Screw-Type Volumetric Flow Meter for Viscous Media Model OM... Description The KOBOLD screw-type volumetric flow meter based on the principle of positive displacement was developed in response to the need to measure and control viscous media. It was specially designed to measure viscous media with nonabrasive properties. Variations in viscosity in the range to 000 mm /s have no effect on measurement results within the measuring accuracy. The KOBOLD screw-type volumetric flow meter satisfies the stringent demands for greater accuracy, reliability and economic efficiency. Two spindles with cycloidal profiles form the basis of the screw-type volumetric flow meter. Spindles manufactured with extreme precision are supported at each end with a ball bearing. The axially forced measuring medium causes the spindles to rotate uniformly. The rotary motion is picked off with inductive proximity sensors or Hall-effect sensors and converted to a frequency signal. An exact measurement of the delivered flow volume is obtained with the volumetrically defined measuring chambers. Combined with downstream evaluation electronics, the KOBOLD screw-type volumetric flow meter becomes a flexible measurement and control system for viscous media. Benefits Greater viscosity range (... x 0 6 mm /s) Greater measuring accuracy (max. 0.% of span) Greater measuring span: (:00 with 0.% accuracy) (:0 with 0.% accuracy) Almost completely insensitive to viscosity Greater flow rate combined with minimum space requirements High degree of operational reliability and long service life Pulsation-free principle of measurement Self-cleaning measuring chambers Choice of installation position Areas of Application Furnaces EL heating oil, S heating oil, diesel oil Hydraulics, test stands Hydraulic oil, lubricating oil, gear oil Mixing and dosing systems Polyhydroxy alcohol, isocyanate Additives for gasoline, cement...

Pulse Generator for Screw-Type Volumetric Flow Meters Model OM... Method of Operation The rotor of the screw-type volumetric flow meter rotates at a precisely defined distance in front of the pulse generator. The pulse generator generates a pulse for every pole that moves past it. The screw-type volumetric flow meter is checked and delivered with a built-in dry sleeve. The transmitter insert for the pulse generator can be replaced online in a full line, without having to re-adjust the clearance to the rotor.
