Level measurement in containers with agitators: how to avoid periodic fluctuations in the liquid level

If a pressure-type level gauge is used, dealing with stirring is simple: first, a sleeve is used to dampen the disturbances caused by stirring; the level gauge probe is inserted along the tube to make contact with the liquid. Within the sleeve, there is only a gentle rise and fall of the liquid column, resulting in a quasi-static condition. II. By using a liquid-gas isolation sensor with a diaphragm that does not come into contact with liquid for pressure measurement, and by converting hydraulic pressure into gas pressure, the process of pressure transmission results in a second level of damping. III. Enable the digital filtering function of the level gauge; set the filtering strength coefficient based on the stirring speed to smooth out the raw measurement values. This represents the third level of damping, also known as digital damping. With these three levels of damping, the signal output by the level gauge becomes stable; it’s just as reliable as ****, and can be considered an invincible fighting fortress. {:2_34:}
