 Using Gears, Inc.’s optional modular
admixture delivery system, the AccuMix™ 750XB can dispense a liquid additive
into the water delivery system for optimum dispersion through the mix.
This system is controlled and powered by the plant.
Admixture is pumped from an outside container by means of a 1/4" or
1/2" Ingersoll-Rand Aro pneumatic pump. The pump size is dependent upon the
fluid properties and proportion. The
admixture then enters an Aro Shock-Blocker pulsation damping system to achieve a
completely consistent flow. A check
valve is installed before the admixture enters the water delivery system to
prevent any cross contamination of supplies.
As with the water, admixture is measured by an Endress+Hauser Promag 33A
Electromagnetic Flow Meter. Because
this mag-meter has an open flow tube, it is ideally suited for admixtures, which
tend to clog up or decrease the accuracy of traditional meters. As long as the fluid has a minimum conductivity of 5 mS/cm, no calibration is required and the meter
will provide better
then ± 1/2 % accuracy
(manufacturer’s specifications available upon request).
