PSC 134.30(2)(2) All diaphragm meters that are measuring dry gas that do not have non-absorptive-type diaphragms and have not been rediaphragmed since the introduction of dry gas shall be removed from service, tested, adjusted, re-diaphragmed and retested within 48 months of the introduction of dry gas if the meter capacity is 2,400 cubic feet per hour at 1⁄2-inch water column and within 24 months if the capacity is greater than 2,400 cubic feet.

PSC 134.30(3)(3) All diaphragm meters that measure other than dry gas shall be removed from service, tested, adjusted, repaired, if necessary, and retested if reused every 96 months if the meter capacity is 2,400 cubic feet per hour or less at 1⁄2-inch water column and every 48 months if the capacity is greater than 2,400 cubic feet.

PSC 134.30(4)(4) Rotary meters having a capacity of 15,000 cubic feet per hour or less at 4 oz. water column pressure shall be given a differential test at least once every 96 months and once every 48 months if the capacity is greater than 15,000 cubic feet. When the differential differs from the original test record by more than 50%, the meter shall be cleaned and/or repaired.

PSC 134.30(5)(5) Orifice meters shall have their differential and static recording gauges tested at least once each month, the diameter and condition of the orifice checked at least once a year. The specific gravity of the gas shall be checked as required in s. PSC 134.21 (4), and any temperature recording devices tested annually.

PSC 134.30(6)(6) Turbine meters shall be given an inspection and spin test at least once every 12 months. When the coasting time is equal to or less than the specified minimum coasting time as on file with the commission, the meter shall be cleaned and/or repaired.

PSC 134.30(7)(7) Turbine meters which are capable of automatically adjusting shall be inspected and tested at least once every 12 months. They shall be tested in accordance with s. PSC 134.28 (6) or with the use of the meter manufacturer’s electronic field prover.

PSC 134.30(8)(8) Whenever an automatically adjusting turbine meter automatically adjusts the volume for plus or minus 5% or more while in operation at a steady flow rate of 10% or more of the meter’s rated capacity, the meter shall be cleaned and/or repaired.

PSC 134.30(9)(9) Whenever an automatically adjusting turbine meter is being tested at a steady flow rate of 10% or more of the meter’s rated capacity and indicates an error of plus or minus 1% or more, the meter shall be cleaned and/or repaired.

PSC 134.31(1)(1) Each utility furnishing gas service shall make a test of the accuracy of any gas meter upon request of the customer, provided the customer does not request such test more frequently than once in 6 months. A report giving the results of each request test shall be made to the customer and the complete, original record shall be kept on file in the office of the utility. A customer or group of customers may not abuse the request test procedures. Abuse shall be determined by the commission.

PSC 134.31(2)(2) Any gas meter may be tested by a commission inspector upon written application of the customer. For such test, a fee shall be forwarded to the commission by the customer with the application. The amount of this fee shall be refunded to the customer by the utility if the meter is found to be more than 2% fast as determined in s. PSC 134.14 (1). The amount of the fee that is to be remitted for such tests shall be $5 for each consumption meter that has a rated capacity not exceeding 1,000 cubic feet per hour; for larger consumption meters, demand meters, etc., the test fee shall be the actual expense of the test.

PSC 134.31(3)(3) All referee meter tests shall include an inspection of the meter index by removing the index from the meter body. The dials, gears and all other parts of the index shall be visually inspected for wear, misalignment or other mechanical defects which would affect the accuracy of the meter on a continuing or sporadic basis. Any defects affecting the meter’s accuracy shall be noted and evaluated in the report of the test.

PSC 134.31(4)(a)(a) After a customer requested test. When a utility performs a customer-requested test on a customer’s meter under sub. (1) or when the commission requests that a meter be tested, the utility shall keep the tested meter, in “as tested” condition, at a designated location on the utility’s premises for at least one full billing period plus four weeks after the test result report is issued so that the meter is available should another meter test be requested. If the meter tests as accurate, the utility may choose to keep the tested meter installed at the customer’s premises for the designated time period rather than storing it at the utility’s premises.

PSC 134.31(4)(b)(b) After a referee test. When a utility performs a referee test on a customer’s meter under sub. (2), the utility shall keep the tested meter, in “as tested” condition, at a designated location on the utility’s premises for at least 10 business days after the test result report is issued so that the meter is available should further testing or review be needed. If the meter tests as accurate, the utility may choose to keep the tested meter installed at the customer’s premises for the designated time period rather than storing it at the utility’s premises.

PSC 134.31(4)(c)(c) When a complaint or dispute occurs. When a utility receives a complaint under s. PSC 134.17 or is notified about a dispute under s. PSC 134.064 involving meter accuracy, the utility shall keep the meter, in “as tested” condition, at a designated location on the utility’s premises for at least one full billing period plus four weeks after the complaint or dispute and any appeal of that dispute is resolved so that the meter is available should testing be requested. If the meter was tested during the complaint or dispute process, and it tested as accurate, the utility may choose to keep the tested meter installed at the customer’s premises for the designated time period rather than storing it at the utility’s premises.
