Balanced orifice flow meter is also called adjustment flow meter, multi-void orifice flow meter. It is an upgraded version of conventional orifice flow meter. The size and distribution of the holes are customized based on special formulas and test data, which are called function holes. When the fluid passes through the function hole of the disc, the fluid will be balanced and rectified, and the vortex will be minimized to form an approximate ideal fluid. Through the pressure taking device, a stable differential pressure signal can be obtained. The volumetric flow rate, Mass Flow.
✮The measurement accuracy is better than 1.0 level
✮ Energy optimization, saving the energy loss of the entire pipeline system
✮ The rectification function makes the front and rear straight pipe sections shorter
✮ Greatly reduce pressure loss
✮ Increase the thickness of the throttling device to enhance the straightening function
✮ Pressure method: flange pressure; corner joint pressure; ring chamber pressure; travel pressure, etc.
✮ Process connection method: butt welding, pipeline, flange to clamp, etc.
