Insulation Underground Steam Construction Co. 75 Pitts Street, Boston, Mass. PRODUCTS--Underground Steam Conduits. Engineering and Contracting of Steam Line Installations. USCCO PRE-CAST CONCRETE CONDUIT This unit marks a long step forward in the economics and mechanics of laying under ground steam lines. Its Outstanding Features Are: Strength resulting from flat reinforced bell; from the longitudinal joints, and from the fact its sections are 4 feet long, reducing- the usual number of joints necessary. Shape which allows 12 per cent greater inside capacity than circular conduit of like diameter. This permits larger pipes in a given size conduit and more room for. drainage, pipe supports and rolls. Ease of Installation resulting from the fact that all top and bottom halves mate. Bottoms may be laid for any distance, the piping installed and then the tops brought up and laid. This speeds up the work and protects idle halves from damage. They can be stored away from the job. Materials are high strength cement with suitable aggregate, amply reinforced with wire mesh. > t'* --sw- ."*r V- Pipe Supports are of cast-iron and quickly installed. They may be placed anywhere in the conduit. The weight of the pipe holds them in place. * Joints may be of any standard accepted brand of jointing compound or they may be of standard Portland cement mortar. 718 Meiers, Steam Builders Iron Foundry 9 Codding Street Providence, R. I. Representatives In Principal Cities The VENTURI METER for water supply, boiler feed and other main pipe lines. The CHRONOFLO ELECTRIC FLUID METER for long distance transmission of flow rates, quantities, pressures, temperatures, etc. The SHUNT METER for steam, air and gas. THE CHRONOFLO ELECTRIC FLUID METER "From hundreds of feet to hundreds of miles" The Chronoflo has introduced new features to the field of metering. Four common electric units are utilized: the synchronous motor; the mercury switch; the magnetic relay; the magnetic clutch. Electric impulses of variable time intervals proportional to rates or positions are transmitted by the primary unit to the receiver gauge. Regular A.C. current is used and accuracy is not affected by voltage variation. Suitable for in tramural or long distance transmission over regular telephone channels. Shunt Steam Meter, Type KJ5- THE SHUNT METER Distinctly filling the need for a low priced, practical, mechanical, meter easily installed and accurate over a wide range. For measuring steam sold or in checking distribu tion of steam (also air or gas) to buildings, departments dr processes. The illustration shows the complete meter. Installation consists simply of'bolting to flanges in the flow line; no connecting pipe or electric wiring. A portion of the entering steam is deflected by an orifice through nozzles against the blades of a turbine located in the upper or shunt passageway. The speed of the turbine is kept low by a damping fan on the vertical turbine shaft, at the bottom end of which is a magnetic drive to the totalizer dials. The meter ^installed as a unit in 2, 3 and 4-inch lines; for larger capacities the installation is made in a by-pass around an orifice in the main line. Steam Pressure Lbs. per Sq. In.
