Monitor Technology

Next-Generation Real-Time Water Monitoring

Designed, developed and manufactured by Primodal Systems, the RSM30 is the next generation in real-time water monitoring equipment. Through a combination of state-of-the-art technology and custom software, the RSM30 is a flexible, user-friendly monitoring platform.


flexible enough to be deployed wherever you want it
STATE-OF-THE-ART – software framework that is second to none
USER-FRIENDLY – open-code structure allows users to customise output
 – logs and transmits real-time data AND analyzes the data in real-time.
– Analysis in real-time ensures that data issues and the resulting alarms are triggered quickly and efficiently, which will improve maintenance, minimize post-processing effort and maximizing the storage of ‘clean’ data.


The backbone of the RSM30 and Central Server is Primodal Systems’ own PrecisionNow software. This internally developed software package controls the storage and analysis of the measurement data as well as the flow of information to the central server.

PrecisionNow is the culmination of a multi-year development and testing effort. Field testing and feedback from industrial users of the units has resulted in a number of important refinements. On-going development is resulting in the continuous improvement in the user interface and software functionality.

Data Evaluation

The Value of PrecisionNow Software

The RSM system has been developed with Primodal Systems’ custom software (PrecisionNow) and has been designed specifically to address the need for more immediate and more advanced data evaluation in real-time.

Traditional data loggers simply log and transmit raw data without any automated evaluation. The PrecisionNow software that forms the backbone of the RSM system has been developed to overcome this deficiency in functionality.

In addition to built-in error checking (e.g. bound exceedance, sensor failure…) and simple data trending algorithms (e.g. moving averages, rates of change…), the Precision Now architecture provides an open-code, plug-in like system that gives users the option to develop and incorporate their own data evaluation modules. In addition to generalized data modules, users can develop site-specific algorithms to help identify control actions, maintenance requirements, water quality trends, system behaviour and data problems that are unique to the location and system under study. The ability for automated data analysis is limited only by the imagination of the user.

Easy-to-Deploy: Data Collection, Real-Time Analysis and Transmission

The RSM30 can operate alone or as part of a monitoring network.

Each RSM30 unit comes fully equipped with all the required components to operate in isolation, including the ability to store and visualise measurement and meta- data, as well as the communication tools to transmit the data to a central storage location.

No longer are data transmission issues a problem. The RSM30 has sufficient capacity to store years of data. Should communication with the RSM30 be interrupted, users can be assured that the full complement of data and data analysis algorithms is still operational thus ensuring that suspect data, and significant events will be properly logged when communication is restored.

Incorporation of several RSM30s into a monitoring network (that has been designed to monitor several different locations) couldn’t be easier as each RSM30 can communicate with other stations in the same network. Integration ensures the best possible data validation at the water’s edge in real-time.

Built to Last

The RSM30 is encased in a secure NEMA 4X rated fibreglass enclosure designed for a range of diverse environmental conditions. Suitable for year-round outdoor use, the RSM30 has been designed for rapid, ease-of-operation deployment.

The RSM30 is equipped with a number of user-friendly features including convenient handles to simplify its movement and portability. Climate control options can be included to mitigate extreme temperature fluctuations. Several power source options are also available including 110V (or 240V for European installations). Control of and communication with the RSM30 is accomplished by various means including GSM or satellite capability, making remote deployment a viable option.

Network Design

Primodal Experience at Work

Although the RSM30 can operate in isolation, the versatility of the RSM system and the PrecisionNow software is fully realised when used within a network of monitoring stations.

Whether the system under study is localized (a wastewater treatment plant) or distributed (a watershed), multiple RSM30s can be deployed at convenient and appropriate locations within that system. In a network design, the data from each RSM30 is transmitted to a central location (typically located at a head office, control room, …) where the data is logged for long-term storage.

At the same time, concurrent analyses can be performed to compare the data from different locations. This comparison of data could be as simple as a redundancy check or could be much more complicated. Depending on the system, model-based predictions could be compared to measured data to identify problems that would otherwise have gone unnoticed, or detected long after the event.

The goal is long term understanding of the system and the automated storage of ‘clean’ data while at the same time minimising the effort required to achieve that goal.

Central Server

Robust, Field-Tested, Reliable

The structure of the RSM system includes the provision for the transmission to and storage of data at a central location. Like the RSM30 at the water’s edge, the Central Server is equipped with a full complement of features including the ability to store and visualise measurement and meta- data. Data evaluation modules can be used to analyse the raw data for any number of purposes including the identification of sensor problems, alarm triggering, or prepping the data for long-term storage.

The Central Server is programmed to pull data from any and all RSM30s within the network at a time interval of the user’s choosing. This functionality enables the automated comparison of data from multiple locations in real-time and minimises the effort needed for post-processing by your staff.

Lease or Purchase

Recognising that the goals of a monitoring campaign can vary with each application, Primodal Systems offers clients the option to purchase a system outright or lease for short-term campaign needs.


When monitoring campaigns are shorter in duration (e.g. supplemental data acquisition for a wastewater treatment plant process upgrade and modelling study) leasing a system might provide the ideal solution.

Short-Term Leasing for consulting, planning and operational assessment is a popular and viable option for the RSM30, allowing consultants and facility managers the flexibility they need to acquire top-notch data evaluation quickly, with the proven accuracy they need to make informed decisions.

The short-term lease option is also a great way to try out the system without making an immediate, long-term commitment. This option also comes with an option to buy once the test phase is competed.


Clients with long-term goals or continuous monitoring needs might find it more cost-effective to purchase the system.
