Design advantages of A+QMC balanced flowmeter for blast furnace gas

Thread Content

The A+QMC balanced flow meter and the standard orifice plate both belong to the differential pressure flow meter category, but they differ significantly in the design of the orifice opening at the throttling element. Standard orifice plates have only one throttling hole, and the dead zone surrounding this hole generates numerous vortices that consume the fluid’s kinetic energy; moreover, deposits of dirty material accumulate at the upstream edge of the throttling element, which over time leads to blockage of the pressure measurement holes ； The balanced flow meter, thanks to its porous disc throttling and rectifying design, **reduces the formation of dead zones, ensuring that dirty media can pass through the throttling orifices smoothly, thereby decreasing the likelihood of the pressure sampling holes becoming clogged.
