Project Background
A customer in Spain was preparing a multi-point water level monitoring project. The project involved several measurement points, including water tanks, underground reservoirs and water management sites where operators needed continuous liquid level data.
Before this upgrade, the customer mainly relied on manual inspection and simple level switches. That approach could provide a basic alarm signal, but it could not show how the water level changed over time. For pump control, storage management and remote monitoring, the project team needed a more stable level measurement solution.
The customer required a batch of sensors that could be installed quickly, connected easily to the control system, and work reliably under long-term submerged conditions.
Monitoring Challenge
Multi-point level monitoring projects are rarely identical at every site. Some tanks are deeper, some wells require longer cable length, and some installation points are located in humid or outdoor environments.
For this shipment to Spain, the key requirements were:
Continuous liquid level measurement
Stable signal output for remote monitoring
Stainless-steel probe body for long-term immersion
Waterproof cable prepared before shipment
Clear wiring for fast field installation
Suitable use in tanks, wells, reservoirs and wastewater collection points
Consistent configuration for multiple monitoring locations
Because the project involved several monitoring points, batch consistency was important. Each transmitter needed to be prepared and checked before shipment so the installation team could reduce wiring and commissioning time on site.
YexSensor Solution
YexSensor prepared the submersible level transmitters according to the customer's project requirements. Each transmitter was assembled with a stainless-steel probe body and waterproof cable, with cable cores reserved for power supply and signal output.
Before delivery, the batch was checked for probe appearance, cable integrity, wiring condition and output readiness. The photo shows the transmitters arranged during the pre-shipment preparation stage.
The submersible level transmitter measures liquid level based on hydrostatic pressure. When the probe is lowered into the liquid, the pressure changes according to the liquid depth. The transmitter converts this pressure signal into a standard output such as 4-20mA or RS485 for connection to a PLC, controller, data logger or IoT gateway.
This solution allowed the customer to use the same level measurement method across different sites while keeping installation simple and maintenance manageable.
Recommended Product Configuration
| Product Type | Recommended Configuration | Application Role |
|---|---|---|
| Submersible Level Transmitter | Stainless-steel hydrostatic level probe | Continuous water level measurement in tanks, wells and reservoirs |
| Signal Output | 4-20mA or RS485 Modbus RTU | Connects to PLC, controller, data logger or remote monitoring system |
| Cable | Waterproof cable, customized length available | Supports different installation depths and field layouts |
| Measuring Range | Selected according to tank or water depth | Matches different level monitoring points in one project |
| Probe Structure | Submersible stainless-steel body | Suitable for long-term use in water and common liquid environments |
The final measuring range, cable length and signal output can be customized according to the actual project site.
Application Scenarios
This type of submersible level transmitter is suitable for water tank level monitoring, well and borehole water level measurement, reservoir level monitoring, wastewater pit and lift station level control, irrigation water management and industrial liquid level monitoring.
Project Value
For the Spanish customer, the value of this batch delivery was not only receiving level transmitters, but receiving a project-ready measurement solution.
By preparing the transmitters with waterproof cables and checking them before shipment, YexSensor helped reduce on-site preparation work. The installation team could connect the sensors directly to the control system and focus on commissioning the monitoring points.
For multi-point water level monitoring projects, using the same type of submersible level transmitter also makes later maintenance easier. Spare parts, wiring methods and signal interfaces can be standardized across different sites.
Conclusion
This shipment to Spain shows how submersible level transmitters can support practical water level monitoring projects where multiple tanks, wells or water management points need continuous measurement.
YexSensor can provide submersible level transmitters with customized measuring range, cable length and output signal, helping project contractors and system integrators build reliable liquid level monitoring systems for different field conditions.
