ChemFlow Systems has engineered and developed the concept of “U-Tube” technology. Their patented “Adjustable U-Tube” technology allows for highly accurate and repetitive volumetric measurements. This innovative design acts as a simple side flow, gravity drain that naturally monitors the level within each mixing vessel. The U-tube is easily adjustable and positioned at various levels to give the desired chemical volume for mixing. The “U-Tube” technology has proven accurate, efficient, extremely reliable, and is incorporated in all ChemFlow Systems blending and delivery systems. Blending repeatability of <0.1%. No pumps or scales are used. Precision chemical/slurry delivery as low as 5 cc’s and mixing ratios up to 1000:1.
