发明名称 CAPACITANCE TYPE LEVEL METER
摘要 PROBLEM TO BE SOLVED: To provide a capacitance type level meter which has an advantage to maintain a high precision in detection accuracy of the height of liquid level by preventing sticking of a dust on an electrode rod. SOLUTION: An electrode rod 40 is so arranged as to be inserted into a water level detecting container 18, including a core material 42 and a tube body 44. The core material 42 is formed from a material having conductivity. The tube body 44 is made of a material having insulation properties, heat resistance properties, a high breakdown strength, and a chemical resistance, to cover the lower end of the core material 42 as well as the outer peripheral surface 4204 of the core material 42. The case 48 houses the electrode rod 40 and forms a space 52 which allows circulation of boiler rotor for detecting water level together with the tube body 44. A floating body 46 is housed in the space 52 in such state as prevented from flowing out of the space 52, and floats on the water surface of the boiler water circulating the space 52. The floating body 46 vertically moves while following the change in level of the water surface in the space 52 to contact to the outer peripheral surface 4412 of the tube body 44.
