A laser oil tank level meter
Measurement principle
Wuhan Xinfeng Optoelectronics independently developed a new type of laser oil tank level meter
Fiber optic liquid The level gauge is a new type of liquid level gauge developed to meet the needs of oil depot liquid level measurement. It uses the principle of laser ranging to couple a beam of laser into the optical fiber and guide it to the top of the oil tank through a special collimation device. The controller It is placed in the central control room with the light source. The measurement site is completely uncharged and the entire system is intrinsically safe.

Fiber optic liquid level gauge system structure and working principle
Fiber optic liquid level sensor probe
The fiber optic sensor probe is composed of a high-precision optical coupler and an optical path adjustment device, which mainly completes the optical signal Transceiver and collection of liquid level data, the collected liquid level value is sent to the controller through optical fiber. This probe is installed on the top of the oil tank. It uses optical signals without any electrical signals and is intrinsically safe and explosion-proof.
Sensor control terminal
The controller is composed of a power fiber optic liquid level sensing module conversion circuit board and a display screen. It is responsible for modulating and demodulating the optical signal. Bit signals are replaced by electrical signals. The controller has functions such as system initialization, historical data query channel setting, time setting, and restoration of factory settings. It has output and modules. Through these communication modules, the liquid level information can be transmitted to the industrial control system computer and monitor to realize liquid level data display.
