# PSC 134.28 Meter testing. **Citation:** Wis. Admin. Code § PSC 134.28 **Type / status:** regulation / current **Agency:** Public Service Commission of Wisconsin **Effective:** 1989-12-01 **Published:** Not stated Complete current PSC 134.28 from official Wisconsin Legislature sources (gas-utility-service). ## Document text PSC 134.28 Meter testing. (1) Each meter test of a diaphragm type meter with a capacity of 2,400 cubic feet per hour or less shall consist of one proving at a rate of flow of 15 to 30% of the rated capacity of that meter and one proving at a rate of flow at 90 to 120% of the rated capacity of the meter. The capacity of the meter for test purposes shall be the capacity at one-half inch water column differential pressure. (2) Each meter test of a diaphragm type meter having a capacity greater than 2,400 cubic feet per hour shall consist of one proving at a rate of flow of 15 to 30% of the rated capacity of that meter and one proving at a rate of flow of 90 to 120% of the rated capacity of the meter but not less than 2,500 cubic feet per hour. The capacity of the meter for test purposes shall be the capacity at one-half inch water column differential pressure. (3) Rotary meters shall be tested at 2 loads with the minimum load at 10% of rating by the use of a portable or volumetric meter or other approved proving devices, or be given a differential test. In the latter case an original test record shall be set up immediately after installation; future differential test results shall be recorded and compared with the original test record. (4) A test of an orifice meter shall consist of tests of the recording gauges, and the removal, inspection and measurement of the orifice. (5) Temperature-compensated gas displacement meters when tested shall be proved to a base temperature of 60° Fahrenheit. (6) Turbine-type meters shall be tested at 2 loads with the minimum load at 10% of rating by the use of a portable or volumetric meter or other approved proving devices, or be given a turbine blade, rotor and gear assembly spin test, either by manual or velocity rotation. Before a particular type turbine meter can be used, the manufacturer must file with and be accepted by the commission a minimum coasting time which will satisfactorily indicate the operating condition of the internal metering mechanism. For the spin test method a test record shall be set up; and the original and subsequent spin test results shall be recorded and compared with the specified minimum coasting time as filed with the commission for that type meter. ## Provenance - Official: Yes - Source: - Source ID: `wi-legislature-pipeline-corpus` - SHA-256: `a7ee37175aac09de5d7f1450758cb5d4ed7c8e57320c8b9f227a64cdbb63b9f3` - Retrieved: 2026-08-12T06:25:04.554Z - Exported: 2026-08-22T21:17:26.406Z - Document slug: `wi-psc-134-28` ### Source metadata ```json { "jurisdiction": "US-WI", "code": "Wisconsin Administrative Code", "chapter": "PSC 134", "section": "PSC 134.28", "category": "gas-utility-service", "currentThrough": "2026-08-01", "currentnessBasis": "Official publisher states the entire administrative code is current and updated on the first day of each month.", "legalScope": "This completeness-verified corpus contains every current section of Wisconsin Administrative Code Chapters PSC 133, 134, and 135, plus complete Wis. Stat. §§ 196.745 and 182.0175. Chapter PSC 135 is the dedicated gas-safety chapter. Chapters PSC 133 and 134 are included because the Wisconsin PSC identifies all three chapters as requirements used in pipeline-safety inspections; they also contain broader construction, siting, utility-service, billing, metering, and customer provisions.", "applicabilityCaveat": "Applicability depends on Wisconsin PSC jurisdiction, operator and facility type, intrastate or interstate status, gas-public-utility status, project thresholds, activity, exemptions, waivers, Commission orders, federal preemption, and the specific provision. Wis. Stat. § 196.745 excludes propane distribution systems from the PSC pipeline-safety program, while the one-call law reaches transmission facilities beyond natural-gas pipelines.", "incorporationCaveat": "Chapter PSC 135 adopts and supplements federal minimum pipeline-safety standards, principally 49 CFR Parts 191, 192, 193, and 199. The source also cites statutes, administrative rules, Commission forms and orders, and private technical standards. References are retained as metadata; incorporated material is not reproduced and its edition, legal effect, and licensing must be verified at the referenced source.", "rightsCaveat": "Official Wisconsin Legislature and Public Service Commission text is preserved with attribution and source hashes. Public availability does not establish a blanket license for site presentation, agency marks, annotations, forms, or incorporated federal and privately authored standards; downstream redistribution requires separate rights review.", "history": "History: Cr.
