Monitor process RAM usage?

Question

PowerShell

Task: start the process and track the amount of RAM allocated for this process.
Everything is done in PowerShell.
The script is like this:

$process = new-object System.Diagnostics.Process;
$process.StartInfo.filename = "[путь к exe]";
$process.Start();
write-host $process.WorkingSet;

The problem is this: if the process runs for 2-4 seconds (or does not end at all), then the correct amount of memory is returned. If the process starts and immediately ends, then WorkingSet returns 0. How to deal with this?
