What are the advantages of ultrasonic external level switches? External level switches feature the benefits of no need for welding or tank cleaning, simple installation and maintenance, high reliability, and high precision. Below are the advantages of these externally mounted ultrasonic level switches. http://bbs.elecfans.com/data/attachment/forum/202005/27/173043rehpyxfvpbcp8zm5.png.thumb.jpg First, in terms of the measurement method: external ultrasonic level switches operate differently from other types of level gauges (for which it is necessary to make holes in the container in order to measure the liquid level inside it). Magnetic flap level gauges, on the other hand, do not require any holes to be made in the container; they utilize the principle of micro-vibration analysis to continuously determine the exact height of the liquid surface from outside the container. Secondly, in terms of safety performance and cost control: the external ultrasonic level switch is a true non-contact measuring instrument. Its sensors are installed at the bottom and sides of the container; it enables fast, reliable, and high-precision measurement of the container’s volume. It is easy to install without damaging the container, and there is no need to stop the equipment during installation. The external ultrasonic level switch has no moving parts, which means it requires almost no maintenance. http://bbs.elecfans.com/data/attachment/forum/202005/27/173110qvlrjnjorzz1rwoo.jpg.thumb.jpg Therefore, external ultrasonic level switches have their unique advantages: no holes need to be made in the tank wall to install the sensor, and such sensors neither come into contact with the liquid medium inside the container nor with the gaseous medium there. It effectively solves the world-class technical challenge of measuring liquid levels under extremely harsh and demanding conditions such as strong corrosion, high toxicity, high pressure, flammability and explosiveness, high purity, and the absence of microbial contamination. Because the external level gauge does not come into contact with the liquid inside the container at all. The above is an analysis of the advantages of external-mounted ultrasonic level switches. It is known that these switches are extremely safe and reliable in use, require very simple installation and maintenance, and represent environmentally friendly measuring instruments.
