Case Studies

Case Studies

Municipal Pump Station Upgrade

A city utilities team evaluated converting legacy pumps to higher efficiency models.

Scenario

Specifications from suppliers arrived in mixed units, including m³/h, GPM, and CFM, complicating bid comparisons.

Solution

Used the flow rate converter to normalize all vendor data into cubic meters per second for a unified review.

Result

Enabled an apples-to-apples comparison that produced a 22% energy savings recommendation.

Chemical Dosing Accuracy

A pharmaceutical facility needed precise low-flow conversions for sterile dosing lines.

Scenario

Engineers worked with specs in L/min but control systems required input in m³/h.

Solution

Adopted standardized conversion tables generated from the tool for calibration procedures.

Result

Improved dosing accuracy to within 0.5% and simplified audit documentation.

Irrigation Network Planning

An agritech startup mapped irrigation requirements across varied crop zones.

Scenario

Design teams switched between drip emitter L/hr specs and pump supplier GPM ratings.

Solution

Integrated the flow converter into their planning software for instant cross-unit calculations.

Result

Achieved a 30% reduction in water use while maintaining crop yield targets.
