Description

Technical Field

[0001] The utility model provides an ultrasonic liquid level meter, belongs to the technical field of ultrasonic liquid level meter equipment, and particularly relates to a corrosion-resistant ultrasonic liquid level meter. Background Art

[0002] Ultrasonic level meter is an instrument that uses ultrasonic signals to measure liquid level. Its working principle is that the ultrasonic transmitter emits ultrasonic pulses to the liquid surface, and the ultrasonic wave is received by the receiver on the same device after being reflected on the liquid surface. The liquid level is determined by calculating the product of the ultrasonic round trip time and the known sound speed. This technology is widely used in various liquid storage and processing facilities, such as water treatment plants, chemical plants, food processing plants and petrochemical equipment.

[0003] Most of the existing ultrasonic level meters have a mounting hole opened on the storage tank, and the device is installed above the storage tank with the help of the mounting bolts on the level meter for detection. However, when this structure monitors highly corrosive liquids, there is a lot of corrosive water vapor in the storage tank, which may gather into water droplets, which will not only damage the equipment but also affect the accuracy of the ultrasonic converter. At the same time, if the liquid inside the tank shakes during transportation, it may splash onto the converter and damage the equipment. Utility Model Content

[0025] In this embodiment, a protective cover 2 is provided on the outside of the converter 11 to protect the safety of the converter 11 and prevent splashing of acidic liquid. At the same time, the conical shape allows the protective cover 2 to be used for drainage after water vapor condenses, and the sealing plate 21 can prevent internal gas from leaking.

[0026] like Figure 2 and Figure 3 As shown, a thread 23 is provided on the outer wall of the sealing plate 21, and the shapes of the sealing plate 21 and the blocking plate 22 adapt to the shape of the tank body of the liquid storage tank. A PTFE protective shell 14 is provided on one end of the converter 11 placed inside the protective cover 2, and the interior of the protective cover 2 is provided with an annular inclined surface 24 which is sleeved on the outside of the PTFE protective shell 14, and the inclined surface 24 and the interior of the protective cover 2 are provided with corresponding grooves 25.

[0027] In this embodiment, the PTFE protective shell 14 can effectively prevent the erosion of corrosive liquids while avoiding affecting the transmission and reception of ultrasonic waves; the inclined surface 24 and the groove 25 on the protective cover 2 can be used to assist the condensation of water vapor, so that the liquid slides down along the protective cover 2 to avoid staying on the converter 11 for a long time.

[0028] When in use, fix the level meter body 1 to the corresponding position of the liquid storage tank to ensure that the installation position of the level meter can effectively measure the liquid level change; connect the converter 11 to the bottom of the level meter body 1, and ensure that the converter 11 is covered with a conical protective cover 2, and use the locking nut 12 to firmly connect the converter 11 and the protective cover 2 to the level meter body 1; install the sealing plate 21 between the level meter body 1 and the blocking plate 22, and fix it to the blocking plate 22 by using the thread 23 on its outer wall to adapt to the tank shape of the liquid storage tank; install the PTFE protective shell 14 at one end inside the protective cover 2 to protect the converter 11 from corrosion. To prevent the corrosion of corrosive liquids, ensure that the inside of the protective cover 2 is provided with an annular slope 24 which is sleeved on the outside of the PTFE protective shell 14, and the slope 24 matches the groove 25 inside the protective cover 2; open the liquid level meter body 1, check the equipment status and liquid level readings through the digital display screen 13, regularly check the integrity of the protective cover 2 and the PTFE protective shell 14 to ensure that there is no corrosion or damage, clean the inside of the protective cover 2, especially the slope 24 and the groove 25, to ensure that there is no blockage or water accumulation, maintain effective condensation and drainage of water vapor, continuously monitor the liquid level data through the digital display screen 13, and use the built-in data processing function to analyze the trend of liquid level changes. The design of this level meter allows it to stably measure the liquid level in a corrosive environment, while reducing maintenance requirements and enhancing the durability of the equipment through a specific structure. During use, it is key to ensure the correct installation and regular maintenance of all components.
