MEASURING GRID SGIfor air measurement in pipelines □ For measure speed after the dynamic pressure method □ Arrangement of several cylinder pitot tube □ Central tubes with laterally attached probe tubes □ Material brass (up to 100 °C) or stainless steel (up to 450 °C) □ Pressure connection 6mm □ Mounting parts available The SGI is a special lattice arrangement of a plurality of cylinder probes, which are distributed over a cross section that can be at different flow distribution in a pipe found in a canal or a mean flow. The probe is connected to the grid and each pipe or channel dimensions can be customized. It can be made for the edge or square channel cross-sections. For larger sizes is usually required a thrust bearing. Specifications Construction: central tubes with laterally attached probe tubes Pressure taps: 6 mm 0 plastic tubing for connection Grand calculation for cylinder position sensor and sensor grids: Comment: The use of the differential Peritact 80 (± 1.5%) with the smallest range of 0...1 mbar results as a range for the lowest velocity 0...8 m / s. The transmitter MKM (± 0.2%) and 2000-K10 Peritact (± 1%) with the smallest ranking of 0... 0.1 mbar as a result, the lowest range for velocity 0...3 m/s. Larger ranges are possible by adjusting the transmitter. w = velocity in m/s Ap = differential pressure in mbar p = density at actual conditions in kg/m3 C = coefficient for cylindrical probe = 2 for Prandtl-pitot tube = 1 Measuring grid SGI Dimensions material Other dimensions on request.
