An oil flow baffle is rotatably connected to the inside of the mounting bracket through a rotating shaft. An angle sensor for real-time feedback of the rotation angle of the rotating shaft of the oil flow baffle is installed on the outside of the mounting bracket.
[0006] Further, a signal transfer module is arranged on the inner wall of the housing.
[0007] Further, the angle sensor is located below the liquid level sensor.
[0008] Further, the liquid level sensor is located at the front end of the reed switch.
[0009] Further, both the liquid level sensor and the angle sensor are provided with DC power supply through a power supply module.
[0010] Further, a pipeline body is assembled at the bottom of the housing through a mounting bracket.
[0011] Different from the prior art, the beneficial effect of this application is as follows:

A reed switch 700 is installed at the bottom of the housing 100. A liquid level sensor 400 is located at the front end of the reed switch 700. A liquid level sensor 400 is installed on the outside of the mounting bracket 200. A flow baffle 600 is rotatably connected to the inside of the mounting bracket 200 by a rotating shaft.

When using the pipeline body 800, the liquid level sensor 400 will transmit the real-time data of the liquid level to the external receiving end through the signal transfer module; at the heavy gas flow baffle 600, an angle sensor 500 is added. When there is liquid flow, under the push of the oil flow, the angle of the flow baffle 600 will change. Through the angle sensor 500, the real-time data of the angle can be transmitted to the external receiving end through the signal transfer module. In this way, on the premise of retaining the traditional mechanical and physical protection principle, intelligent detection components are added, and the light gas volume and the real-time flow rate of the heavy gas liquid can be remotely and real-time displayed, making the device easier to use.

At this time, both the liquid level sensor 400 and the angle sensor 500 on the mounting bracket 200 are located inside the relay. And a liquid level sensor 400 is added at the light gas alarm contact reed switch 700. When using the pipeline body 800, the liquid level sensor 400 will transmit the real-time data of the liquid level to the external receiving end through the signal transfer module; at the heavy gas flow baffle 600, an angle sensor 500 is added.
