6 8. Stow the drained professional hose, secure the provers with the (3) locking brackets making sure to replace the cotter pins and replace vapor caps. Conducting a Proving Run with the 50 Gallon Series J Prover: 1. Close the Series J prover drain cock. 2. Perform the wet down procedure on the prover. Prover Wetting Procedure :1.If the prover is clean and free of debris, fill the prover with liquid from the meter device being 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. 2.Open the prover drain valve to drain the prover into the underground storage tank through the gravity drain line. Once the cessation of main flow breaks, as viewed through the sight flowmeter, wait 30 seconds and then close the drain valve. 3.The prover is now wet down and is ready for an official test. Testing Procedure: 1.Record the meter register, or zero the prover industrial counter if one is being used. WARNING: The prover 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.If a flammable liquid is being tested, ensure the prover is grounded to a proper earth ground using a grounding cable and clamp (to eliminate static electricity build-up). 3.Check and adjust the leveling device(s) to ensure that the prover is level and verify that the prover drain valve is closed.
