Vostok-AL series acoustic mole

Designed to control the movement and passage of cleaning and diagnostic equipment through pipelines at arbitrary points of the pipeline route from the soil surface above the pipeline, as well as on valves, taps, plungers, open sections of the pipeline.


It consists of an electronic control unit, a headset, an extension cable with a geophone, a magnetic holder, a power cord from the vehicle's on-board network, a stowage case.

Operating procedure

The geophone is installed at the control (listening) point on the ground above the pipeline using a pin or on the valve body, valve, pipe body using a magnetic holder.

Control of the passage of the projectile is carried out by ear through a headphone and / or visually by a pointer (LED) indicator. The speed of the projectile is not limited.

This device is protected by patent No. 2137977
