and the later data processing can be carried
out to facilitate the submission of results.
PRODUCT INTRODUCTION
LSDLD-20 professional dyke pipe surge leakage detector is a new instrument designed and manufactured according
to the basic principle of "swab field method". High precision, high accuracy and rapid detection of river, reservoir dam
piping leakage inlet, leakage channel, is earth dam, stone dam or concrete dam and other dam itself and foundation
piping leakage detection.
LSDLD-20 professional dyke surge leakage detector is composed of transmitter, receiver and sensor. Based on the
theory of "swab field method", it applies "pseudo-random" current signal sending and receiving technology, near field
source strengthening anomaly technology, high resolution and rapid current density field detection technology,
current density field multi-component detection technology, etc. Embedded intelligent industrial computer as the
main platform, human-computer interaction friendly, can connect RTK, depth sounder, to achieve high precision data
acquisition and positioning.
In the harsh environment of flood season, it can quickly and accurately determine the specific location of piping
leakage, so that people can take effective treatment measures in time, significantly reduce the investment of flood
fighting and rescue, and greatly reduce the loss of people's lives and property. In the non-flood season, the instrument
can be used for river, reservoir dam maintenance and management projects, to protect water resources. It can be used
to detect all kinds of dam body and foundation such as earth dam, stone dam or concrete dam.

APPLICATION CASE
The dike piping leakage detector was used for field
operation demonstration. The actual field work
time was very short, including construction wiring
and water surface measurement, before and after
less than 3 hours, quickly and accurately completed
the task, which has a high precision and accuracy
for the discovery of piping leakage, and provides a
scientific basis for the flood control work.
