Measuring Devices

The Measuring Devices Program assures accuracy of commercial transactions based on quantities by spot inspections of establishments involved in bulk sales, by test purchases of commodities, and through investigations of complaints.

Some of the Measuring Devices we check:

Electric Sub-meters: sub-meters are installed in establishments which purchase electric service from a serving utility by a master meter and distribute the service to tenants through a sub-metered service system.
Fabric, Cordage, Wire: mechanisms and machines designed to indicate automatically the length of cordage, rope, fabric, etc. as it is threaded through the measuring elements.
Grease & Lube Meters: a device designed for the measurement and delivery of liquid lubricants (automotive). Devices such as Auto Lubes.
Liquified Gas Meters: a device used for the measurement of petroleum gas in the liquid state, whether such devices are installed in a permanent location or mounted on a vehicle. Devices such as propane tanks.
Retail Motor Fuel Meters: a device designed for the measurement and delivery of liquid fuels. Devices such as gas pumps.
