在合成氨和其他化工生产中,经常采用电极液位计来反映各种设备内导电介质的液位。这是利用电介质与电极的接触(或离开)形成电路构通(或断开)的原理来使声光
In ammonia and other chemical industries, electrode level gauges are often used to reflect the level of conductive media in various devices. This is the use of the dielectric and electrode contact (or leave) to form the circuit through (or disconnect) principle to make the sound and light
