The Kobold DRZ series rotary piston positive displacement flow meter combines economy with high performance. The DRZ series is designed to measure any clean liquid with lubricating properties and viscosity ranging from 5 to 100 centistoke.

The unique design uses a single piston rotating on a camshaft to meter very precise volume of liquid with each rotation of the piston. Piston rotation is detected by a Hall effect sensor. The signal is processed by electronics into a blind pulse output (PNP or NPN based on model ordered) or a full featured controller with flowrate indication, analog output and switches.

An economical brass body is rugged and provides a pressure rating to 580 PSIG. The DRZ has a low pressure drop of 20 PSI maximum.

Use the DRZ with lubricating media such as:

  • Lubricating oil
  • Diesel fuel
  • Glycol mixtures
  • Waxes/pastes
  • Paint
  • Latex polymers
  • Sugar solutions
  • Detergents
