Loading Meter available with DN 100 (4“) size, 200 m³/h Oval Wheel Meter OV 1000 • 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 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. Loading meter type OV 1000 (1) in a truck loading farm with additive dosing (2), strainer (3) and centrifugal gas separator (4) Technical Data accuracy liquid temperature ± 0,3% to ± 0,1% (depending from flow range and liquid) -10°C to +60 °C nominal size nominal pressure process connection overall length NAMUR pulses (2 pulses per liter) safety class EG declaration of conformity, approvals, standards NAMUR DIN EN 60947-5-6 ATEX 100, Pressure Equipment Directive Approvals for custody transfer available (Z 5.241 / 03.57) Measuring range Measuring range Viscosity ranges 85 to 3300 l/min viscosity related 0,3 to 17 mPas ; 3,5 to 120 mPas
