Sealing Fuel Dispensers
The Weights and Measures department is responsible for regulating the accuracy of fuel dispensers (fuel volume). The weights and measures inspectors examine fuel dispensers at each service station and fuel depot in Memphis annually.
Checking Fuel Volume
Recording Fuel Volume
Inspectors pump fuel into a certified test container to check for the accuracy of the amount of product delivered by the dispenser.
Inspectors place an approval sticker (seal) on the dispenser, if the dispenser passes the inspection. If the dispenser does not pass the test, the department will take enforcement actions to ensure the dispenser is repaired and recalibrated before it can be placed back in service.
Service stations and fuel depots are required to maintain their equipment. The outcome of our inspection is to ensure all devices are accurate and correct. Weights and Measures do not regulate gasoline prices.

The Weights and Measures department performs UPC scanner audits annually in stores that utilizes the electronic scanners. The department randomly conducts audits at grocery, convenience, department, drug, and auto parts stores.
Many stores use electronic scanners to read the price at the checkout counter. These scanners are linked to a computer that reads the Universal Price Code (UPC) on the product or tag and corresponding price that has been loaded into the computer. Often, this preloaded price does not match the price posted on the item or self.
The Weights and Measures inspector conducts scanning accuracy audits by:
- Randomly selecting a specific number of items.
- Recording or scanning the posted price or price on the package.
- Proceeding to the checkout counter, scanning the UPC of each item and watching the display to make sure the scanned price matches the posted price or the price on the package.
- If items fail the audit, the store manager is notified and the problem must be corrected immediately.
The Weights and Measures department performs package checking (checking net contents of goods) audits annually. These audits are conducted on stores where items are weighed and packaged. i.e. grocery stores, delis, and meat counters.
The Weights and Measures inspector performs this audit by:
- Checking the accuracy of the scale that weighed the product.
- Verifying the tare weight (packaging material) used in packaging the products.
- Randomly selecting products in produce, meats, and the deli.
- Weighing the product to obtain the gross weight.
- Subtracting the tare to get the net weight.
- Perform statistical calculations to determine if the lot of products pass or fail.
- If products fail, the department and store manager is notified of the results. The store takes the necessary corrective action by re-weight all the products effected in a lot.
