Kobold DRZ Rotary Piston Flowmeter
The KOBOLD DRZ Series rotary piston positive-displacement flowmeter combines economy with high performance. The DRZ Series flowmeter 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 KOBOLD DRZ Series positive-displacement flowmeter has a low pressure drop of 20 PSI maximum.
