There is a magnet at the end of the OPD valve inside the tank. This corresponds with a magnet located on the back of the gauge itself. As the valve goes up and down indicating the level of propane, the magnetic field also moves the needle up and down to show the levels on the gauge.
There is a magnet at the end of the OPD valve inside the tank. This corresponds with a magnet located on the back of the gauge itself. As the valve goes up and down indicating the level of propane, the magnetic field also moves the needle up and down to show the levels on the gauge. So if you remove the gauge, it will not work with another tank since there will be no magnet inside the valve to indicate the levels of propane to the gauge.
