Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge structure technology, and in particular to a liquid level gauge capable of data self-testing. Background Technology

[0002] A level gauge is a device used to measure liquid level. A radar level gauge is a type of level gauge. It is a measuring instrument based on the time-of-flight principle. Radar waves travel at the speed of light, and the travel time can be converted into a level signal by electronic components. The probe emits high-frequency pulses that propagate in space at the speed of light. When the pulses encounter the material surface, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal.

[0003] Existing level gauges cannot perform data self-checks during use, which prevents timely detection of malfunctions and affects their usability. Utility Model Content

[0004] The purpose of this invention is to provide a level gauge that can perform data self-checks when a malfunction occurs during operation, thus not affecting the working effect of the level gauge.

[0010] Furthermore, a connecting seat is provided at one end of the protective cover, and one end of the connecting seat is rotatably connected to the mounting seat.

[0011] By adopting the above technical solution, the protective cover can be easily rotated and opened via a rotating connection.

[0012] Furthermore, the support base is provided with friction grooves on its exterior, and there are several friction grooves arranged sequentially inside the outer wall of the support base.

[0013] By adopting the above technical solution, the level gauge can be easily rotated and installed using the friction groove.

[0014] Furthermore, the docking flange and the support base are an integral structure, and the docking flange is provided with four fixing screw holes inside, which are symmetrical about the vertical center line of the docking flange.

[0015] By adopting the above technical solution, the level gauge can be easily installed through the fixing screw holes provided on the docking flange.

[0016] Furthermore, the protective device is welded to the docking flange, and threaded fixing seats are provided around the outer wall of the upper end of the protective device.

The electronic component also has mounting feet on both sides of its lower end, and the mounting feet are fixedly connected to the lower protective shell by mounting screws. The miniature audible and visual alarm has a fixing end at its lower end, and the fixing end is fixedly connected to the lower protective shell by fixing screws.

[0019] By adopting the above technical solution, electronic component one, electronic component two, and the miniature audible and visual alarm can be easily installed and fixed. The miniature audible and visual alarm can promptly sound an alarm when data errors occur.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model can monitor the liquid level by installing a detection probe one, and transmit the monitored data to electronic component one, thereby realizing real-time monitoring of the liquid level. Then, the liquid level is detected periodically by a detection probe two, and the detected data is transmitted to electronic component two. Electronic component one and electronic component two can observe whether the real-time monitored data and the periodically detected data value are close. When the difference between the two data values ​​is too large, an alarm is triggered by the installed miniature audible and visual alarm. This allows staff to promptly observe and handle abnormal liquid levels.

[0022] 2. The installed docking flange of this utility model can facilitate the installation and fixation of the level gauge. The installed protective device can protect the first and second detection probes, and the threaded fixing seat of the protective device can further fix the level gauge in place.
