On-line monitoring device for liquid hazardous chemical substances

Abstract

The invention relates to an on-line monitoring device for liquid hazardous chemical substances. A main body comprises a measuring unit and a displaying unit. The measuring unit connected to the displaying unit by a wire consists of a mounting flange, a sleeve fixed at the mounting flange, and a box arranged at the sleeve. The displaying unit includes a case body. A pressure sensor is installed at the bottom of the sleeve; a temperature sensor and a hall liquid-level measuring element are installed inside the sleeve; and a floating ball body sleeves the outer side of the sleeve. One end of the wire is installed inside the box and the other end passes through the case; the wire is connected to a partitioning module arranged inside the case body; the partitioning module is communicated with a temperature display device, a pressure display device, and a liquid level display device respectively; the liquid level display device is connected with a container conversion module; the container conversion module is communicated with a volume display device. According to the on-line monitoring device, real-time online collection of relevant data like the liquid level, temperature, pressure, and volume inside a tank body can be realized; and the installation becomes simple, usage becomes convenient, and the precision is high.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to an online monitoring device for liquid hazardous chemicals. Background technique [0002] Oil tank trucks can be seen everywhere in daily life. Oil tank trucks are mainly used for transportation and storage of gasoline, diesel, kerosene and other liquid media. Therefore, compared with ordinary transportation vehicles, it is more necessary to monitor the internal liquid level, temperature, Pressure and volume, so liquid level gauges, thermometers, pressure gauges, and volume measuring devices are used on tank trucks. If such multiple measuring devices are introduced into it at the same time, it will inevitably cause certain difficulties in installation. At the same time, relative detection When testing, it must go through different paths, and the detection is relatively difficult. At the same time, the operation and maintenance cost will increase accordingly, which i...

If such multiple measuring devices are introduced into it at the same time, it will inevitably cause certain installation difficulties. At the same time, relative detection When it is necessary to go through different paths, the detection is relatively difficult, and the operation and maintenance cost will increase accordingly, which is not conducive to long-term use
