Melting temperatures <400°C
Emptying the container for non-ferrous metals up to a melting temperature of 400°C. Emptying of containers with liquid molten metal is always a critical process and can be a safety risk. Precimeter has developed a pump system with a round pump that makes the process controllable and safe.

Melting temperatures <800°C
For stationary, non-tilting melting furnaces, there is often the need to cover large distances in order to tap the molten mass in conjunction with considerable mechanical effort, which under certain circumstances influences the statistics of the furnace and the building. In order to automate removal of the molten mass, Precimeter GmbH has developed a system based on an electromagnetic pump (flat channel pump).
Two inductive sensors (PLP) and a special electronic system were developed in order to be able to supervise filters.
A difference signal is processed by the measuring electronics to allow supervision of the process cycle.

Filter monitoring 2
Two inductive sensors and two electronic systems were developed in order to be able to supervise filters. The changing levels, seen in the following example, are measured before and after the filter. The sensor signal before the filter can be used to control a tilting furnace. The sensor signal after the filter activates the alarm for a filter change.
As an alternative to electric probe scanning, Precimeter offers a purpose-built inductive sensor (PLPR) to allow positioning of the exact operating point of the ladle.
With a laser sensor different processes can be controlled and monitored during channel filling, such as tilting furnace or plug control.

Closed systems
Using an inductive sensor (PLP) and the appropriate electronics, different processes can be controlled and monitored during channel filling, such as tilting furnace or plug control.
To influence the process of low pressure pouring, a ring probe (RP) was designed by Precimeter. The Ring probe is positioned over the riser tube, so that during an increase in pressure the rising melt reaches the area of the ring probe at a pre-programmed point of reference. This point is used for the start of the casting process.
The continuous dual submersed sensor (CLP) Precimeter GmbH was developed for applications typically found in electrolysis. Two super- imposed levels can be measured, e.g. aluminium / salt or magnesium / salt.
Since it is well known that very aggressive chemical reactions take place during electrolysis processes, it is essential to select an appropriate protective tube for the submerged sensor.
For an open crucible, furnace or well the laser triangulation sensors are a good solution for measuring the level without any contact with the melt.

Closed Systems
In closed chambers or pressurized furnaces the inductive sensors can provide continuos reading or function as a High level or fully charged indication.
