Highest Quality - Low Cost - Superior FunctionalityPart of a range of controllers, the CRIUS® is the big brother of the CRONOS® and offers more sensor connections, more functionality and more flexibility with a colour screen and optional built in 3G modem. The CRIUS® is an attractively priced, top of the range instrument controller. Optional communications packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP and others. The CRIUS® is equipped with the capability to connect up to four sensors of any type with appropriate analogue outputs and relays. Four sensors not enough? Simply connect up to 4 CRIUS® together all using the same display and communications. Equipped with data-logging as standard and multiple PID loops as options, the CRIUS® is very able to control complex water treatment processes at a fraction of the cost of other controllers. With all users having their own log on, and with three levels of instrument and remote access security, you can use the CRIUS® with all of its superior functionality with confidence.

- Turbidity Meter (TurbSense®)
- Streaming Current Monitor (StreamerSense)
- pH Analyser (pHSense)
- ORP Analyser (ORPSense)
- Organics Monitor (UV254Sense)
- Biofilm Monitor (BioSense)
- Online Conductivity Monitor (ConductiSense)
- Particle Counter (CounterSense)

- Choose from Standard Configurations or ‘Build Your Own’
The CRIUS® is currently used in a multitude of applications including: Water Treatment for the control of, for example, Cooling Towers where the online biofilm control of the BioSense and the remote access capability is bringing solutions to our customers’ water treatment requirements. The CRIUS® is preferred in the Swimming Pools market, where the superior control and sensor capability provides for better quality bathing water. Again the remote access is proving essential to our customers along with the Variable Speed Drive (VSD) control which is massively reducing electricity usage and CO2 emissions (and reduces the electric bills!). In the municipal drinking water market, the superior control capability is making it the controller of choice for areas like coagulation control with the superior sensors in use particularly for chlorine control and dissolved oxygen control.
Summary of Applications
- Water Treatment
- Drinking Water
- Waste Water
- Pool and Spa Control
- Industrial Water
- Food and Drink
- Paper and Pulp
Small water treatment plants, secondary disinfection plants etc. tend to suffer from similar problems wherever they are in the world. The first is lack of communications SCADA infrastructure, the cost of which to install can be prohibitive. The second is the lack of a central DCS control infrastructure, again the installation of which can be cost prohibitive. The third is the remote locations. Often these water treatment plants are in remote and difficult to access locations. With these three issues facing many water engineers around the world, a low cost solution providing solutions to all three issues is available from Pi. A CRIUS® controller has the on board capacity to provide small scale SCADA, and full online PID control whilst the sensors (e.g. chlorine, pH, Turbidity etc.) are suitable for long term operation without operator intervention.

If you have used a Pi controller you will know that they give you unrivalled control options but did you know that Pi’s new controllers also offer individual security for up to 20 named individuals? Pi’s controllers have always given flexibility but did you know that Pi’s new controllers can accommodate up to 16 sensors of any description?This Focus On describes the 10 most popular innovations to be found in Pi’s new CRONOS® and CRIUS®.
No. 1 - Human readable service logBoth the CRONOS® and CRIUS® analyser/controller has a downloadable human readable service log - giving an entire history of the instrument including current settings, calibrations etc. Provides a great snapshot of how an engineer left an instrument.
No. 2 - Cloning FacilityEver had to set up many instruments with the same settings? Simply set up one and copy it to others!
No. 3 - On screen wiring diagramsLost the manual or can’t be bothered to find it? Pi’s analysers have the answer!
No. 4 - Want a bit more info on what’s going on with a sensor?Pi’s new sensor maintenance pages are just for you then! Detailed information about all aspects of the signal coming off the sensor clearly available.
No. 5 - Instrument datalogs not quite giving you what you need?Pi’s new look datalogs in CRONOS® and CRIUS® (downloadable) let you datalog almost everything, put graphs on the display, datalog the same parameters at more than one interval and a whole lot more. Never has instrument datalogging been so easy and complete.
No. 6 - New enclosureThe new enclosure brings a new level of flexibility being wall mountable, pole and handrail mountable and even flush mountable. Not only that, but it gives you loads of room to work in and there are even spare live, neutral and earth terminals to make wiring relays easier!
No. 7 - Not enough I/O?Don’t worry, simply daisy chain 4 CRIUS® together and you can use the same display, comms options etc. and increase your I/O fourfold to give up to 16 sensors.
No. 8 - Bored of reading about stuff in manuals that you don’t have?Pi’s new manuals are bespoke to each instrument. The manual is ‘built’ to match each individual instrument so the manual only has what you have!
No. 9 - Has the operator been messing with settings they shouldn’t?No more! With 20 individual user settable logons, you can give people access to what they need and no more.
No. 10 - Control algorithmsPi has developed a reputation for developing great control algorithms and this has continued with the new CRONOS® and CRIUS® with the introduction of feed forward control algorithms and a master controller which selects the correct control philosophy to use (for use with complex systems such as coagulation control).
You probably know that water monitoring controllers can be connected to site SCADA systems, but… … did you know that with Pi Remote Access you can change settings on the controller from your home or office without setting a foot out the door? … did you know that you can still access the controller, even if it’s in an area with no network signal?Pi’s Remote Access server draws information from the controller on site and displays current device values and historical graphs. The server is designed to be as user friendly as possible. The graphs can be adapted and manipulated, giving you the freedom to display information however you want. We have designed the Remote Access to have a two way interface. This means that not only can you view nearly every setting on the server that can be seen on the analyser itself, but you can also alter these settings too. Logging on to our Remote Access server really is like being stood in front of the controller itself!The best thing about our Remote Access service is it’s free! There is just the initial cost of equipment required to access the server, but no ongoing service cost after that. Here at Pi, we know from experience that one size does not fit all. Each site has its own connectivity issues and access restrictions. That is why we have designed our Remote Access to be accessible through a variety of different options, which are outlined below. If you are unsure about anything, don’t hesitate to get in touch, we will be happy to help.
