PSC 185.65 Accuracy requirements for meters. PSC 185.65 Note
Note: See AWWA Standards C-700 (Positive Displacement Meters), C-702 (Compound Meters), and C-701 (Turbine Meters).
PSC 185.65(2)
(2) Positive displacement meters shall have a percent registration between 98.5 and 101.5 within the range of normal test flow limits before being placed in service. In addition, new meters shall have a percent registration at the minimum test flow between 90 [95] and 101.5. In all other cases, the percent registration shall be between 90 and 101.5 before being placed in service. These requirements, in addition to flow, are shown in the table below.
PSC 185.65 Note
Note: It is the intent of the commission that new meters have an accuracy limits percent between 95 and 101.5.

PSC 185.65 Note* Section
PSC 185.73 (3) provides that at this flow rate the test quantity may be reduced to that equivalent to one-half revolution of the test dial. For the typical 5/8-inch meter the minimum test quantity would, therefore, be 5 gal. or 1/2 cu. ft.
PSC 185.65(3)
(3) Compound meters shall have a percent registration between 97 and 103 throughout the range of normal test flow limits. At flows within the change-over flow range, the percent registration shall not be less than 90%.
PSC 185.65(4)
(4) Turbine meters shall have a percent registration between 97 and 103 throughout the range of normal test flow limits and a percent registration of at least 95% at the minimum test flow.
PSC 185.65(5)
(5) For meter installations with remote reading devices the above accuracy requirements apply to the metering accuracy of the complete installation.

PSC 185.71 Meter testing facilities and equipment. PSC 185.71(1)(1)
Each utility furnishing metered water service shall own or provide, through contract or otherwise, adequate equipment and facilities to provide for testing all of its water meters in compliance with this chapter.
PSC 185.71(2)
(2) The meter testing facility shall, to the extent practical, simulate the actual service condition of inlet pressure and outlet pressure. It shall be provided with the necessary fittings, including a quick-acting valve for controlling the starting and stopping of the test, and a device for regulating the flow of water through the meter under test within the requirements of this chapter.
PSC 185.71(3)
(3) The overall accuracy of the test equipment and test procedures shall be sufficient to enable the testing of service meters within the requirements of this chapter and regulations. In any event, the inherent overall accuracy of the equipment shall permit tests with an overall error of not to exceed 0.5% at normal test flows and 1.0% at the stated minimum test flow.

PSC 185.72 Calibration of meter testing equipment. PSC 185.72(1)(1)
Volumetric standards shall be accompanied by a dated certificate of accuracy from an approved laboratory or agency. For any weight standard used, the scales shall be tested periodically by an approved agency and a record maintained of the results of the test.
PSC 185.72(2)
(2) A reference meter used for testing domestic or larger meters may be used only if the referenced meter has been tested and calibrated during the preceding 6 months. A record shall be kept of the 2 latest tests of any reference meter. (See also s.
PSC 185.73 (1).)

PSC 185.73(1)(1)
The test of any customer meter shall consist of a comparison of its accuracy with that of a standard of known accuracy. Where the test standard consists of a previously calibrated reference or service meter, the test results for the customer meter shall be adjusted to compensate for the inaccuracies of the reference meter at the particular flow rates.
PSC 185.73(2)
(2) A utility shall test a meter “as found," or before repair, and, unless the meter must be retained under s.
PSC 185.77 (3), “as left," or after repair.
PSC 185.73(3)
(3) The volume of water through the meter at each test flow point shall be sufficient to produce at least one revolution of the test dial except at the “minimum test flow" point when said volume of water shall produce at least one-half revolution of the test dial.
PSC 185.73(4)
(4) A meter not meeting the accuracy or other requirements of s.
PSC 185.61 or
185.65 shall, unless the meter must be retained under s.
PSC 185.77 (3), be repaired or rebuilt to meet those requirements before further use.

(b) Two test flows within the normal test flow limits, one to be approximately at the maximum registration and the other to be at a flow as high as practicable within the normal test flow limits.
PSC 185.74(3)
(3)
COMPOUND METERS. For each test it shall be determined whether or not the by-pass unit operates at the minimum test flow and, in addition, the percent registration shall be determined at each of the following test flows as determined from accuracy curves for the particular type and size of meter:

(b) A flow near the point of minimum registration within the change-over range;
PSC 185.74(3)(c)
