The principle of the magnetic flap level gauge
Thread Content
I would like to ask the experts: What is the principle behind magnetic flap level gauges? Is it related to the density of the substance? Some flap level gauges have density requirements specified on their nameplates! Does the flap not float when the density is insufficient? Thank you
1. There is a magnetic float inside the cylinder; as the liquid level rises, the color disc flips, thereby indicating the liquid level height. 2. There are density requirements, as the buoyancy of the float varies depending on the medium
Float balls are customized specifically for the medium. If the medium is changed, using the original float may result in inaccurate measurements
There is a float inside the barrel, and different floats are used for media with different densities. The float is magnetic; as it rises and falls, magnetic force is used to cause the colored small balls on the outside to rotate.
Reply to 5# paul688688: So, in situations where the density changes, such as in a three-phase separator, can a magnetic flap level gauge be used? Thank you
It should be related to density. I wonder if the poster has used a hydrometer; it works on the same principle – if the density of the medium changes, it can no longer be used.
The working principle of the magnetic flip-type level gauge is based on the U-tube principle. When the liquid level inside the device changes, the liquid level within the magnetic flip columns also changes in sync with it. The float inside the level gauge is magnetic; as the liquid level changes, the height of the float changes as well. The magnetism of the float causes the magnetic flip columns (i.e., the red and white columns visible on the outside of the level gauge) to change as well. The density of the medium determines the size of the float.
