Eureka Water Cart Water Meter

This is an inferential-type water meter with serial number 962082, probably made by the Pittsburgh Equitable Meter Company in the 1930s. It has a cast-iron body and a capacity of 240 gallons per minute, and fits a 2” pipe.

Introduced in 1906, the Eureka was described as "a meter of the velocity or inferential type, more commonly designated as a ‘current’ meter. It is especially adapted to the measurement of large and rapidly flowing volumes of water, particularly for supply mains, hydraulic elevators, water motors, railroad standpipes, fire services, street sprinkler carts, or any other class of service requiring a large volume of water without the retardation of the flow, or the perceptible reduction of the effective head or pressure.”
