Canal & Waterway Depth Measurement Malaysia – HONDEX PS-7FL Portable Depth Sounder
Canal & Waterway Depth Measurement Malaysia – HONDEX PS-7FL Portable Depth Sounder
CONTENT
Measuring the depth of a canal, drainage channel or waterway can be required during surveying, civil engineering, infrastructure maintenance and drainage inspection.
For shallow channels, a measuring pole or levelling staff may be sufficient. However, when the water becomes deeper or the required measurement location cannot conveniently be reached, direct physical measurement becomes more difficult.
The HONDEX PS-7FL Portable Depth Sounder with Float provides a practical option for portable spot water-depth measurement in suitable canal and waterway applications.
Why Measure Canal or Waterway Depth?
Water-depth measurements may be useful during:
-
Canal inspection
-
Drainage survey
-
Waterway maintenance
-
Flood mitigation projects
-
Civil engineering site investigation
-
Infrastructure inspection
-
Irrigation channel assessment
-
Construction projects
-
Environmental field surveys
For routine inspection, the requirement may simply be to obtain several depth readings rather than perform a complete underwater survey.
HONDEX PS-7FL Measurement Range
The HONDEX PS-7FL provides an approximate water-depth measurement range of:
0.6 m to 80 m
Operating frequency:
200 kHz
The transducer sends an acoustic signal through the water and determines the distance to the acoustically detected bottom.
Unlike a conventional measuring pole, the instrument does not need to physically reach the canal or waterway bed.
Why Is the Float Useful?
The PS-7FL includes a float configuration with a 10 m transducer cable.
Where site conditions permit, the transducer can be positioned on the water surface away from the immediate edge.
This can provide additional flexibility when working around:
Concrete canals
Large drainage channels
Irrigation waterways
Flood-control channels
Industrial drainage systems
River-connected waterways
PS-7FL vs 5m Levelling Staff
A 5m levelling staff remains an economical solution when the water is shallow and the bottom is accessible.
For example:
1–2 m water depth
A staff may be the simplest solution.
3–4 m water depth
A staff may still be suitable depending on access.
More than 5 m
A conventional 5m staff can no longer directly reach the bottom.
The PS-7FL's approximately 0.6–80 m measurement range provides significantly greater depth capability under suitable conditions.
Can PS-7FL Measure a Large Concrete Drain?
For suitable water-filled drainage channels, the PS-7FL can be considered for spot water-depth measurement if the transducer can be positioned correctly.
However, site conditions matter.
Users should consider:
Water depth
Flow velocity
Debris
Channel geometry
Sensor positioning
Access
Safety
Fast-moving water or difficult structures may require a different measurement approach.
Can It Measure Canal Siltation?
The PS-7FL measures water depth to an acoustically detected bottom.
Repeated depth measurements at known locations may help identify areas that appear to be becoming shallower.
However, a shallower reading does not automatically prove that a specific thickness of sediment has accumulated.
Changes in water level must also be considered.
For detailed siltation studies, a professional survey or additional sediment investigation may be required.
Can PS-7FL Measure Water Flow?
No.
Water depth and flow are separate parameters.
The HONDEX PS-7FL measures depth.
If the project requires:
Flow velocity
Discharge
Current speed
Flow rate
then appropriate flow-measurement equipment is required.
For drainage and hydraulic studies, both depth and flow information may be important, but they are obtained using different measurement methods.
Useful for Flood Mitigation Projects
Drainage and flood-control projects may involve:
Rivers
Canals
Retention ponds
Stormwater channels
Large drains
Reservoirs
A portable depth sounder can provide quick spot measurements during preliminary field inspection.
If detailed channel profiles or hydraulic modelling data are required, additional surveying and engineering work will be necessary.
Combine PS-7FL with Surveying Equipment
For more complete canal or waterway fieldwork:
HONDEX PS-7FL
→ Water depth.
Auto Level / Digital Level
→ Elevations and level differences.
Total Station
→ Channel geometry, position and topography.
GNSS / RTK
→ Coordinate positioning.
This combination can be particularly useful for civil engineering and surveying teams.
Spot Measurement vs Complete Canal Survey
Before selecting equipment, define the required output.
If the requirement is:
“We need to know the water depth at several locations.”
the HONDEX PS-7FL may be suitable.
If the requirement is:
“We need the complete canal-bed profile with coordinates and engineering survey data.”
then a more comprehensive surveying or hydrographic approach may be required.
Who Should Consider HONDEX PS-7FL?
Potential users include:
Drainage contractors
Civil engineering consultants
Surveyors
Infrastructure maintenance companies
Irrigation contractors
Environmental consultants
Construction companies
Industrial facility teams
For companies that occasionally need to measure water depth, a portable instrument can be considerably simpler than maintaining a complete hydrographic survey setup.
