超聲波液位計工作時，高頻脈沖聲波由換能器（探頭）發(fā)出，遇被測物體（水面）表面被反射，折回的反射回波被同一換能器（探頭）接收，轉(zhuǎn)換成電信號。脈沖發(fā)送和接收之間的時間（聲波的運動時間）與換能器到物體表面的距離成正比，聲波傳輸?shù)木嚯xS與聲速C和傳輸時間T之間的關(guān)系可以用公式表示：S= CⅩT/2
When the ultrasonic level gauge is working, high-frequency pulse sound waves are emitted by the transducer (probe). When encountering the surface of the measured object (water surface), they are reflected, and the reflected echoes are received by the same transducer (probe) and converted into electrical signals. The time between pulse transmission and reception (the motion time of sound waves) is directly proportional to the distance from the transducer to the surface of the object. The relationship between the distance S of sound wave transmission, the sound speed C, and the transmission time T can be expressed by the formula: S=CXT/2
安裝超聲波液位計時必須考慮超聲波液位計的盲區(qū)問題。當液位進入盲區(qū)后，超聲波變送器就無法測量液位了，所以在確定超聲波液位計的量程時，必須留出50公分的余量，安裝時，變送器探頭必須高出液位50公分左右。這樣才能保證對液位的準確監(jiān)測及保證超聲波液位計的安全。
The blind spot issue of the ultrasonic level gauge must be considered when installing it. When the liquid level enters the blind zone, the ultrasonic transmitter cannot measure the liquid level. Therefore, when determining the range of the ultrasonic level gauge, a margin of 50 centimeters must be left. When installing, the transmitter probe must be about 50 centimeters higher than the highest liquid level. This can ensure accurate monitoring of the liquid level and ensure the safety of the ultrasonic level gauge.
在實際使用中，因為安裝時考慮不周，液位計被水淹沒，致使液位計損壞。
In practical use, due to inadequate installation considerations, the liquid level gauge was submerged in water, resulting in complete damage to the gauge.

Low price, small size, light weight, can be used for non-contact level measurement of liquids and bulk solids in industries such as food, chemical, and semiconductor. It can be used for remote level monitoring and pump control
機械安裝時應注意：安裝應垂直于測是物表面，避免用于測量泡沫性質(zhì)物體，避免安裝于距測量物體表面距離小于盲區(qū)距離（盲區(qū)：每臺產(chǎn)品會有一個標準，隨產(chǎn)品得知），應考慮束避開陰擋物質(zhì)不與灌口和容器壁相遇，檢測大塊固體物應調(diào)整探頭方位，減少測量誤差
During mechanical installation, attention should be paid to: the installation should be perpendicular to the surface of the object to be measured to avoid measuring objects with foam properties, and the installation should not be less than the blind area distance from the surface of the object to be measured (blind area: each product will have a standard, which will be known with the product). The beam should be considered to avoid the barrier material and not meet the tank mouth and container wall. When detecting large solids, the probe should be adjusted to reduce the measurement error
