Modification in gate valve using flexible membrane pipe for flow measurement

open access: yesSN Applied Sciences, 2021
A gate valve is used to regulate discharge in pipelines. It is rotated by a wheel that is attached to a circular disc (i.e. gate) at the top of a stem. Each revolution of the wheel creates a particular linear disc movement that changes the flow zone. The
