10. RODI Systems Product Examples
AquaLynx® RO Controllers
RO Performance MonitorTM
EZ SDITM Silt Density Index Monitors
DataFlex RemoteTM
RODI Systems’ standard products were developed specifically for membrane-based water treatment applications.

11. AquaLynx® Model 350 One Conductivity Input One Temperature Input
Two Flow Inputs
Six Discrete Inputs
Six Relay Outputs
The AquaLynx Model 350 is the least expensive the of AquaLynx RO controller line. It is suitable for small to medium sized commercial and industrial RO systems.

12. AquaLynx® Model 250 Two Conductivity Inputs Two Temperature Inputs
Two Flow Inputs
Six Discrete Inputs
Six Relay Outputs
Data Logging and Remote Accessibility
The AquaLynx Model 250 is the mid-level RO controller from RODI Systems. It is suitable for large commercial systems and industrial systems.

13. AquaLynx® Model 100 Two Conductivity Inputs Two Temperature Inputs
Three Flow Inputs
Four Analog (4-20 mA) Inputs
PLC or Modbus Interface
Data Logging and Remote Access
Acts as PLC Interface
The AquaLynx Model 100 is unique in that it can communicate directly with a PLC via a serial connection. Since it is designed to be used with a PLC, it has no discrete inputs and no relay outputs.

14. DataFlex RemoteTM Remote Monitoring System
Four Analog Inputs
Two Flow Inputs
Four Discrete Inputs
Two Relay Outputs
Optional pH, ORP, or Conductivity Inputs
Data Logging
Remote Monitoring via Modem
The DataFlex Remote was designed for monitoring remote treatment systems. It is used extensively for monitoring small service deionization systems. The user can dial into the DataFlex remotely with RODI’s AquaGraph software. The DataFlex can also dial out to RODI’s ALARM software to report alarm conditions.

15. RO Performance MonitorTM
Single Device Performs All Monitoring Functions
Real-Time Data Normalization
Internal Sensors
Alarm Logging
Data Logging
The RO Performance Monitor is a single instrument that performs all monitoring functions for an RO unit. It monitors all pressures, flows, conductivities, and temperatures necessary to calculate RO performance. It does all of the normalization calculations in real time and logs data to internal memory. All sensors (with the exception of flow) are internal to the Monitor and are connected to the process piping by means of nylon tubing. This greatly simplifies installation of the Monitor.

16. RODI Systems’ Software
AquaGraphTM – Provides remote access to AquaLynx®, DataFlex, and RO Performance MonitorTM; also allows data downloading and graphing
ALARM – Provides 24/7 alarm monitoring for remote DataFlex installations
RODI provides two software packages for use with its products. The AquaGraph is used to remotely access modem-equipped AquaLynx units (Models 250 and 100 only), view system performance in real time, down load logged data, and graph the data. The ALARM software is used to continuously monitor alarm notification from remote DataFlex units.

17. AquaGraphTM Software
With AquaGraph, the user can dial into a remote AquaLynx (Models 250 and 100), DataFlex unit, or RO Performance Monitor and view the system in real time. A reproduction of the instrument keypad and display appears on the user’s PC screen and by using the cursor and mouse, the user can “press” the keys to operate the monitor just as he would if at the monitor itself. AquaGraph allows the user to down load logged data, save the data, and prepare custom graphs with any of the downloaded data. These graphs may be exported to other documents for report preparation.
Provides real-time reproduction of AquaLynx® instrument face on PC screen
Allows custom graphs to be prepared from downloaded logged data

18. ALARM Software
RODI’s ALARM software is designed to run on a dedicated PC at a central location to continuously monitor incoming calls from remote DataFlex units for alarm reporting. When it receives a call from a DataFlex unit, the ALARM software logs the alarm on the host PC and can relay the alarm notification via pager, fax, or .

19. EZ SDITM Automatic Silt Density Index Monitor
Automated Version of ASTM Method for RO Feed Water
Determines RO Fouling Tendency from Suspended Particles by Means of Filter Plugging
Very Sensitive to Particle Size and Concentration
The silt density index (SDI) test is still the most highly recognized test procedure for determining the fouling tendency of RO feed water. The EZ SDI monitors from RODI are automatic testing systems that perform the ASTM test.
