Gas Stations

Gas pumpThe following tests are performed annually by Weights & Measures inspectors on gas stations in the City of Madison. The tests protect consumers and vendors by ensuring accuracy and reliability of equipment.

Inspectors will cover the following:  

General:

1. Verify that street/window signage has all products posted and they match the price on the pump. See Wis statute s.100.18(6) and s.100.18(8).

2. Fuel storage tank lids and twelve inches beyond the lid edge on the surrounding concrete should be painted with the correct color code for that type of fuel (refer to API
color codes).

Gas pumps: 

1. All displays are working and are readable.
2. Pumps have all required designations e.g. fuel grade, octane rating, and appropriate percent of ethanol in the gas or biodiesel in the diesel if over 5% in the blend.
3. All pump functions (keypads, printers, etc.) are in working order.
4. A visual check for the pump id plate with required make, model, serial number and NIST COC number (when applicable), security seal on the calibration mechanism, internal or external leaks and hose, breakaway, and nozzle condition.
5. Check each nozzle for a functioning auto shut-off

mechanism.

Pump operation/testing:

1. Pumps start at zero (no computer jump).

2. Accuracy of the pumps per NIST Handbook 44 (each grade/type of fuel) tolerances.

3. Meter creep (pump keeps incrementing after fuel flow has stopped).

4. Correct calculation of monetary value.

5. Verify the anti-drain valve does not allow fuel to drain out of hose once delivery is stopped.

6. Look for any skimming or fraud devices inserted into or attached to the gas pump.

Per chapter 22.06(4) Every owner or operator shall secure the gas pump(s) electronic and payment processing area(s) under their control or ownership by installing a lock(s) that is unique to the pump(s) under their control. This ordinance shall be effective January 1, 2017. (Cr. by ORD-16-00099, Pub. 11-9-16, Eff. 1-1-17)
