Article source:How to measure the residual amount of liquid nitrogen in the liquid nitrogen tank? Hits:122 Release time:2023-03-07
The liquid nitrogen tank is widely used in the field of liquid nitrogen and is welcomed by many staff. However, we often encounter some problems in the process of using it. One of the most common problems is how to check the residual amount of liquid nitrogen in the liquid nitrogen tank. Let's take a look at this problem:
1. Weight reduction method:
First, weigh the weight of the empty tank, then weigh the weight of the entire liquid nitrogen tank when it is filled with liquid nitrogen, then subtract the weight of the empty tank to get the total content of liquid nitrogen, and then weigh the weight every 3-5 days to get the remaining amount, but this method is time-consuming and laborious.
2. Wood stick frosting method:
Take a long wooden stick of about 80 cm, coat it with black after peeling, and then set a scale every 5 cm from the beginning of a section. When measuring, insert the zero scale downward from the tank mouth to the bottom, and remove it after 5~10 seconds. The frost length is the liquid nitrogen level in the tank, but this method has a large error and is not safe.
The above are two methods to measure the residual liquid nitrogen in the liquid nitrogen tank. Both methods have advantages and disadvantages. You can choose according to the actual situation.
