UQD型浮球液位变送器

UQD型浮球液位变送器由测量部分和信号控制器部分组成，测量部分由浮球、平衡杆和平衡锤组成力矩平衡机构，浮球会跟随液位的变化而升降，控制器据此输出相应的标准信号。可广泛适用各种介质的液位测量，是石油、化工、冶金、电力行业的理想仪表。

The UQD floating ball liquid level transmitter consists of a measurement part and a signal controller part. The measurement part consists of a torque balance mechanism composed of a floating ball, a balance bar, and a balance hammer. The floating ball will rise and fall according to the changes in liquid level, and the controller will output corresponding standard signals accordingly. It can be widely used for iquid level measurement in various media and is an ideal instrument for the petroleum, chemical, metallurgical, and power industries.
