Basic concepts of level measurement
2011-3-9 9:57:51

Material level occupies an important position in chemical production. With the continuous development of the production process, the expansion of equipment, computer centralized control and management, remote transmission and measurement of material level become more important. For example, in rubber production, liquid level measurement and control of high viscosity media, autoclave liquid level measurement.

Definition of level

Generally, the liquid height or surface position stored in the storage tank, storage tank, various towers and other containers during the production process is often called the liquid level. The height or surface position of solid blocks, granular powders stored in storage tanks, hoppers, and warehouses is called material level. Another example is the position of liquid level and liquid phase interface. The position of liquid level and solid phase interface is called interface.

We refer to the above-mentioned liquid level, material level, and interface position as the material level. The automatic instrument used for level measurement, alarm and control is called level measuring instrument.

Purpose of level measurement

The purpose is to determine the number of raw materials, semi-finished products or finished products in a container or tank by means of level measurement. Another purpose

The level is used to reflect whether the continuous production process is normal or not in order to reliably control production. Such as the level measurement of boiler drums and

Control is an indispensable condition to ensure safe production. The lowering of the boiler water level will cause tube explosion or explosion. Synthetic ammonia production

The liquid level at the bottom of the copper washing tower is too high, and the liquid gas contained in the refining gas causes CO, HS, etc., to poison the synthesis tower with coal; the liquid seal is lost when the liquid level is too low

Effect, causing the high-pressure flushing regeneration system to cause the regeneration tower to explode.
