Flow meters are used for measuring dispensed liquids such as fuel, diesel and water in a precise, reliable, robust way.
Mechanical Flow Meters
This is the most commonly used measurement system for measuring water and oil. The fluid, most commonly water, enters in one side of the meter and strikes the nutating disk, which is eccentrically mounted. The disk must then “wobble” or nutate about the vertical axis, since the bottom and the top of the disk remain in contact with the mounting chamber. A partition separates the inlet and outlet chambers. As the disk nutates, it gives direct indication of the volume of the liquid that has passed through the meter as volumetric flow is indicated by a gearing and register arrangement, which is connected to the disk. It is reliable for flow measurements within 1 percent.
The Horn Tecalemit Meter Z 400 is a mechanical meter with nutating disc. The nutating discs are moved by the delivered medium and transmit the turning motion – in proportion to the liquid flow via a gear mechanism to the visual indicator mechanism.
