1) Due to fluid surface mechanics, i.e., reversal of the meniscus surface when changing from rising to falling liquid levels or vice versa, a hysteresis effect occurs in the measurements. To minimize this, the user should prepare the inner surfaces of the separator in accordance with section: Cleaning and Preparation.
