Application
Tips: Can the mechanical flow meter be used for water or corrosive liquids?
This model is specifically designed for petroleum-based fuels like diesel, gasoline, and kerosene. Using it with water or corrosive liquids is not recommended, as it may cause internal rusting, seal damage, or gear failure. If you need to measure water or chemicals, look for models with corrosion-resistant materials (e.g., stainless steel or Teflon-coated internals) that are certified for those media.
