CSLS-1/2C Manhole Leak Detection Sensor
1. CSLS-1 Manhole Leak Detection Sensor (discriminating)：
CSLS-1 manhole leak detection sensor is used to monitor whether liquid exits in the manhole. Two alarm points are set to monitor the liquid level and it can distinguish the liquid is water or fuel. Self-detection function can detect open circuit or short circuit.
Functions:
Two alarm points to detect liquid level
Water alarm
Fuel alarm
Short alarm
Open alarm
Can detect the hydrocarbon, and trigger fuel alarm
Parameters:
Operating temperature range: -40℃~60℃ (fuel); 0℃~60℃ (no freezing water)
Length of sensor cable: 2 m
Size: Length 610 mm; Diameter 55 mm
Alarm points: 30 mm (low level); 285 mm (high level); 4 mm (fuel)
Accuracy: ≤2 mm
Enclosure protection class: IP68

Normally, the monitoring fluid level should keep in the middle of the reservoir which is on the top of the tank. OKet® provides HLS-1D dual-point hydrostatic sensor which can accurately detect fluid-level changes in reservoir in high or low level change. If the brine solution seeps into the tank, lowering the level in the reservoir, the sensor triggers a low-level alarm. If an outer wall leak occurs and groundwater seeps into the tank, a high alarm is activated.Learn More
- SFLS-2DA/2C FRP-Steel Double-wall Tank Leak Detection SensorFor FRP-Steel double-wall tanks, we install a SFLS-2DA/2C double-wall tank leak detection sensor into the lowest point of the interstitial space which is usually on the bottom of the tank. Any leak of the tank occurs, it will trigger an alarm. Usually, the leak of outer wall will lead water from the soil flow into the bottom of the interstitial space, and the leak of inner wall will lead fuel from the inside of the tank flow into the bottom of the interstitial space, then the liquid will be detected by the SFLS-2DA/2C double-wall tank leak detection sensor and trigger an alarm.Learn More
- FSLS-1/2C Tank Containment Sump/monitoring Well Leak Detection SensorFSLS-1/2C is installed in the riser pipe of tank containment sump or a groundwater monitoring well to monitor if there is any liquid in the tank containment sump or fuel on the underground water in the well in real time. Three alarm points are set to detect the liquid is fuel or water. Self-detection function can detect open circuit or short circuit.Learn More
