Dry or low flow which can cause considerable damage and costly downtime to positive displacement & centrifugal pumps, can be prevented with the use of electronic flow monitors that can easily be incorporated into existing control systems.

The SI flow monitor is a rugged, reliable sensor with a titanium tip (the wet part), no moving parts that can stick or break in the process. The flow switch incorporates a microprocessor with two simple pushbuttons. This enables the sensor to be quickly and easily adjusted for an application. The LED bar graph display indicates the relative flow rate, the set-point value, and the output status. Using the SI's "teach" function, the sensor can learn the high and low flow rates.

these compact flow monitors are used for a number of applications in desalination plants, including:

pump dry running protection
product flow/no flow switching
