Flow rate to flow meter frequency

Set these parameters: “Calibration pulses per liter”. In Numloom, enter “Flow rate in liters per minute” (L/min) to obtain “Flow meter pulse frequency” (Hz).

Calculations currently require access to Numloom on Google Play Internal Testing. iPhone and iPad support is planned.

Editable starting values, not standards or manufacturer recommendations. Check the values for your material or equipment.

How it works

Flow meter pulse frequency = Flow rate in liters per minute × Calibration pulses per liter ÷ 60

In Numloom: “Flow rate in liters per minute” → “Flow meter pulse frequency”.

L/min → Hz

Calibration pulses per liter · pulses/L

This page shows the formula and parameters. The calculation runs in Numloom.

Assumptions and limits

Calculation basis: “Flow rate in liters per minute” (L/min) → “Flow meter pulse frequency” (Hz). Use the parameters shown for this particular operation.

Use the pulse factor calibrated for the actual meter. Frequency, pulse count and flow rate are different inputs; keep the displayed volume and time units.

Enter a non-negative value in the app.

Coefficient sources

Initial settings: Calibration pulses per liter = 100 pulses/L (example in the original task description).

These starting values are not a standard, calibration certificate or manufacturer recommendation. Replace them with values measured for your process or specified for your product.
