Features
  • Suitable for Clean, Lubricating Oils
  • Maintains Precision with Viscosity Change
  • Five Material Combinations Available
  • Economically Priced
  • Easy to Maintain
  • Optional Analog Output, Frequency Output or Digital Indicating Output Options

KOBOLD OVZ flowmeters offer 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, a 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, and a selection of output signals. NPN, PNP, or NAMUR configurations are ideal for connecting to a wide variety of controller devices, including KOBOLD’s full line of frequency input devices. The OVZ is also available with analog, frequency, or digital indication output options. Typical applications for the OVZ include central lubrication systems for paper machines, filling transmission fluid into gearboxes, and low pressure hydraulic systems.
