Description Specifications Literature Description The KOBOLD DRH series paddle flow sensor offers seven material combinations, enabling it to stand up to virtually any liquid or aggressive chemical. Its compact design employs permanent magnets embedded in a rotating paddle wheel. A Hall effect sensor detects the magnet passing and provides an output which is proportional to flowrate. The DRH can be supplied with a frequency output, 4-20 mA output, or a versatile compact electronics package that provides an LED display, 4-20mA output, or programmable setpoint switches. The DRH is ideal for industrial or OEM applications.
