1、 Mobile Type

This liquid level tester adopts acoustic echo logging, paired with specialized filtering and low-frequency fuzzy automatic recognition algorithms to identify liquid level echoes and collar echoes for accurate liquid depth measurement. It comes with a handheld terminal for on-site parameter display, and may be paired with nitrogen cylinders for wells with zero casing pressure.

2、Fixed Type

Based on acoustic echo logging, dedicated filtering and low-frequency fuzzy recognition algorithms, the unit locates liquid and collar echo signals to calculate liquid depth. All measurement data is remotely transmitted to designated host systems, enabling data access via mobile phones, tablets and PCs at any time. Nitrogen generation units are available as an option for wells with non-pressurized casing strings.
