Will this expansion valve work for what I want to do?
Sporlan Thermostatic Air Conditioning Expansion Valve FV 1 2 C R22 | eBay
It's rated at 1/2 ton.
I'd like to just setup everything with flared connections to begin with so I can change out parts easily while I experiment. It should be super simple plumbing - Compressor > Condenser coil > Filter > TxV > Evap coil > Compressor again.

Why not use a simple inexpensive flowmeter? Then you just measure the fluid temperature (easy to do) and record the water flow rate.

Initially there won't be anything flowing but refrigerant. I know the water will stratify, but I would like to test that too. When I add some water pumps, that would be nice to add as well.
I could estimate the BTU loss through the drum by filling it up with warm water, letting it sit for an hour, and measure the temp.
