101 Impeller Flowmeter

Flowmeter is an acquisition device in robust case for bi-directional measurement of the rotation speed of a turbine wheel (impeller), related to flow of fluid inside the well. Data are are digitalized and send by digital communications to surface. This tool is designed for stationary measurements only.
