There is a sending unit laocated at the fuel pump that sends info to the gas gauge. This can malfunction with no reason at all. I am betting that this is the reason since your gauge still moves. If the gauge is bad usually it wont move at all and is not a common thing now a days anyway. The sending unit is more common. Hope this helps.
The Pirani gauge is base on a heating element that is cooled due to the thermal conduction of the measured gas. The heating elements resistance drops as the thermal conduction is increase i.e. more gas results in a drop in resistance. On the other hand less gas results in less conduction increased temperature of the heating element and increased measured resistance. This is a very robust gauge and is suitable for relatively high pressures, down to 10^-4 Torr. Below that you need a different gauge as the low number of gas molecules does not allow any measureable change.
it tells you volume, which is directly related to mass
the screw gauge is an instrument which is used to measure length of an object.... the least count of an screw gauge can be found as follow.... l.c= pitch of the screw gauge no of divisions on main scale
Argon gas is used in windows.

The gas gauge is in the instrument cluster , the sending unit for the gas gauge is inside the gas tank combined with the electric fuel pump
my gas gauge is not working what could be the problem
The gas gauge and fuel pump are on two separate circuits tand both go inside the gas tank. The gas gauge usesf a float that moves a resistor according to fuel level. Gas gauges. When you experiewnce the gas gauge not working at all I would look for a disconection external to the tank first. If you cna send six volts from the tank sender to the gauge this should cause the gauge to read. If it does then you know the problem is with the sending unit and it must be removed from the tank to repair or replace.
If the gas gauge stops working is there a fuse for it?
your gas gauge float is in the gas tank you have to drop your gas tank and take out sending unit but if the gas gauge is not reading right you should check the ground wire on the gas tank
Pull the gas tank and replace float but check all wires to the tank first
Check the fuses first!
The fault could be the sending unit or the dash gauge.
Tungsten Inert Gas (TIG)
It is a gas tank fuel level gauge that operates without the use of electronics.
you need to replace the gas gauge sending unit in the tank, or your gauge is broken
