FLOW METER WITH CANTILEVERED-MOUNTED TURBINE

摘要

A miniaturized turbine meter is disclosed. While the size of the turbine meter is small, it performs all the functions of prior turbine meters and has a large rangeability over a very large range of pressure. The turbine meter includes a body (13) which is bilateral and sometimes symmetrical, permitting the turbine meter to be installed in either orientation in a flow line. A first diffuser (15) is included with the turbine meter which maintains the rotor of the turbine meter in position by having a cantilevered shaft extending from the diffuser. A second diffuser or shroud is placed over the end of the cantilevered shaft farthest from the first diffuser and is spaced so as to avoid forcing engagement with the end of the cantilevered shaft, whereby the clearances of the two diffusers are non-critical and misalignment is avoided.
