Welcome to Pascal Control | Malaysia Valve Supplier
LUGB & LUCB Vortex flowmeter work on the principle of generated vortex and relation between vortex and flow by theory of Karman and Strouhal, which specialize in measurement of steam, gas and liquid of lower gas and vapor even turbid liquid including micro grain and impurity. Vortex Flowmeter is on the principle of Karman Street, to measure liquid, sides with opposite directions of rotation, Vortices frequency is directly proportional to medium velocity. Through numbers of vortices that is measured by sensor head, medium velocity is calculated, plus flowmeter diameter, final volume flow come out.
