All-Plastic Low Flow Paddle-Wheel Sensor - DPL

If you are looking for accuracy and economy in a compact package, consider the KOBOLD DPL. It has a proven history, with tens of thousands being implemented into various applications every year.

HOW IT WORKS

The DPL is built on the well-known principle of the paddle-wheel, also known as a rotating vane. A concentrated jet of media is directed at a freely rotatable turbine wheel in a specially shaped chamber. The blade interrupts an infra-red optical beam and converts this into a pulse output with a frequency that is proportional to the rate of flow.

BUILT WITH EXCELLENCE

Built by hand in Pittsburgh, the DPL offers quality and excellence to users around the world. It is engineered for transparent, water-based, low viscosity media. It resists aggressive media, with all wetted parts constructed of polypropylene, polysulfone, NBR, FKM, or EPDM. It also features sapphire bearings that ensure high linearity and durability. A compact design offers compatibility with applications that offer limited installation space. It is available with a frequency output, an analog output, a compact electronics package, or a pointer indicator with an analog output.

THE TECHNICAL DETAILS

The DPL offers an accuracy of ±2.5% of the full scale for standard versions and ±5% for OEM versions. The linearity is ±1% and it offers a protection rating of IP65. The media temperature range is -40 to 158 °F. The maximum pressure is 145 PSIG.

OEM POTENTIAL

With its low cost, the DPL is an ideal candidate for OEM applications. Please contact your KOBOLD representative to discuss your specific application and the suitability of the DPL for your needs.
