Calmet Model B-C Water Meter

This oscillating piston water meter with split case and no serial number fit a ¾” pipe. It was made by the Well Machinery & Supply Company in Fort Worth, Texas. It has a cast-iron body and so was probably made during the materials restrictions of World War II.The city of Fort Worth agreed, in 1930, to purchase 8,000 oscillating piston meters from the California Meter Company of Los Angeles. The Well Machinery & Supply Company acquired California Meter soon thereafter, and advertised Calmet water meters as “A Texas Made Product.”
