DRB Series Paddle-Wheel Flow Meter
Brand: KOBOLD Instruments, IncThe KOBOLD DRB paddle-wheel flow meter can measure the flow of liquids in pipes up to 3 inches in diameter with pressures up to 250 PSIG.
It uses a PVDF paddle that’s designed to slightly protrude into the flow stream, enabling the flow meter to measure fluids with some small solids content, as well as dirty liquids, with a much lower risk of failure.
The paddle, supported on a sapphire bearing system, is durable, has an extended life span and provides excellent chemical resistance. The DRB is available with stainless steel or brass threaded bodies.
A Hall-effect sensor detects the passing of permanent magnets embedded in the paddle-wheel blades.
The sensor’s output is then transformed to a linear pulse frequency output or 4-20 mA signal.
Optional displays and controllers are available to provide analog outputs, local flow rate indication, and programmable setpoint switches.
