Meters, Steam Builders Iron Foundry 23 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 nearby or 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. S&unt Steam' Meter, Type, &-S- - THE SHUNT METER Distinctly fills the need for a low priced, practical, mechanical, meter easily installed and accurate over, a wide range. Regularly used by many District Heating Com panies for measuring steam sold; also ordered and re ordered by leading industrial plants to meter steam or air furnished tenants, departments, and 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 tampering fan on the vertical turbine shaft, at the bottom end of which is a magnetic drive-to_the totalizer dials. The meter is installed as a unit in 2, 3 and 4-in. lines; for larger capacities the installation is made in a by-pass around an orifice in the main line.
