Highest Quality - Lowest CostPart of a range of controllers, the CRONOS® is the little brother of the CRIUS®. The CRONOS® is a high quality, low cost transmitter designed to give water treatment engineers everything that they need from a transmitter and nothing that they don’t. With no frills, costs can be kept to a minimum whilst optional communications packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP, 4-20mA analogue outputs, and relays for alarms and control. The CRONOS® has the capability to control up to two sensors of any type with appropriate analogue outputs and relays. Equipped with optional PID control, the CRONOS® is very able to control complex water treatment processes at a fraction of the cost of other controllers.
CRONOS® plus Sensor equals…
- Free Chlorine Analyser (HaloSense)
- Total Chlorine Monitor (HaloSense)
- Chlorine Dioxide Analyser (DioSense)
- Ozone Monitor (OzoSense)
- Dissolved Oxygen Meter OxySense
- Suspended Solids Monitor (SoliSense®)
- 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)
- Filter Monitor (FilterSense)
- Fluoride Monitor (FluoriSense)
- Pool and Spa Controller (AquaSense)
- External inputs
- Choose from Standard Configurations or ‘Build Your Own’
The CRONOS® is often used in applications where the remote access capability of the CRIUS® is not required. This doesn’t mean that a CRONOS® doesn’t have the capability of control! With full PID control, the CRONOS® is often used in application areas such as:
- Water Treatment
- Drinking Water
- Waste Water
- Pool and Spa Control
- Industrial Water
- Food and Drink
- Paper and Pulp

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.
