For this purpose, a municipality shall establish a municipal department of weights and measures. Each municipal department of weights and measures shall have such number of qualified sealers or inspectors as will ensure compliance with this chapter. Municipal sealers or inspectors shall have the same authority as sealers or inspectors of the department of agriculture, trade and consumer protection. The selection of municipal sealers or inspectors shall be from a list of applicants whose qualifications have been certified by the state or local civil service agency under the rules of the agency. The municipality shall procure and keep at all times a complete set of standards of weight and measure conforming to the state standards and shall submit the standards for certification at regular intervals as required by the department of agriculture, trade and consumer protection. The municipality shall keep a complete record of its work and annually shall file a report thereof with the department of agriculture, trade and consumer protection.

The department of agriculture, trade and consumer protection may charge the municipality fees sufficient to cover the department’s costs under the contract. A municipality may recover an amount not to exceed the cost of these fees by assessing fees on the persons who receive services under the weights and measures program.
