Abstract: Well directed cooperation often brings about accomplishments of great value and many of the most impressive achievements in the gas industry have come from close cooperation between the manufacturer and engineers who use thier products. The situation, particularly in this instance with a survey conducted by the Sprague Meter Company and gas distributor companies, has resulted in bringing to the gas industry, after five years of experimental research and actual practice, a pressure control and measurement instrument well advanced in modern design as the new 747. This new development is a 175RM Regulator/ Meter. This meter is not new to the gas industry, but what makes it unique is the increased size of the service regulator and the vertical position of the regulator unit concealed in the back of the meter unit and out of sight of meter installation. See Figure No. 3. Compare Figure #1 with Figure #2 -you can see that this new class 175RM is truly the new look set for the 70s. Note the bottom inlet, the back outlet features which was industrys response to the survey, indicating a basic desire to simplify this use of piping with the outlet concealed. Figure #3. This 175RM unit is offered in a positive vertical drains screened vent available only as an internal relief type, stainless steel relief spring that will relieve approximately 8 w.c. above set pressure. Orifice sizes from 1/8 to 5/16 are available with the regulator to control inlet pressure to 125 p.s.i.g. to an outlet pressure range of 5 of water column to 2 p.s.i.g. Adjustment of regulator pressure is accomplished from the rear of the 175RM unit. High pressure does not enter the meter, but is cut down at the meter inlet connection in which the orifice is installed. Various types of connections carrying these orifices are made for the convenience of installation of steel inlet fitlings using standard screwed pipe connections.
