GT Groundwater Detectors, Pipeline Robots & GPR

Choose the stated investigation range from the planned survey depth and local geology: GT150A for shallower work, GT300A for medium-depth surveys and GT500A for deeper screening. A stated range is not a guarantee of water or drilling depth; confirm targets with geology, repeatable profiles and drilling or pumping tests.

PQ125A is focused on indoor concealed pipes, PQ125B on outdoor buried pipes, PQ125C combines indoor and outdoor sensors, PQ125D adds a broader four-sensor configuration, and PQ125E adds tracer-gas capability. Final selection depends on pipe material, diameter, burial depth, route length and background noise.

No. Electrical or natural-field surveys identify subsurface anomalies that may be consistent with water-bearing structures; they do not directly guarantee flow rate, salinity or drinking-water quality. Verify with local geology, borehole records, drilling, pumping tests and laboratory water analysis.

Provide the pipe material, diameter, burial or concealment depth, route length, indoor or outdoor environment, operating pressure, surface type and site noise. These details determine whether acoustic, multi-sensor, pipeline-locating or tracer-gas methods are appropriate.

Ground-penetrating radar can help map buried utilities and identify disturbed ground, voids or moisture-related contrasts, but it usually does not prove that a water leak is present. Use GPR as route and context evidence, then confirm the candidate section with pressure or flow checks, acoustic listening, correlation, tracer gas or excavation.

PQWT-PQ325E is designed for DN250 and larger sewer or drainage pipes. Confirm the minimum and maximum internal diameter, access-opening size, inspection distance, bends, steps, water, silt and recording requirements before the crawler and wheel package is quoted.
