§ 61.20. Meter tests.
(a) Allowable error for condensation meters. No condensation meter may be placed in service or allowed to remain in service which has an error in registration of more than 4% when the temperature of the condensate is standard (140° F) and the average water flow through the meter is approximately equal to the manufacturer’s rating of the meter.
(b) Allowable error for flow meters. No steam flow meter may be placed in service or allowed to remain in service which has an error in registration of more than 4% when the steam, at its average moisture content, nominal pressure and average steam flow through the meter or its differential pressure-producing device, is approximately equal to the manufacturer’s rating of the meter or its differential pressure-producing device.
(c) Periodic tests. A public utility shall make periodic tests of meters in service in accordance with the following:
(1) Condensation meters shall be tested at least once every 24 calendar months.
(2) Steam flow meters shall be tested at least once every 3 years.
(3) Meters shall be sealed or capped after the completion of periodic tests.
(d) Meter records. A public utility shall maintain a record of each customer meter. This record shall show the name of the manufacturer, type, rating, date of purchase and date installed in service, location and removal date, date and reasons for tests, and the error before and after testing, indicated by the words ‘‘as found’’ and ‘‘as left.’’ This record shall be kept for 6 years.
(e) Installation test. A steam service meter installed shall be tested for accuracy by the public utility before its installation, or shall be tested within 12 calendar months after installation. It shall also be inspected by the public utility for proper connection, mechanical condition, and suitability of location within 60 days after installation.
(f) Request test. Upon payment of the fee specified in § 1.43 (relating to schedule of fees payable to the Commission), each public utility shall make a test of the accuracy of registration of any service meter if a written request is made by the customer for whom the meter is installed. A customer may require the seal of the meter to be broken in his presence or that of his representative if he desires personally or by a representative to witness the testing of a meter. The fee shall be retained by the utility if the tested meter is found to be accurate within the limits specified in subsections (a) or (b). However, the cost shall be borne by the utility and the fee returned to the customer if the tested meter is found to be inaccurate. A report of the test shall be made to the customer.
(g) Fees for testing appliances of public utilities. For testing the measuring apparatus and condensation meters of public utilities the Commission will charge and collect from such utilities the following fees:
(1) For a testing facility tested at the plant of a company—$15.
(2) For a condensation meter tested at a Commission laboratory—$3.
