Section 500.4 - Testing equipment

(a) Each water-works corporation, unless specifically excused by the commission, shall provide for and have available such meter testing laboratory or shop, standard meters, instruments, and other facilities as may be deemed necessary by the commission properly to make the tests required herein. Such equipment and facilities shall be acceptable to the commission and shall be available at all reasonable times for inspection and use by authorized representatives of the commission. Water-works corporations may co-operate in arranging for meter testing facilities. Tests for accuracy of such equipment will be made at such intervals as the commission may deem necessary.

(b) Requests to be excused from the provisions of subdivision (a) of this section will be considered from water-works corporations having less than 100 meters in service when satisfactory arrangements are made for testing of meters at approved laboratories; or from companies which arrange for all facilities prescribed herein at approved locations elsewhere than on the premises of said company.

(c) The minimum equipment required for registration tests is as follows:

(1) A quick-acting valve on the discharge pipe through the use of which the flow can be started and stopped without appreciable loss of time.

(2) A valve and an orifice attachment on the outlet side of the meter, either of which can be used to establish the rate of flow desired.

(3) Pressure gauges connected on both the inlet and outlet of the meter to show whether any material change in pressure occurs during the period of test, which would affect the rate of flow. The outlet pipe is to have sufficient head on it so that the meter will always have pressure on its outlet end and preferably not less than five pounds per square inch.

(4) A measuring device which may be either of the volumetric or weighing type. Whichever is used, the accuracy of determination of the volume or weight of water discharged into the measuring device must be such as to bring the limit of error within one quarter of one percent.

(5) It is desirable to have available for testing meters a test table and appurtenances which are manufactured by several concerns. Such an outfit would include the equipment enumerated in the preceding four paragraphs.
