Checking the water depth of a reservoir may be required during routine inspection, maintenance, engineering assessment or preliminary site investigation.
Traditional methods such as a measuring pole, weighted rope or levelling staff can work for shallow and easily accessible locations. However, these methods become less practical when the water is deeper or the required measurement point is away from the reservoir edge.
The HONDEX PS-7FL Portable Depth Sounder with Float provides a portable electronic solution for spot water-depth measurement.
Portable Reservoir Depth Measurement
The HONDEX PS-7FL is designed for convenient field measurement and offers a depth measurement range of approximately:
0.6 m to 80 m
The instrument uses a 200 kHz ultrasonic sensor to determine the distance from the water surface to the bottom.
This makes the PS-7FL suitable for applications where engineers or maintenance personnel need a quick indication of water depth without using a long physical measuring pole.
Where Can Reservoir Depth Measurement Be Useful?
Potential applications in Malaysia include:
Water reservoir inspection
Raw water storage facilities
Industrial water reservoirs
Retention ponds
Irrigation reservoirs
Construction water bodies
Drainage infrastructure
Environmental field inspection
Civil engineering assessment
The PS-7FL is particularly suited to portable spot checking rather than complex hydrographic mapping.
Why Is the Float Important?
One of the distinguishing features of the HONDEX PS-7FL is its float sensor arrangement.
The transducer can be positioned on the water surface using the float, while the main instrument remains with the operator.
The supplied configuration uses a 10 m transducer cable, providing additional flexibility when the required measurement position is away from the immediate edge.
This can be useful around reservoir banks where direct access to the desired measurement point may be inconvenient.
HONDEX PS-7FL vs Measuring Rope
A weighted measuring rope is inexpensive and can be useful for basic depth checks.
However, the operator must physically lower the weight until it reaches the bottom. Depending on the site, this can be inconvenient and readings can be affected by factors such as current, positioning and determining exactly when the weight reaches the bottom.
The PS-7FL takes a different approach by using ultrasonic depth measurement.
For teams that perform water-depth checks regularly, an electronic portable depth sounder can therefore be a useful addition to their field equipment.
HONDEX PS-7FL vs 5m Levelling Staff
A 5 metre levelling staff is useful for many surveying and construction applications, including accessible shallow-water measurements.
But what happens when the water is:
6 metres deep?
10 metres deep?
20 metres deep?
A normal 5 m staff is no longer suitable for directly reaching the bottom.
With its approximately 0.680 m measurement capability, the HONDEX PS-7FL covers a substantially greater depth range.
This is why the two instruments should be viewed as tools for different field conditions rather than direct replacements for each other.
Can PS-7FL Be Used to Check Reservoir Sedimentation?
Water-depth measurements taken at selected points may help identify locations where the measured depth appears to have changed and where sedimentation may warrant further investigation.
However, it is important to distinguish a portable spot depth sounder from a complete bathymetric survey system.
If a project requires:
Detailed reservoir bottom mapping
Continuous depth profiles
GNSS coordinates
Volume calculations
Sediment volume modelling
Engineering-grade bathymetric survey deliverables
then professional hydrographic or bathymetric surveying equipment and appropriate survey methodology may be required.
For straightforward spot depth checking, the HONDEX PS-7FL provides a much simpler portable option.
Who Should Consider the HONDEX PS-7FL?
The PS-7FL may be useful for:
Civil contractors
Surveying teams
Engineering consultants
Facility maintenance teams
Water infrastructure operators
Environmental field teams
Drainage contractors
Reservoir maintenance personnel
For organizations that only need occasional water-depth checks, portability and ease of deployment can be more important than operating a complete hydrographic survey system.
