摘要： A level measuring device with an integratable lens has a radar level meter and an angle adjusting assembly. The radar level meter has a horn antenna and a lens antenna assembly mounted on a signal transceiving end of the radar level meter. The lens antenna assembly has a housing and a lens antenna. The housing is hollow and receives the horn antenna therein. One end of the housing is connected to the lens antenna, and the other end of the housing is connected to the signal transceiving end of the radar level meter. The angle adjustment assembly is mounted around the housing. As the lens antenna assembly covers the horn antenna, the horn antenna is less likely to be damaged. Additionally, the housing of the lens antenna assembly is connected with the angle adjusting assembly for angle adjustment of the combined horn antenna and lens antenna assembly.

摘要： A rotary paddle level switch has a housing, a driving unit, two switches, a resilient member, a clutch, a transmission shaft, and a propeller. A resilient clip of the clutch holds a non-circular actuation section of the transmission shaft. When the driving unit drives the clutch to rotate, the transmission shaft and the propeller are driven by the clutch. When the propeller is rapidly rotated by suddenly exerting an excessively large external force thereon, as the resilient clip holds the transmission shaft by elastic force, the fast rotating transmission shaft removes itself from the holding of the resilient clip and is rotated without driving the resilient clip to rotate, thereby avoiding the transmission of the external force and damage to the driving unit. As the clutch just needs a clutch stand and a resilient clip to achieve the foregoing function, the level switch is structurally simple and relatively inexpensive.

摘要： A sealing device of a level meter is acid-and-alkali-resistant and pressure-resistant, and has a flexible outer tube, a plug, a female union connector and a male union connector. The flexible outer tube has an expansion neck formed on a bottom end thereof. The plug is mounted in the expansion neck. The female union connector is mounted around the expansion neck. The male union connector engages the female union connector by means of threaded engagement. The male union connector has a through hole for tying a weight such that the flexible outer tube is stretched along a force of a gravitational force of the weight. As being wholly and uniformly subjected to the gravitational force of the weight, the male union connector is less damage-prone. Accordingly, the tensile strength of the level meter is effectively increased, and a life duration of the level meter therefore prolongs.
