Split Compartment Test (Continued)
With a quick-connect coupling:
1). During a normal full flow test run; close the compartment valve at approximately one-half of the
nominal prover capacity. Then slowly and carefully disconnect the quick-connect coupling,
allowing the pump to drain the supply line.
2). Continue the test until the meter indication stops entirely for at least 10 seconds. If the meter fails
to stop entirely for at least 10 seconds, continue to operate the system for 3 minutes.
3). If the meter stops for at least 10 second or after 3 minutes, close the delivery nozzle or valve at the
end of the delivery hose if top filling.
4). Disconnect and reconnect the quick-connect coupling and open the compartment valve.
5). Carefully open the nozzle or valve at the end of the delivery hose. Pockets of vapor or air may
cause product to splash out of the prover. The test results may not be valid if product is splashed
out of the prover. Appropriate attire and protection is required, but caution is still necessary.
6). Continue the delivery of product at the normal full flow rate until the liquid level in the prover
reaches the prover’s nominal capacity.
7). Close the delivery nozzle or valve, stop the meter, allow any foam to settle, then read the prover
sight gauge.
8). Compare the meter indication with the actual delivered volume in the prover.
9). Calculate the meter error, apply Product Depletion test tolerance, and determine whether or not the
meter error is acceptable.
Tolerance for Vehicle-Tank Meters
Meter size Maintenance and Acceptance
2” (50 mm) 137 cubic inches
3” (75 mm) and larger 229 cubic inches
The results of the product depletion test may fall outside of the applicable test tolerance as this is a
stand-alone test.
The test draft should be equal to at least the amount delivered by the device in 1 minute at its maxi
mum discharge rate, and in no case should it be less than 50 gallons.
