Chemical / Additive injection

The wide rangeability and low flow accuracy features of Max-Meters make them the leading choice for measuring on-line, liquid additive applications. The application profile is wide and varied, involving industries as diverse as facial tissue, cosmetics, petrochemical and aluminum.

The common theme of all of the Max additive applications is that a relatively small amount of fluid material is added or blended into the main product stream. Since the additive component changes or adds certain desirable characteristics to the final product, the formulation must be precise. Further, since this formulation is done "on-the-fly" and not through batch processing; final product quality is dependent on high resolution, repeatability and accurate metering over the entire operating range.

Max Equipment Specified: The Max 213 and Max 214 flow meters have small displacements which greatly boost the number of pulses per dose or milliliter. This degree of resolution gives the operator the ability to precisely dose the liquid into the process or fine tune flow rates and alarm limits to perfect the closed-loop flow control.

APPLICATION PROFILE:

Intermittent injections are not a problem.  The Max meters are precise volumetric displacement devices which are not affected by flow profile or turbulence.  Abrupt Starts and Stops in the flow rate do not impact the meter’s fixed displacement, the key to its high repeatability.  To deliver the most reliable signal, the Max meter uses a state of the art encoder with an anti-dither function to prevent over reporting of flow due to check valve leakage or pump drawback.  See how a Max meter can improve your process.   For sprays, pump injection or trickle flow rates, Max meters deliver accuracy where others cannot.
