Abstract

Abstract A flowmeter of the area-type having a connecting pipe member for connecting the meter to a main line through which a fluid to be measured flows. The connecting pipe member is formed with an orifice disc or plate so that a bypassing flow of the fluid is produced by a pressure differential in the fluid flow between the upstream side and the downstream side of the orifice, which flow takes place by way of bypassing inlet and outlet ports provided respectively on the upstream and downstream sides of said orifice and within a meter-mounting collar formed on the connecting pipe. The inlet and outlet ports are operatively connected with a flowmeter having a mounting base cooperable with said mounting collar, and provided with separate feed and return passageways in the base, and with a feed-receiving float line and a return line adjacent thereto, so that a common communication pipe line thereof has one end which is connected with either the inlet or outlet passageway, and the separate passageways in said mounting base are so disposed so that irrespective of whether the other end of the communication-connecting pipe is connectably inserted within either of said inlet or outlet port of said connecting pipe member then the bypassing flow of the fluid is introduced into a tapered line having a built-in float which is adapted to be moved by the bypassing flow of fluid into a position indicating the rate of flow of the fluid through the main line, whereupon said bypassing fluid is then passed through the return line of the meter to reenter the main line.
