How do I use a flow meter to monitor cocopeat irrigation?

A meter is most useful when readings are linked to a specific zone and event.

THE COCOPEAT CONNECTION

Why the root zone matters

Measured supply volume helps interpret drainage and moisture changes in a coir crop.

01 / OBSERVE

Three checks before you change anything

  1. Record meter units and whether totals include other water users.
  2. Compare delivered volume with the zone’s emitter count and collected output.
  3. Check repeatability during a stable event before relying on alarm thresholds.

02 / NARROW IT DOWN

What does the meter represent?

Choose the closest observation for a suggested next check.

One dedicated zone

Build an event baseline and review unexpected departures.

Several zones together

Record which zones overlap or add zone-level measurement before comparing crops.

Units are unclear

Confirm the unit and pulse scaling with the installer before using calculated litres.

03 / TAKE THE NEXT STEP

Leave with something useful

Keep the raw meter reading alongside the controller duration.

Keep in mind

An incorrect pulse multiplier can make a reliable meter display a misleading calculated total.
