U系列超声波物位变送器

U Series Ultrasonic Level Transmitter

超声波物位变送器是近年来应用较多的一种物位测量仪表,但在有粉尘、雾气、泡沫的情况下无法应用,美国索尔公司U系列超声波物位变送器采用了一些新技术,如高能量超声脉冲发射、低频声波、回波辨识、声速温度补偿等,可以在上述场合成功应用,本文主要介绍该系列物位变送器的原理及应用。

Ultrasonic level transmitter is a more applicable instrument, but it cannot be used in the case of dust, foam, liquid vapor. U series ultrasonic transmitter of SOR adopts new techniques: powerful transmitted pulse, lower frequencies, echo recognition, temperature compensation of sound velocity. So U series ultrasonic transmitter can be used above-mentioned case.
