OME Screw Spindle FlowmeterBrand: KOBOLD Instruments, Inc.
The Kobold screw-type volumetric flowmeter has proven itself in many applications over a long period of time; it has now been extended with an economical alternative - the OME type series - for the economical measurement or batching of viscous media.
These measuring sensors have been designed for viscous, non-abrasive media of 1 - 5000 mm2/s; they have been introduced as a response to today's innovative metrology and its demands for greater accuracy and reliability.
The screw-type volumetric meter works with the principle of positive displacement. Two cycloidal spindles, whose rotation is sensed by one or two sensors, are at the heart of the flowmeter.
A new technique has been patented to sense the spindles directly, thus providing a compact and economical volumetric meter. The axial flow of the forced measured medium causes the pair of spindles to rotate in a uniform, non-pulsating manner.
The spindles have been manufactured with extreme precision. They are supported at their ends by ball bearings. The pair of spindles form volumetrically defined measuring chambers, which are a measure of the delivered volumetric flow.
These unit volumes are evaluated by downstream electronics.
A double pulse generator can be used for direction sensing and doubling the pulses of pulse generator.
