Most meters are in common ground design. The volt meter is able to monitor it's own supply voltage simply by connecting the "+" input to the power (+) terminal and leave the Negative (-) unconnected.
For an amp(current) meter, you got to be careful about the looping feedback from the shunt. To avoid the problem, you better to install a dc-dc isolated power module to provide it an independency power to the meter
