DLLS-2DA/2C Double-wall Pipeline Leak Detection Sensor

1. DLLS-2DA Double-wall Pipeline Leak Detection Sensor

The double-wall pipeline is sloped during the installation to ensure its contents will drain back into the storage tank . So we could install a DLLS-2DA double-wall pipeline leak sensor which connects the lowest point of the interstial space of the double-wall pipeline with a fuel collecting tube . If any leak happened in the pipe , the liquid in the interstitial space will flow to the lowest point of the pipe and then go through the fuel collecting pipe to the container of the DLLS-2DA double-wall pipe leak sensor . When the sensor detects liquid, then an alarm will be activated .

Functions:

• Real-time monitoring whether liquid exists in the interstitial of the double-wall pipeline. Once the fuel was detected by the sensor, it will trigger an alarm

• Water alarm

• Fuel alarm

• Short circuit alarm

• Open circuit alarm

• Can detect the hydrocarbon, and trigger fuel alarm

Parameters:

• Operating temperature range: -40℃~60℃ (fuel); 0℃~60℃ (no freezing water)

• Alarm points: 4 mm (fuel); 55 ml (liquid)

• Size: Length 103.5 mm; Diameter 63.5 mm

• Enclosure protection class: IP68

• Length of sensor cable: 2 m

• Accuracy: ≤2 mm
