1. General Introduction
RAKD variable area flow meter is mainly for special application is in troubled, opaque or aggressive mediums and under high pressure. The instrument is mounted in a vertical pipeline with flow direction upwards. A float is guided concentrically in a conic metal tube. The position of this float is magnetically transmitted to the indicator. When the process conditions are changed the scale needs to be replaced by a new one of which the values should be calculated.
Besides, RAKD variable area flow meter come with several outstanding features as: Different process connections like internal threads and flanges, With fine control valve (horizontal connection) and without valve (vertical connection), All wetted parts of stainless steel AISI 316Ti (1.4571), Round industrial standardized stainless steel housing with degree of protection IP 66/67, Light, guided floats resulting in low pressure loss and stable float movement and etc.
