1. What is a float level gauge?

En float level gauge measures the height of the liquids present in the vessels, depending on their floating displacement. The connection of the float is with the measuring tape that rises and falls is dependent on the changes of the liquid present in the tank. Whenever the liquid level rises, the float also rises according to it, and the tape’s connection is with the spring drum that gets a twist. Whenever the liquid level starts to fall in the vessel, the float keeps dropping, and the tape pulls by the weight of the float. The movement of the float is transmitted towards the point-scale plate or counter by the gear mechanism.

The float type level switch starts when the float keeps moving up and down due to the buoyancy. The reed switch present in the stem works by the magnet in the float, and output detects the signals. Moreover, sometimes the level meter cannot measure the level of the liquid with some of the viscosities and specific gravities. There is some situation when there is no possibility for the measurement. For example, you can measure the levels of high viscous liquids. The float stops working when the pressure in the tank is high or the specific gravity of the liquid is low. There are some solutions available to resolve these issues. The first solution is surface processing.  Electrolytic grinding and buffing are present for the surface processing, and other solutions specify the high temperature. You can use the float type level switch approximately to 160 degrees Celsius, and the option of increasing the pressure is also available.

17. What is the measuring range of the float level gauge?
