Product Name: Oval wheel meter series OI

Range of Application
The Oval wheel meters of the OI series are designed for measuring volumes and flow rates in various processes such as custody transfer, dosage, and liquid control. They are particularly suitable for liquids with high viscosities and ensure minimal pressure loss and high accuracy. The meters are available in nominal widths of 25 to 100 mm and can operate up to PN 40 with a maximum temperature of 180°C.

Measuring Principle and System Configuration
Measuring Principle: Utilizes two pivoted oval wheels that rotate counter to each other, displacing fluid volumes.
System Configuration: Includes accessories like mechanical, electrical, and electronic transmitters for remote metering and data processing, with options such as pulse pick-ups, indicators, and electronic counters.

Input
Measured Value: Volume and volumetric flow

RANGE OF APPLICATION The range of application of all Oval wheel meters of the OI series comprises measuring of volumes and flowrates in the process, custody transfer, 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 oval wheel meters series OI ensure a maximum quality of the products being manufactured. Oval wheel meters of the Ol series are manufactured with nominal widths of 25 to 100 mm. Depending on the nominal width they can be used for up to PN 40 with a maximum operating temperature of up to180 °C. 3. MEASURING PRINCIPLE AND SYSTEM CONFIGURATION 3.1 MEASURING PRINCIPLE 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 Measure for the volume. Pulse pick-up AG19 / AG20 see D-EN-17202-00 Rev.A (attached devices acc.

There is an extensive program for accessories available for the oval wheel meters. This includes mechanical, electrical and electronic instrument transmitters, whose signals can be used for remote metering, flow measurements and control and supply of data processing systems. In addition, we also offer quantity preselection devices for dosing with appropriate valves of the most varied construction and functions. see D-EN-1706-00-Rev.A see D-EN-1707-00-Rev.A The UST comes by default with a local display, a 4-20mA current output for the flowrate signal and HART-communication (driver acc. FDT available), as well as a pulse output acc. NAMUR for counting (original or scalable). The oval wheel meter series OI is also available with a heating jacket, type OUI. 4.
