Kobold DPL Rotating Vane Flowmeter – Low Volume
The KOBOLD DPL is ideal for applications requiring a low cost, accurate means of measuring liquids. With all wetted parts constructed of synthetic materials. it resists aggressive media.
It is suited for a variety of industrial, commercial and laboratory applications.
The principle of operation is as follows:
A jet of liquid is directed at a free running turbine in a specially shaped chamber. The blade interrupts an internal infra-red beam and converts this into a pulse output with a frequency that is direction-ally proportional to the rate of flow. Sapphire bearings ensure high linearity and durability.
Its compact design allows it to be used in equipment where space is at a premium. The large number of pulse evaluation options available means that the system is suited to a wide range of applications:
