The SDI 2200 Automatic, On Line, Silt Density Index Monitoring System is a unique on-line control system, designed for continuous, unattended operation in desalination and other water treatment plants. In many applications the automatic system is utilized in monitoring water pretreatment and in a reverse osmoses environment.

The SDI 2200 is used in critical water quality applications, where precise control is essential for safe and economic operations. It replaces the manual, error prone, conventional procedure with an automatic, precise and infallible routine. The Analyzer is a complete self-contained system meant for unattended operation with extensive reliability and with advanced fault analysis and warning. The operational display panel provides the operator with interface and on-line control to the Analyzer control functions.

The rugged, spray proof (IP 53) wall mountable Analyzer performs all the below steps that are required for quality water testing results: Flushes pipes prior to measurement, Controls water pressure, Measures flow rate, Replaces filter, Drains the water and cleans the system at the end of each cycle, Programmability of the measurement protocol, Monitors executed program, Data logging in digital memory, Real time SDI and status display, Programmable alarm on over-limit levels, Self-test and fault conditions alarm, and Optional dry contact and analog signals for remote control and monitoring.

There are four possible input channels for the SDI-2200 driven analyzers categorized as follows:

1-Channel Analyzer:  SDI-2201 2-Channel Analyzer:  SDI-2202

3-Channel Analyzer:  SDI-2203 4-Channel Analyzer:  SDI-2204
