Borehole flowmeters are downhole tools that:measure axial flow ina wel
l or borehole. Desirable flowmeter characteristics include low detecti
on limit, a wide range of operation, accuracy, durability: reliable pe
rformance, and a Small diameter and-length. The recently developed ele
ctromagnetic (EM) flowmeter has these traits. The first portion of: th
is paper presents the EM flowmeter design, provides laboratory calibra
tion data, and compares the performance characteristics of EM flowmete
rs to those of impeller and thermal-pulse flowmeters. The second porti
on of the paper discusses applications of the EM flowmeter.
