FLOW MEASUREMENT SYSTEM Russian patent published in 2023 - IPC G01F1/66 

FIELD: flow measurement system.

SUBSTANCE: present invention is designed for measuring the flow rate of a fluid in a high pressure pipeline. The flow measurement system is comprised of a measuring body that has an inlet flange, an outlet flange and a fluid channel, the fluid channel having a channel axis, an ultrasonic measuring device built into the measuring body, and a flow conditioner located upstream of the ultrasonic measuring device in the fluid channel. An arrangement of holes for fastening means is provided on the output flange, wherein the axially extending outlet region of the fastening of the measuring body is formed by the length of the holes. The ultrasonic measuring device has at least one reflection measurement path, which is measured by the first ultrasonic transducer, the reflector and the second ultrasonic transducer and which passes in the measurement plane through the fluid channel so that the second ultrasonic transducer is located downstream of the first ultrasonic transducer. The second ultrasonic transducer, located downstream, is located in the outlet area of the attachment or protrudes into it.

EFFECT: providing a relatively high measurement accuracy and a large tolerance with respect to disturbed flow profiles with a relatively short installation length of the device.
