1 Rua das Cerejeiras, 80 Ressacada CEP Itajaí SC Fone: (47) Medidor de Vazão tipo Vortex Série MTGB All welded, non-clog design provides maximum performance, reliability and enhanced safety by eliminating ports and gaskets. No seals, just steel. Available with optional output. Internal temperature compensation provides cost-effective saturated steam mass flow measurement. Adaptive Digital Signal Processing provides vibration immunity and flow range optimization. Vortex extends the measurable flow range, reduces installation costs, and minimizes project risk. Available in wafer, flanged, and high pressure designs.

The dimension above is only for selection reference, actual dimension will be subject to approval when order. 2. Normal seamless steel tube diameter is metric system, imperial system should be specified before order. 3. Pipe butt welding, thread connection, clamp connection, fixed plug-in, ball-valve plug-in, high temperature, ultra-low temperature will be subject to approval when order. 4. Mounted flanges adopt GB/T standard, special requirements (ANSI, DIN etc) should be marked before order.

8 Installation type selection Wafer Preferred type Compact structure Easy installation Short delivery time Wide use Flange Used for integral differential pressure, temperature, pressure compensation. 2 Pipe butt welding and clamp Used for high pressure medium Thread Used for small pipe size and sanitary type Used for big pipe size. Fixed plug-in type is preferred selection Fixed plug-in and ball-valve plug-in because of easy installation and low cost. Ball-valve plug-in is mainly used for dirty medium, scaling and regular clean

9 Measurement range selection Structure Type Nominal Diameter Flow range (m3/h) Liquid Gas Steam Pipe type Insertion type

10 Compensation type selection Differential pressure compensation The type is not affected by medium components or the change of dryness. It is especially suitable for measuring unstable component mixed gas, liquid, high humidity steam and water vapor contained. Temperature compensation This type is mainly suitable for measuring mass flow rate of stable pressure saturated steam Pressure compensation This type is mainly suitable for measuring standard flow rate of stable temperature gas and mass flow rate of steam. Temperature and Pressure compensation This type is mainly suitable for measuring mass flow rate of steam and standard flow of gas.
