Q83: Water measuring device used for determining discharge from a piped... - Water Management - ICAR AIEEA PG Agronomy 14 July 2023 (Shift 1) Paper | Agrigyan

Discharge measurement in pressurized pipe networks:

• In closed conduit piped irrigation systems (such as sprinkler and drip networks), water flows under positive hydrostatic pressure.
• Discharge is measured using in-line flow meters (propeller meters, turbine meters, or electromagnetic/ultrasonic meters).
• Weirs, V-notches, and Parshall flumes are used exclusively in open-channel gravity flow systems.
