FSLS-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.

It is suitable for the vacuum negative pressure leakage measurement method of lining method. By detecting the pressure of the middle layer of the double layer tank, the pressure state of the middle layer of the double layer tank of the lining method can be monitored in real time to judge the leakage of the oil tank.

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/2C double-wall pipeline leak sensor which connects the lowest point of the interstial space of the double-wall pipeline with a fuel collecting tube .

CSLS-1/2C 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.

DPLS-1/2C dispenser pan leak detection sensor is installed in the dispenser pan to monitor if there is any liquid exiting in real time. Any fuel/water presented in the bottom of dispenser pan will be tested and alarmed. 

SIoT-100 is an Internet of Things intelligent display terminal independently developed and produced by OKet, which is composed of a controller and a touch screen display. At the same time, it can form a mature and complete intelligent control system of the Internet of Things with OKet PLS type liquid level detector and a variety of leak detection sensors, as well as fuel gun equipment, oil and gas recovery online monitoring equipment, camera equipment and so on.

Based on the standard metal gauge, temperature and liquid level detection sensors are added to collect real-time data and automatically calculate the accuracy of the oil gun.

The mobile APP is connected to the device via Bluetooth and can obtain each test data from the device. After multiple tests, a verification report can be generated. The content of the verification report includes time, gas station name, nozzle number and temperature, altitude, and accuracy data.

The underground tank calibration of OKet adopts the capacity comparison method, which includes two data acquisition methods.

The gas station unloading process controller is a process control device specially designed by OKet for the standard unloading process of gas stations.

The Over Fill Protective Valve is composed of clamping swing valve, explosion-proof solenoid valve, pull rod lock and manual button.

Based on digital and networked video surveillance, the AI intelligent video analysis system adopts AI intelligent behavior analysis technology to realize automatic identification of hidden dangers, second-level early warning, intelligent control, Real-time forensics.
