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.
