ADDMAS Advance Orifice Plate Based DP Flowmeters
Minimum Order Quantity: 1
1 Pack contains : 1 Unit
• High Accuracy Structure with the multi hole could balance the flow field, reduce the vortex shake and signal noise, substantially improve the stability of flow field, make the precision improved tenfold than orifice plate, repeatability reach to 0.1%.
• The lower requirement of straight pipe, because of stable flow field and twofold pressure recovery than orifice plate, the straight pipe least could less than 0.5D, which could save a mass of straight pipe, especially expensive ones.
• Reduce the permanent pressure loss. The design of multi-hole symmetry decrease the sheer force of turbulent flow and whirlpool shape, reduce the energy of motion loss, and save the pretty big cost of operation energy.
• Directly replace the orifice plate. Be familiar with the use method and appearance of the orifice plate, which allows direct replacement and adjust to the energy metering reform of changing orifice plate into series balanced flow meter.
• Resistant to smudginess and blockage. Balanced design of porous and asymmetric structure reduce the retention shape and assure dirty mediums flow through the holes.
• Wide measuring range
• Reynolds number least to be less than 200, maximum greater than 107, β 0.25~0.9
• Long-term and good stability
Apparent decreasing of turbulent flow shear force drastically reduce the rub of mediums and throttling part, the stable β number and nonmovable parts keeps the long-term stability.
• High temperature and pressure measuring. MAX Working temperature 850, MAX working pressure 42 Mpa.
• Complex working conditions measuring. Special structure design enables its special functions, which allows to all the measurements of gas-liquid two-phase mediums, all kinds of mixed gases, all kinds of lower temperature gases, stuff, multi-phase stream, vibrative stream, electromagnetic interference mediums and bidirectional flow.
