Buoy water calibration method
Thread Content
For float level measurement, when the density of the medium at the level or interface is greater than that of water, 475 is commonly used. How does everyone carry out the calibration?
When adjusting the liquid level with a float, set the zero point during venting, and then calibrate the range using two points. For this calibration, first confirm 0 when the tank is empty; thereafter, add water to the float according to the ratio between the actual medium and water density, until the desired proportion is reached and 100 is confirmed. Once the float is in use, compare it with the on-site liquid level gauge to adjust for any errors
For calibrating the level, the two-point calibration method is used to determine the zero point; in this process, a float with a low density is utilized, and the zero point is confirmed by filling water based on the ratio between the density of the light medium and that of water. Subsequently, the zero point is confirmed again by filling water based on the ratio between the density of the heavy medium and that of water. After the float is put into use, its deviation also needs to be adjusted
