OVZ ECONOMICAL OVAL-GEAR FLOW METER - Kobold

Economical Oval-Gear Flow Meter Model OVZ2DescriptionKOBOLD OVZ flowmeters offer the advantages of positivedisplacement technology at a rotameter price. Suitable for viscousmedia ranging from hydraulic oils to light gear oils, the OVZ eliminatesproblems associated with viscosity changes during operation. TheOVZ’s cost conscious design allows for easy maintenance. Sincethe only wear components are the gears and their axles, a twostep rebuild process can be performed in a few minutes with norecalibration required. The OVZ is available with either Hall-effect orinductive sensors, and a selection of output signals. NPN, PNP, orNAMUR configurations are ideal for connecting to a wide variety ofcontroller devices, including KOBOLD’s full line of frequency inputdevices. The OVZ is also available with analog, frequency, or digitalindication output options. Typical applications for the OVZ includecentral lubrication systems for paper machines, filling transmissionfluid into gearboxes, and low pressure hydraulic systems.SpecificationsAccuracy: ±2.5% of f. s.Turn-Down: 10:1Viscosity Range:10...800 cStRequired Filtration:30 micron filterrecommendedTemp.
