FLOW RATE MEASURING APPARATUS

摘要

PURPOSE: A flow meter is provided to enable the average flow speed and flow rate at an orifice since a bypass structure is improved so that the orifice is supported using an orifice support member. CONSTITUTION: A flow meter(51) comprises a support member receiving unit, an orifice(63) and an orifice support member. The support member receiving unit is installed on the surface of a space, the main path of a fluid-path block(52). The support member receiving unit is installed on other areas than a fluid-dividing hole comprising area and a collecting hole comprising area. The orifice is inserted into the main path. The orifice support member supports the orifice by the contact with the orifice. The wall of the main path is formed by the inner surface of the orifice support member.
