Product Description

The KOBOLD DRH Series paddle-wheel flow sensor offers a variety of seven material combinations, enabling it to withstand a very wide range of water-like, low-viscosity liquids or aggressive chemical solutions. The DRH is a compact liquid flow sensor that employs permanent magnets embedded in a rotating paddle wheel. A Hall-effect sensor detects the magnet passing and provides an output proportional to flow rate. The DRH paddle-wheel flow sensor can be supplied with a frequency output, 4-20 mA output or a versatile compact electronics package providing an LED display, 4-20mA output or programmable setpoint switches. The compact size, variety of material combinations and economical price make the KOBOLD DRH the perfect paddle-wheel liquid flow sensor for industrial or OEM applications with maximum pressures up to 580 PSIG.
