Can a 3x20(80A) energy meter handle 22kW (3x32A)?

Question

I'm installing a 22kW EV charger that draws 3x32A and I want to have an energy meter to see how much the cars are using. The energy meter I was told was ok is a B+G DRT428DC-V3, but now when I'm about to install it I'm doubting that is correct.

It says 3x20(80A) on the front. I've been told that it means that each phase should be able to handle 80A, so in total 240A, which should be more than enough to cover the total of 96A that I need.
However, the big question I have is whether the 80A is per phase or the combined maximum of the three phases?
Is the 3x20(80A) energy meter powerful enough to handle 22kW (3x32A)?

The 20A rating is the basic current as defined in IEC 61036.
This is the nominal value for the other specifications, this is valid up to the maximum 80A.
Outside those limit increases the error.

I've received answer back from the manufacturer.
'yes, you can use the device with a 22kW wallbox. The device can work with continuous loads of up to 80A per phase, so there is still enough space above.'
