DRZ - Rotary Piston Flow Meter

Brand: KOBOLD Instruments, Inc

The KOBOLD DRZ rotary piston positive-displacement flow meter combines economy with high performance. 

This metal flow meter is designed to measure any clean liquid with lubricating properties and a viscosity ranging from 5 to 100 centistokes. 

The unique design uses a single piston rotating on a camshaft to meter a very precise volume of liquid with each rotation of the piston. 

Piston rotation is detected by a Hall Effect sensor, and the signal is processed by electronics into a blind pulse output (PNP or NPN based on model ordered) or a full-featured controller with flow rate indication, analog output and switches. 

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