Vehicle Tank Meters
If your operation has vehicle tank meters (VTMs) they must be tested annually to ensure accurate delivery of fuel products.
Be prepared for the following tests:
Split Compartment Test: Driver dispenses 20 gallons of product and then switches to dry tank. A dry break is used if no dry tank is available. The inspector waits 10 seconds after meter stops. If the meter does not stop, the inspector waits three minutes and continues the test by reattaching the hose to the full compartment and filling the prover to capacity.
Preset Test: Test is done while pumping back the last test draft. Zero the meter and set the preset for 20 gallons. Start the flow and let the preset stop the meter. It should stop within a ½ interval on mechanical meters and there should be no error on digital meters.
A ticket will be printed and checked for each meter. Zero and the full draft amounts must be readable.
Drivers can calibrate devices as needed. Correct meters are sealed and a sticker is applied.
Alternatively, a private service company can calibrate the meter. Reinspection by the City of Madison is required.
Your company is responsible for sending the City test report to:
