LEVEL MEASURING APPARATUS IN TANK

摘要

A liquid level measuring device for a tank is provided to recover scattered liquid into a tank without flowing back into a differential pressure measuring pipe, thereby obtaining a precise liquid level in the tank. A liquid level measuring device for a tank includes a tank(10), a differential pressure measuring pipe(20), a differential pressure sensor(30), and a reservoir(40). The tank stores liquid(11) inside and discharges the liquid. The differential pressure measuring pipe connects the upper and lower parts of the tank to each other. The differential pressure sensor is connected to the differential pressure measuring pipe at the connection position between the differential pressure measuring pipe and the tank. The reservoir is connected to the differential pressure measuring pipe at an upper part of the tank and has an internal space for introducing the liquid scattered in the tank.
