Why Would a 320 Amp Electric Meter Be Used on a 240V 100/200A Service Panel?

Hi, I'm not sure if I'm asking in the right place but here it goes.
I recently was made aware of a 320 volt electric meter being installed by our local utility company. My question is how does a 320 volt meter on a 100/200 amp panel with 240 volts coming in from the pole benefit anyone? I have seen 320 meters on much higher rated panels and they always have up to 2, 200 amp service breakers along with the 100 amp service disconnect breaker, and have the voltage to match coming in from the pole.

The one I was asked about was on a standard service panel, 240 volts coming in, and the electrician installed 2, 125 amp breakers bridged together for a 250 amp service disconnect. And that breaker was the only disconnect. The home is approx 62 years old, probably newer wiring, but has nothing in that home that would ever draw 125 let alone 250 amps to pop that breaker. Being they put a 320 volt meter in, wouldn't that cause even further issues if something was trying to pop the breakers? To me, this set-up is a fire just waiting to happen. Any thoughts would be appreciated.

A voltmeter will always be rated higher than the voltage (V) it is required to measure.
It only measures the voltage of the power supply, it does not change it.

A circuit breaker will always be rated higher than the normal current (I) that flows through it.
The current flowing through it is determined by the impedance (Z) of the circuit it is supplying. I = V/Z

The power company will fit circuit breakers outside a house that will never normally trip for a small overload, which should be taken care of by the lower rated fuses or breakers in the supply panel inside the house.

I believe we have a communication problem?

The meter I refered to is the meter the power company has at the service panel to meter useage. Not a meter to determine the voltage going through it. Its the meter the meter reader reads. Normal residential is 240 volts with a 240v meter, this one is 320 volts with only 240 volts coming in from the pole.

The service panel I refered to is the panel that meter is installed on which also has all the circuit breakers for the entire home within it.

The circuit breaker I refered to is the only main breaker (service disconnect) for the entire home, which is rated at 250 amps (125+125) which nothing in that home would ever draw nearly as much. Nothing much would draw 125 amps either to trip half that breaker. And I have no idea how the electrician wired those 2 125's, so if one side breaks, and the other continues to push power....................

What I'm seeing is a panel with a main breaker rated way to much for what the home draws even if a direct short occured. By having a 320 volt meter allowing more power to flow along with that high rated breaker, I don't see anything breaking to save electrocution and or fire. They may have GFI'S all over the place, but if they were wired incorrectly as the panel seems to be.........................

Is my line of thought correct? Or am I overthinking this?

What Frank said is applicable to your situation. The watt-hour meter that was installed will be rated at a higher voltage than what it's used on. As far as affecting the safety, that's what your 125A main breaker is for. Any over voltage protection would be on the utility side of the line.
Also, the two single pole 125 breakers ganged together do not make 250. If your 240V load in your house was high enough to reach 125A, for instance the dryer, electric furnace, welding receptacle, and whatever else, the breaker technically would be overloaded above 125A. What comes in, goes out.
If there are questions regarding the wiring of the GFCI receptacles, you can get a tester to check at your local hardware store. It's a little tough to mess the wiring up, unless they are on the same circuit in the kitchen and in the bathroom or something like that. It's easy enough to find out what circuit things are on by trial and error, flipping one breaker at a time. Or, if the electrician filled it out, look at the schedule(the list on the inside of the panel) to see.
Regardless, nothing stated really sounds out of the norm for the installation. The NEC states what can and can't be done, and if the install was done on the up and up, an inspector would probably catch any inconsistencies with the Code.
