Section 211 - Meters and measuring appliances(a) The Commission may, after hearing, by order in writing, establish reasonable rules, regulations, specifications and standards to secure the accuracy of all meters and appliances for measurements and may provide for the examination and test of all appliances used for the measuring of any products or service of a public utility.(b) The Commission may enter, by and through its agents, experts or examiners, upon any premises occupied by any public utility for the purpose of making the examination and tests provided for in this section and may set up and use on such premises any apparatus and appliances necessary therefor.(c) The Commission may fix the fees to be paid by any consumer or user of any products or services of a public utility, who may apply to the Commission for an examination or test to be made of the meters or other measuring appliances of the utility. If the meter or other measuring appliance so tested shall be found to be accurate within such commercially reasonable limits as the Commission may by general or special order fix for such meters or class of meters or other measuring appliances, the fee shall be paid by the consumer requiring such test, but if not so found then the cost thereof shall be borne by the public utility furnishing the meter or other measuring appliance.(d) All measuring devices installed subsequent to June 28, 1974, for the purpose of ascertaining bills presented by and on behalf of public utilities providing steam, manufactured gas, natural gas, electric light, heat, power and water shall be installed in a manner permitting readings from the exterior of the customer's premises. All such public utilities having measuring devices that, as of June 28, 1974, permit only readings from the interior of the customer's premises shall, when so requested in writing by the owner of said premises, substitute measuring devices permitting exterior readings, said substitution to be effected at cost payable by the owner. 47 Del.
