を液面に直接接触させることが好ましくないという欠点
があった。The conventional device described above has a drawback in that it is not preferable to bring the sensor into direct contact with the liquid surface for liquids that require sanitary properties such as high viscosity liquids, electroless liquids, and chemical liquids.
本発明は上記欠点を除くためになされたもので、センサ
を直接液面に接触させることなしに水位を検知すること
ができる密閉タンクの水位検出装置を提供するものであ
る。The present invention has been made to eliminate the above-mentioned drawbacks, and provides a water level detection device for a closed tank that can detect the water level without directly bringing the sensor into contact with the liquid surface.
本発明に係る密閉タンクの水位検出装置は、液体と加圧
気体とを貯留した密閉タンクに、液体の圧力と気体の圧
力との差を検出する差圧検出器を設けたものである。A water level detection device for a closed tank according to the present invention is a closed tank that stores liquid and pressurized gas, and is provided with a differential pressure detector that detects the difference between the pressure of the liquid and the pressure of the gas.
