How do I check the flow rate through a Sta-Rite Max-E-Therm 400? Is there a flow meter that I could install temporarily in place of the water pressure switch to check flow rate?

You can install a FlowVis in a Jandy check valve in your system.

No, you cannot convert PSI to flow rate. PSI varies with how clean or dirty your filter is.
What speed do you run the pump when the heater is on?
2400-2600 RPM should give you adequate flow for the 400K heater that needs at least 40 GPM.

Yes, you can convert PSI to flow rate with one of my spreadsheets.
However, there is some additional information required:
At what pump speed is that pressure?
Elevation from pool water to filter gauge?
Distance from pool to pump?
Suction side plumbing diameter and configuration (i.e. single line, parallel lines, etc.)?
Post a picture of your pump and plumbing setup on the pad.
I was able to determine that my Hayward Filter is model number is DE4820. I will have to look at the inside controller next time I am at the property in order to answer the rest of your questions. Over the past weekend I tore the heater down only to discover that both the bypass valve and thermal regulator had failed. I have replaced both and expect that to resolve the issue I was having but need to get a new igniter as I inadvertently broke the one I had installed while pulling it apart to do a visual of the heat exchanger (which is fine but I pressure washed it since I had gotten that far into it). As you can see from the picture an O-ring from somewhere else in the system got tangled up in the bypass valve and the valve fell apart upon removal.
