Abstract
A flexible float-type liquid level measurement device includes an outer tube securement member, a signal connection module, a flexible outer tube, a suspension member, a flexible supporting unit and a magnetic floating ball. The signal connection module is arranged on one end of the outer tube securement member. The flexible outer tube is connected to the outer tube securement member. The suspension member is connected to another end of the flexible outer tube. The flexible supporting unit is arranged inside the flexible outer tube, and the flexible supporting unit includes one end connected to the outer tube securement member and another end connected to the suspension member. The magnetic floating ball is moveably mounted onto the flexible outer tube. Accordingly, the elongated deformation of the flexible outer tube can be prevented while the measurement accuracy and useful lifetime of the measurement device can be increased.
