超声波液位计（Ultrasonic level meter）

概述

Overview

超声波液位计就是在测量中超声波脉冲由传感器(换能器)发出，声波经液体表面反射后被同一传感器接收或超声波接收，通过压电晶体或磁致伸缩器件转换成电信号，并由声波的发射和接收之间的时间来计算传感器到被测液体表面的距离。由于采用非接触的测量，被测介质几乎不受限制，可广泛用于各种液体和固体物料高度的测量。

An ultrasonic level meter is a measurement in which an ultrasonic pulse is emitted by a sensor (transducer) , and the sound wave is reflected by a liquid surface and then received by the same sensor or ultrasonic wave, by piezoelectric crystals or magnetostrictive devices into electrical signals, and from the acoustic wave emission and reception between the time to calculate the sensor to the measured liquid surface distance. As a result of non-contact measurement, the measured medium is almost unlimited, can be widely used in a variety of liquid and solid materials height measurement.
