Our favorite EZO by far!  The FLO EZO is compatible with any flow meter with a 5VDC square pulse output signal.

To connect a flow meter, land the wire ends on the sensor bridge inside the WaterFeature# device.  5VDC power for the meter is available as well as signal and ground terminals.  Connect the header pins with one of the provided jumpers to "unisolate" the ground signal.

Even funner is eight flowmeters on a WaterFeature8.  It's not the craziest thing we've ever done, but its darn close.

5VDC Output


13.97 mm (0.55 in) x 20.16 mm (0.79 in) x 10.8 mm (0.4 in)

Care Instructions

Limit the chance of electrostatic discharge (ESD) damage by grounding yourself to earth ground before handling EZOs.

  • Bundle-able!

    Can be added to any WaterFeature# custom configuration. Go to the WaterFeature# product you want to bundle, select "CONFIGURE," and add this product to the configurator.

  • Genuine Atlas Scientific Parts

    We are an authorized reseller of select Atlas Scientific components. We think their EZOs are the beez knees, and the WaterFeature# line of products is designed to be compatible with all standalone EZO circuits as well as most sensors with built-in EZOs.

  • Consider Temperature Compensation

    pH, ORP, EC, and DO probes benefit from temperature compensated readings. Add an RTD EZO and RTD probe to any WaterFeature# configuration to unlock the built-in temperature compensation feature.

  • Consider Voltage Isolation

    pH, ORP, EC, and DO probes and EZO sometimes may influence each other, particularly in aggressive waters. Add Voltage Isolation to each pH, ORP, EC, and DO channel that needs to have unaffected readings.
