SH4A-II Echometer

SH4A-II Echometer is a kind of two-channel echometer featuring rational structure, easy operation, lightness and strong depth testing capability. SH4A-II is mainly used to measure the dynamic liquid-level depth or the static liquid-level depth in the pumping wells and casing pressure at well head. Reservoir pressure, downhole pressure and their changes can be calculated according to the height of the liquid column in the casing and its pressure changes to determine the recovery efficiency of the reservoir.Specifications 1.
