OPTIMIZE METERING PUMP SPEEDS & LOOP CONTROLS

CONTINUOUS REGULATORY COMPLIANCE:
Many states require that metering pumps be operated within a specific zone of the pump turn down range. For instance, The Wisconsin Administrative Code states "metering pumps shall operate at 30-70% of their specified range and a minimum of 12 strokes per minute. If this is not possible, dilution of the chemical will be required." The Utah Administrative Code requires "fluoride solution shall be applied by a pump having a stroke rate not less than 20 strokes per minute." With dilution ratios of up to 1000:1 possible, the Merlin can turn a pump with a 10:1 turndown into a pump with an effective turndown of 10,000:1!!!




HIGH VOLUME / LOW STRENGTH MEANS BETTER CONTROL:
Although many metering pumps have a broad turndown ratio, they are more accurate and can help achieve better residual control when operating at the middle to upper end of the pump range. On demand dilution allows a higher volume/lower strength chemical to be fed. This allows for smaller incremental changes in chemical dosing, enabling tighter residual loop controls (i.e. pH., ORP, streaming current, chlorine) by reducing overshoot




SUPERIOR ACCURACY & REPEATABILITY:
A consistent and reliable chemical strength is paramount to achieving good residual loop control. The fully automated Merlin Dilution Controller can produce unparalleled accuracy and consistency by using instrument grade load cells coupled with a microprocessor based controller. Our unique patent pending design allows us to fine tune the dilution process to accuracies greater than 1/10th of 1% for each and every batch.
