Patent number: 10228274Abstract: A liquid level sensing apparatus (10) for long-distance automatically enhancing a signal-to-noise ratio is applied to a measured target (20). The liquid level sensing apparatus (10) includes a sensing module (102), a long-distance command receiving module (104) and at least a brake module (106). The sensing module (102) transmits a sensing signal (108) to the measured target (20). The sensing signal (108) touches the measured target (20) to reflect back a reflected signal (110). The sensing module (102) receives the reflected signal (110) to measure the signal-to-noise ratio and to measure a height of the measured target (20). The long-distance command receiving module (104) is electrically connected to the sensing module (102). The long-distance command receiving module (104) receives a long-distance command signal (302). The brake module (106) is mechanically connected to the sensing module (102).Type: GrantFiled: September 13, 2016Date of Patent: March 12, 2019Assignee: FINETEK CO., LTD.Inventors: I-Chu Lin, Yao-Chen Yu, Chao-Kai Cheng, Yi-Liang Hou

Publication number: 20180106886Abstract: A radar level transmitter (1, 1a) includes a detection body (10, 10a), an antenna body (20, 20a) and a film sheet (30, 30a). The detection body (10, 10a) has a circuit board (12) being capable of emitting signals of detection and receiving reflected signals. One end of the antenna body (20, 20a) connects with the detection body (10, 10a). The film sheet (30, 30a) is combined with the antenna body (20, 20a) and covers another end of the antenna body (20, 20a); an airflow passes through the film sheet (30, 30a) for being capable of removing dusts adhered to the film sheet (30, 30a). Therefore, a radar level transmitter (1, 1a) with dust removing structures is achieved and a regular cleaning by personnel is not necessary.Type: ApplicationFiled: October 14, 2016Publication date: April 19, 2018Inventors: I-Chu LIN, Yao-Chen YU, Chao-Kai CHENG, Yi-Liang HOU

Patent number: 9568373Abstract: A cable-base sensor can detect a material level and temperatures of a material stored in a silo. The cable-base sensor comprises an electronic box, a cable, a stopper, and a signal processing module. The electronic box comprises a base and a space for containing the signal processing module, and a hole is formed through a bottom of the electronic box. The base is mounted in the bottom, and a tapered hole is formed through the base. A first end of the cable extents into the tapered hole and the hole, and spreads to form a cable bud. The stopper is a tapered block and pressed into the tapered hole for enforcing the cable bud to be sandwiched between the stopper and the base. The cable bud strengthens a connection between the electronic box and the cable for preventing damages from solid materials.Type: GrantFiled: March 6, 2014Date of Patent: February 14, 2017Assignee: Finetek Co., Ltd.Inventors: Chien-Lung Huang, Sheng-Shou Chen, Tzu-Chuan Tsai, Yao-Chen Yu, Chao-Kai Cheng, Ting-Kuo Wu

Patent number: 9404787Abstract: 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.Type: GrantFiled: February 26, 2014Date of Patent: August 2, 2016Assignee: FINETEK CO., LTD.Inventors: Shu-Chien Cheng, Chien-Lung Huang, Tzu-Chuan Tsai, Yao-Chen Yu, Ting-Kuo Wu, Chao-Kai Cheng
