Valve
The valve is designed to create the acoustic impact for the wells with overpressure.
Acoustic signal generators (UGAS / Gas Guns)
The units are designed to create a sound wave in wells with or without pressure. Includes a rubber crimped pump as standard for measuring levels up to 1000 meters. Additional equipment may include a hand pump, a compressor or a cylinder with compressed air, which allows you to measure levels up to 4500-6000 meters.
