Diaphragm Type Gas Displacement Meters (under 500 Cubic Feet Per Hour Capacity) Fourth Edition

This standard applies to diaphragm-type gas displacement meters, designed for revenue measurement of fuel gas, having a flow rating of less than 500 cubic feet per hour (14.16m(3)/h) capacity at 0.5 inch water column (125 Pa) differential pressure at standard conditions. Part I comprises a list of definitions and terms used throughout the standard. Part II covers the construction requirements for qualifying new-type meters in the designated flow-rate ranges. Part III covers the performance requirements for qualifying new-type meters in the designated flow-rate ranges. Part IV covers the "in-service" performance requirements for diaphragm-type meters in the designated flow-rate ranges. Part V addresses installation requirements for these meters. Part VI pertains to auxiliary devices used with gas meters covered by this standard. Part VII covers test methods and equipment.

Self-Operated Diaphragm-Type Natural Gas Service Regulators

This standard shall apply to the minimum design, material, performance and testing requirements of 1 1/4 inches (32 mm) and smaller self-operated diaphragm-type natural gas service regulators operating at inlet pressures up to 125 psig (861.8 kPa). These regulators are used to control the gas delivery pressure to pressures at a maximum 14 inches water column (3.48 kPa). This standard shall apply only to regulators manufactured after the approval date of this standard.
