No...that will not determine 'flow'.
You may have a stuck OPD valve.
Turn the cylinder off.
Remove, turn it upside down, then roll it slowly on the ground, reinstall and try it.
"OPD Valve Design
OPD valve looking at connection
The design of the OPD valve is such that turning the cylinder service valve handwheel will not produce any effect if the cylinder is not hooked up to an appliance. In other words, a connection must be made between the appliance hose end and the cylinders service valve. The inside of the OPD valve is engineered to only allow propane in or out if the internal valve is actuated by being depressed. This OPD valve feature adds additional safety in case the handwheel is turned, opening the valve. For this reason, OPD equipped cylinders will not allow gas out of the cylinder when opened. The same is true for industrial forklift cylinders."
If that doesn't work you may have a regulator problem.
