Loading Meter also available with DN 80 (3“) size, 90 m³/h Oval Wheel Meter OV 800 • only two moving parts • excellent metrological characteristics • no inlet or outlet section required • robust design • wear-resistant proximity switches with NAMUR power supply acc. to DIN EN 60947-5-6 for simple and reliable signal processing • optional with installed Pt 100 for electronic temperature compensation Loading meter type OV 800 (1) in a loading skid for lubricating oil with strainer (2) and centrifugal gas separator (3) Measuring principle Oval wheel meters are positive displacement flow meters. The measuring element consists of two precision oval wheels, driven by the fluid. Each revolution of the oval wheels displaces a precisely known volume of liquid through the meter. The number of revolutions therefore is directly proportional to the measured volume. Technical Data accuracy liquid temperature ± 0,3% to ± 0,1% (depending from flow range and liquid) -10°C bis +60 °C nominal size nominal pressure process connection overall length NAMUR pulses (4 pulses per liter) safety class NAMUR DIN EN 60947-5-6 ATEX 100; Pressure Equipment Directive Approvals for custody transfer available (Z 5.241 / 01.55) Measuring range Measuring range Viscosity ranges 40 to 1500 l/min viscosity related 0,3 to 17 mPas ; 3,5 to 120 mPas
