Issues with the materials of glass plate level gauges
Thread Content
I would like to ask the teachers: when it comes to replacing the glass plates in a glass plate level gauge, are these glass plates standard components? What are the various sizes and models available? Additionally, I would like to replace the upper and lower ball valves of the glass plate level gauge separately. I’m not sure if they are available for purchase, and I wonder how to prepare a material request Thank you! ! !
