Magnetic flap level gauge, Level refers to the storage container or industrial production equipment in the liquid, powdery solid or immiscible liquid between the two kinds of density due to the formation of the interface position. Liquid medium level is called the liquid level; Liquid-liquid (two different density and immiscible liquid) or liquid-solid interface between the surface known as the interface; Solid particles and powder accumulation height called material level.
Liquid level measurement has an important position in industrial automation system, is the important parameters to ensure the continuity of production and equipment safety. In the case of continuous production, the maintenance of the level of stability in the certain equipment (such as steam boilers, evaporators, etc.) is essential for factory to ensure the safety of production and equipment. For example, large-scale boiler water level fluctuations are too large, in the absence of water dozens of clocks, it may have the risk of drying.
Although the choose and usage have the close relationship with the production process, the main purpose of the usage of the liquid level instruments is below:
1. The correct measurement of the volume or weight of the material stored in containers, that is, the purpose of liquid level measurement is used for measurement and economic accounting.
2. To monitor the container level, the upper and lower limit alarm for which the liquid level allows, that is not continuous detection and output level of the specific value, as long as the output level of the switch signal.
3. Continuous monitoring of production and regulation, the liquid level to maintain the required height, that is required for liquid level detection instrument for continuous output level of the instantaneous signal value.
