Cylinders should be filled using?

Filling cylinders using the weight or volumetric method ensures accuracy and safety. This approach involves measuring the amount of gas being filled based on its weight or the volume being transferred. By calculating the total weight of the cylinder before and after filling, or by using volumetric measures, it ensures that the correct amount of substance is loaded without exceeding the cylinder’s rated capacity.

This method is particularly important in maintaining the integrity and safety of gas storage. Overfilling can lead to dangerous situations, such as exceeding pressure limits or causing leaks. The weight or volumetric method offers precision, which is critical in applications where exact measurements are necessary for performance and safety.

Other methods like the pressure method may not provide as accurate a measure due to fluctuating environmental conditions affecting pressure readings. Visual inspection does not offer reliable quantification, making it unsuitable as a primary filling method. Time-based filling lacks the precision required for maintaining safety standards, as it does not account for variables such as flow rate variations.
