Pi’s range of water quality analyzers combines quality of results with ease of use and reduction of maintenance. This allows the user to be confident of the data and information recorded. The quality of water produced at a Water Treatment Plant depends on the control of the process which in turn depends on the quality of the data coming from the sensors. Pi uses the best sensors currently available in the world to ensure that that data, and therefore the quality of the water produced, is the best it can possibly be.

With added extras such as control (PID and others), data logging, remote access, and sophisticated comms such as Profibus and Modbus, the Process Instruments analyzers are increasingy used all over North America.

With particular expertise in coagulation control, chlorine and disinfection monitoring, Pi analyzers and controllers are currently being used in over 200 North American WTPs. Contact us and see what we can do for you.

Coagulation Control

The pHSense range of online pH meters from Pi utilize the very latest and best pH sensors available. With self-cleaning options, inline and atline flow housings and options for low conductivity cold water, talk to Pi to resolve any pH monitoring issues you have.

Streaming Current

Previous
Next

A Streaming Current analyzer effectively detects residual coagulant in a Water Treatment plant and can be used for control of coagulant dose or simply as an alarm that tells you if you are over or under dosing coagulant.

Turbidity

Previous
