Generally we use Cv value of the regulator to size the relief valves. But not sure how to size relief valves for flow meter regulators since it comes with a preset pressure. Any help on difference between a flowmeter regulator and a standard pressure regulator would be very helpful. Is Cv value not applicable to flowmeter regulators since they come with a preset pressure? Does the orifice size remain constant?
Any help will be greatly appreciated, thanks!
