There are inherently more leakage paths in this design and disv tends to be used where longer flow meter life is required rather than high performance; however, close clearances between the disc and chamber ensure minimum leakage for accurate and repeatable measure of each volume cycle.

How Sensor Picks up the reading — These flow meters may use a Hall sensor to sense the rotation and the same was converted into equivalent flow. Something to keep in mind, is that due to the nutating discs nature, the accuracy of this type of flow meter can be adversely affected by fluctuations in liquid viscosity. Call for Pricing Ask a question about this product Availability Usually ships in: The movements of the disc are transmitted mechanically to a transmitter.

Niagara Meter’s products include Nutating Disc, Oscillating Piston and Turbine technologies for use in industrial flow measurement applications. The position of the disc divides the chamber into compartments containing an exact volume. When fluid enters the chamber, it causes the metee to wobble nutatetransferring the displaced volume to the register.

Oils dish, mineral, vegetable, and fuel. The compartments are filled and emptied with each cycle. Liquid enters a precision-machined chamber containing a disc which nutates wobbles. Liquid pressure drives the disc to wobble and a roller cam causes the nutating disc to nutwting a complete cycle.

Nutating Disc Flow Meter Working Principle, Applications, Advantages and Disadvantages

A mechanical or electromagnetic sensor detects the rocking of the pin and the flow is measured. Nutating disc meters are one of the most common types of positive displacement flow meter.

The nutation causes a pin, mounted on the sphere perpendicular to the disc, to rock.

The position of the disc divides the chamber into compartments containing an exact volume. We’ll assume you’re ok with this, but you can opt-out if you wish. This motion is translated into rotary motion by means of a ball and shaft, which is attached to the disc.
