Counts and sizes water-borne particles down to 2 microns
CounterSense & FilterSense Particle Counters
Online Water Analyzer from Process Instruments (Pi)
Online water particle counter for clean water treatment including water particle counters, particle analyzers, water particle size analyzers, and more from Pi.

About CounterSense & FilterSense Particle Counters
The Water Particle Counter range from Pi is the first in the world to be able to mount multiple water particle counting sensors on a single controller. The CounterSense is a sophisticated online water particle counter with the capability to size and count particles from 2-127 microns and to count from 2-750 microns. The FilterSense has the capability to size and count particles from 2-127 microns. Both the CounterSense and the FilterSense are connected to a CRIUS4.0 or a CRONOS which can also connect other sensors including more particle counters.
The range of sensors are available with different controllers giving you the same great performance with different communication, display, and control options.
With the Pi range of controllers, you get everything that you need – and nothing that you don’t, without sacrificing the quality of measurement. Each sensor comes with a ‘clean me’ alert and can be run with a constant head weir or a flow meter, to maintain a constant flow.
Why choose CounterSense & FilterSense Particle Counters
Optimize Cryptosporidia and Giardia removal
Reports both particle counts and size distribution
Sapphire optics for extended life
User calibration for lower cost of ownership
Ultra-clean medical device washing monitoring
