LEVEL METER

Document Type and Number:

United States Patent Application 20080210003

A level meter for measuring the fill level of a medium in a vessel, includes a reference container that can be connected to the vessel in a manner whereby the level in the reference container is identical to that in the vessel. The reference container is provided with an adapter unit for a microwave level meter operating by the radar principle which adapter unit encompasses an injection device for coupling-in a microwave signal. This constitutes a low-cost solution for connecting a microwave level meter to a reference container, ensuring optimized signal injection.

United States Patent 4389888

Abstract:

According to a level meter of this invention, a pressure corresponding to a fixed water level formed by means of a reference chamber and a vertical pipe is applied to one pressure inlet port of a differential pressure detector, and a pressure corresponding to a water surface or water level inside a container to be measured is applied to the other pressure inlet port of the differential pressure detector by means of a lower pipe. Then, the water level inside the container is measured through the difference between these two pressures, the density of water to generate the pressures to be applied to the differential pressure detector, and the density of steam inside the container and the reference chamber. Adiabatic jackets are attached to the peripheries of the vertical pipe and the lower pipe

Filling Machine

United States Patent US2285627

Inline Bottle Filler




 

   The inline bottle filler is typical of a motion control application generally referred to as a flying shear. This application is common to several industries such as filling, cutting, punching, stamping, forming, labeling, and printing. Flying shear applications require work to be performed on a material while the material is in motion. A flying shear control must accelerate from a stop to match the speed of the moving material at a specific position, and then maintain synchronization of both position and velocity while the work is performed. After the operation is completed, the tool decelerates to a stop and returns to the start or home position. When the correct point on the moving material approaches, the process is repeated. The motion of the flying shear occurs within a fixed distance which cannot be exceeded, so the control must accelerate, track the material while the operation is performed, and decelerate within this distance at the maximum machine throughput.
