2. Product principle：
Under the functional control of the combined unit and electronic components, the ultrasonic level gauge or liquid level gauge emits sound waves above 20KHz to the measured object, and the echoes partially reflected on the surface of the object are received by the probe and converted into sound waves. For electrical signals, the time from ultrasonic transmission to re-reception is proportional to the distance. The level is calculated by detecting the time and calculating the measured distance from the known speed of sound.
3. Protection level:
How to ensure that the installation meets the IP68 requirements as shown in the picture: Please make sure that the sealing head is not damaged. please ensure this
The instrument cable is not damaged. Make sure that the cables used comply with the electrical connection regulations. in progress
The instrument fully meets the requirements of protection class IP68, please ensure the waterproofness of the cable sealing head.
※Before entering the electrical connection, bend the cable down to ensure that water cannot flow into the housing, marked ①
※Please tighten the cable gland marked ②
※Please use a blind plug to block the unused electrical interface, marked as ③
4. Installation requirements：
For vaulted storage tanks, it is best not to install the Ultrasonic level gauge at the center of the tank roof, but at 1/2 or 2/3 of the radius of the tank roof (under the premise of meeting a certain distance from the tank wall). The domed tank top acts like a convex lens to the ultrasonic pulse, and if the probe is mounted at the focal point of the convex lens, it will pick up all false echoes. Therefore, it should be avoided to install the sensor probe in the center of the vaulted tank roof.
