MULTI-POINT DIFFERENTIAL PRESSURE FLOW METER

摘要

The present invention relates to a flow meter and a system for measuring the flow rate of a pipe with the flow meter. The flow meter comprises: a first body having multiple total pressure holes; a second body overlapped with the first body and having multiple static pressure holes; and a differential pressure sensor connected to the first and second bodies to calculate the differential pressure between the pressures measured through the total pressure holes and the static pressure holes. In order that the differential pressure is measured as a mean value inside a pipe, the multiple total pressure holes are arranged along the circumferential direction of the first body and are connected by the first body to collect fluid entered through the total pressure holes at one point. Accordingly, the flow rate measuring device can conveniently measure the flow rate with less pressure loss. [Reference numerals] (130) Differential pressure sensor; (20) Flow rate calculator
