Echometer’s Gas Guns are intended for use with Acoustic Liquid Level Instruments. Assemblies consist of single unit gas gun and microphone. A gun generates a pressure pulse. A microphone converts acoustic pressure pulses into an electrical signal. The gun and microphone are normally supplied together as a unit.
The gun generates a single pressure pulse which travels down the casing annulus and is reflected by collars and the liquid level. The reflected pressure waves deflect the microphone and generate an electrical signal. The electrical signal, is fed to the computerized Well Analyzer which automatically processes the signal or to an amplifier-recorder which amplifies, filters and records the signals on a strip chart. All gas guns are constructed from 316 stainless steel and are suitable for H2S and corrosive service.
