Are there any requirements regarding the installation location of the level gauge on the tank?

Apprentice. When designing the installation location of a level gauge on a tank, what factors should be taken into consideration? Please help, thank you
I’m not sure what type of level gauge you are using – a paddle level gauge or a differential pressure level gauge. The former is generally used in smaller containers, while the latter is typically used at the bottom of larger containers
Of course, it meets the requirements for level measurement.
Differential pressure level gauge, one at the bottom of the container and the other at the allowed maximum liquid level. This position should be calculated by the calculation process. A full tube test can be added if necessary. The piping layout also needs to be taken into account; it should be discussed with the piping specialists
For glass tube level gauges, external float level gauges, magnetic flip plate level gauges, and double flange level gauges, they are generally installed on the side of the container. The two sampling points should be located as far apart as possible, at the bottom and top of the container, so that the liquid level in the container falls within the range of the level gauge； In the case of internal float level gauges, radar level gauges, or radio frequency admittance level gauges, they are installed at the top of the container; the sensor is lowered from the opening at the top of the container to the bottom of the container, so as to keep the liquid level as much as possible within the range of the level gauge.
It’s a glass tube level gauge; does it require two sampling ports to be installed? One on top and one at the bottom.
For measurement and safety, there should be no blind spots.
Your question is too general; the requirements for each type of level gauge are different, and various factors need to be taken into consideration for each one
Glass tube level gauges, external float level gauges, magnetic flap level gauges, and double-flange level gauges are generally installed on the side of the container. The two sampling points should be located as far apart as possible, at the bottom and top of the container, so that the liquid level in the container falls within the range of the level gauge
Generally, a tank has a maximum allowable liquid level and a minimum allowable liquid level. The level gauge must meet these two levels. When installing level gauges as well, ease of use for operators must be taken into consideration. You can also refer to the approach used in standard diagrams.
