel Meters of the OaP series comprises measuring, dosage, and controlling of liquids. Oval Wheel Meters of the OI series meet all of these requirements. They are used for the measurement of intermediate and final liquid products such as liquified gases, acids, alkaline solutions, fats, alcohol, solvents, dispersions, polymers, polycondensates, paints, colors, adhesives and other media. Please note the Oval Wheel Meter's capability to measure liquids with very high viscosities with nearly no pressure loss. The high accuracy provided by the OaP series Oval Wheel Meters ensure a maximum quality of the products being manufactured. Oval Wheel Meters of the OaP series are manufactured with nominal widths of 25 to 400 mm. Depending on the nominal width they can be used for up to PN 100 with a maximum operating temperature of up to 290 °C. Oval Wheel Meters belong to the group of direct volumetric meters for liquids with movable partition walls (displacement flow meters). The Oval Wheel Meter consists of a measuring chamber housing with two pivoted oval wheels, which are toothed and roll off in counter-rotations around each other. Each revolution of the oval wheels displaces four discrete volumes of fluid (defined by the space between oval wheel and measuring chamber) through the counter. The number of the rotations is a mea- sure for the volume. For all these oval wheel meters a wide choice of accessories is available including mechanical, pneumatical, electrical and electronic trans-mitters. Their signals may be used for remote counting, flow measuring and flow control as well as for data processing systems. In addition, automatic batch control systems (with appropriate valves) of the most varied constructions and working principles are available to facilitate dosage of media.
