Meter provers are used to ensure that the proper amount of liquid hazardous materials is being loaded and or unloaded involving bulk packagings, such as cargo tanks and portable tanks. These meter provers consist of a gauge and several pipes that always contain small amounts of the liquid hazardous material in the pipes as residual material, and, therefore must be inspected and maintained in accordance with the HMR to ensure they are in proper calibration and good working order. These meter provers are not subject to the specification testing and inspection requirements in Part 178. However, these meter provers must be visually inspected annually and pressure tested every five years in order to ensure they are properly working as specified in § 173.5a of the HMR.
