KOBOLD OVZ flowmeters offer users the advantages of positive displacement technology at a rotameter price. Suitable for viscous media ranging from hydraulic oils to light gear oils, the OVZ eliminates problems associated with viscosity changes during operation. The OVZ’s cost conscious design allows for easy maintenance. Since the only wear components are the gears and their axles, the two step rebuild process can be performed in a few minutes with no recalibration required. The OVZ is available with either Hall-effect, or inductive sensors, giving the user a selection of output signals. Available are NPN, PNP or Namur configurations ideal for connecting to a wide variety of controller devices, including KOBOLD’s full line of frequency input devices. Typical applications for the OVZ include central lubrication systems for paper machines, filling transmission fluid into gearboxes, and hydraulic systems.
