3 Description: Set-up Procedure for calibration with 5 gallon/20 liter Special J prover: The Seraphin
® Gasoline Calibration (Box) Professional trailer is a mobile proving system designed tocalibrate gasoline dispensers. It is comprised of (3) precision volumetric stainless steel bottom drain provers connected each to their own individual 115 gallon holding tank in the rear of the totally enclosed trailer. The prover drain valve is plumbedto piping that can be routed via butterfly valves manufacturers to a gravity drain. Five (6) six-foot hoses are supplied to help empty the tanks back into the storage facility tanks. 1.Electrically ground the unit, to a proper earth ground, using the 50 ft. of grounding cable enclosed in a retractable reel which is mounted on the deck. Also, check to see that the grounding strap from the prover to the tank is secure. This will dissipate any static electricity that could be generated during the filling of the prover. WARNING: The prover/trailer system must be properly grounded prior to conducting petroleum measurement testing to prevent possible static electricity from sparking which could ignite a flammable product. Follow all safety measures. 2.Remove the (3) cotter pins from the locking bracket and slide the “U” bracket out so that the provers can be free standingand able to be leveled individually. 3.Close all 3 prover drain cocks and 3 holding tank gravity drain valves. 4.Remove the Vapor Cap from the top of the prover neck, exposing the neck opening. 5.Visually inspect, from the top neck opening, the interior of the prover to ensure it is free of debris which could affect the accuracy of the liquid volume measurement. Prover Wetting Procedure :1.If the prover is clean and free of debris, fill the prover with liquid from the meter devicebeing checked. Fill the prover until the amount on the meter reads the nominal capacity of the prover. NOTE :The prover must be filled once and drained in order to wet the internal sides of the prover body. Wetting the internals of the prover helps ensure consistency in the amount of liquid that clings to the sides, from one test to the next.
