Systems and methods to measure fluid delivery times in a piping system and more particularly a dry pipe fire protection system. A device is provided that includes at least a solenoid valve for coupling to a network of pipes of a dry pipe sprinkler system and a liquid detector for coupling to the network of pipes to detect a flow of water in the network. A timer is coupled to the solenoid valve. Upon operation of the solenoid valve, the timer simultaneously initiates a start time of a fluid detection test. The timer is preferably coupled to the liquid detector such that upon the detector detecting water, the timer defines a stop time of the fluid detection test.
