<span style="font-weight: 400;">Consider the medium to be used, which often depends on the pressure range. Gas is ideal for lower pressures, offering cleanliness and reducing the impact of head height corrections. However, for higher pressures, water or oil are necessary. Liquids, being incompressible, allow for precise pressure adjustments. Mineral oil is commonly used but may introduce contamination, which can be addressed with water or liquid-to-liquid separators.
