Liquid level gauge
Thread Content
What are the calibration methods for float level gauges? Answer: There are two main methods: liquid filling method and hanging weight method. ①The method of liquid calibration is generally used on site. If the liquid to be measured is not water or alcohol, water or alcohol can be used for calibration through density conversion. ②During maintenance, the hanging weight verification method can be used. During calibration, remove the float, hang the weight plate, calculate the values of the starting end, middle and end of the float, and add weights for verification.
During the maintenance period, the water school method is usually used on site. It is estimated that not many people will adopt the second method mentioned.
The first type is basically used on site, and alcohol is rarely used for effectiveness. It is so expensive. They all use the water method.
Generally, water is used for calibration. There are two methods of hanging weight: internal hanging and external hanging. Details can be found on Baidu. I have always suggested that if you have complicated questions, ask the forum, and simply find a girl!
Water should be relatively common and reliable, right?
