Evaluation of closed-conduit measuring devices for irrigation diversions. Research technical completion report Item Info

A field evaluation of closed conduit flow measuring systems was conducted to determine technically acceptable devices and develop guidelines for measuring irrigation water diversions from surface and ground water sources in the State of Idaho. Recommendations are made for standard installation of acceptable commercially available meters. Types of meters evaluated include propellor, impellor, turbine, differential head, and ultrasonic devices. The nature and quality of the water supply and the hydraulics of the diversion or distribution system greatly influence the acceptability of any flow measuring device and the average water user will not have sufficient technical knowledge for meter selection and placement in his system. Typically, most meters have advertised accuracies of two percent and were shown to have field accuracies within 10 percent.
