The KOBOLD series DRG has the winning combination of compact size, low cost and versatility which makes it the perfect product for OEM flow measuring applications. The DRG series is a paddle flow sensor which uses a Hall effect sensor to detect the passing of permanent magnets imbedded in the rotating paddle. The DRG can be supplied with a frequency output, 4-20 mA output or a versatile compact electronics package providing an LED display, 4-20 mA output or programmable setpoint switches. The DRG series is offered in five material combinations. An all plastic version is available which makes the DRG series suitable for use with high purity water and many types of aggressive chemicals. Housing is Polypropylene and the maximum pressure is 100 PSIG.
