Abstract

The invention provides a differential-pressure type anti-freezing liquid level meter. A positive-phase pressure-guiding pipeline of a differential pressure gauge is led out of a cooling tower at a certain height, and is led from the inner wall of an equipment container to the bottom part thereof; a measured medium is not in direct contact with a positive pressure chamber of the differential pressure gauge, and air or nitrogen in the remained gap is used for pressure conduction; and quantitative anti-freezing liquid is filled into the part of the positive-phase pressure-guiding pipeline out ofa stop valve of the cooling tower. By adopting the differential-pressure type anti-freezing liquid level meter, the problems that the positive-phase pressure-guiding pipeline is frozen and blocked and the measured medium is crystallized or condensed after being subjected to temperature changes are effectively solved.

Description

technical field

[0001] The invention relates to a differential pressure antifreeze liquid level gauge in industrial production, which is especially suitable for water level measurement in air cooling towers and water cooling towers in air separation devices, as well as liquid air in the lower tower and main cooling liquid oxygen liquid in the upper tower. bit measurement. Background technique

[0002] In industrial production, it is often necessary to measure and control the liquid level of some equipment and containers. There are two main purposes of liquid level measurement: one is to ensure the quantity of raw materials, semi-finished products or finished products in the container through liquid level measurement, so as to ensure the continuous supply of materials required in each link of production or to carry out economic accounting; the other is to pass Liquid level measurement, to know whether the liquid level is within the specified range, so that the production can...
