Description

The Aqua Purometer IG Water Monitor Indicator and Control System is used to monitor the purity of water by means of conductance measurements. It may be installed in water tanks or piping systems and can be used to monitor a great variety of water treatment such as distillation plants.

Meter values reflecting water purity level are continuously indicated on the panel meter. The scale on the panel meter may be changed to indicate chemical content, or other special option. An adjustable limit of allowable impurity is included in the electronic monitor circuit (alarm set point). The alarm set point is set by the operator to the desired level. If the water impurity level rises above this preset limit, the controller relay in the monitor circuit is de-energized, causing the ALARM indicator on the panel to light and/or a bell (where included) to sound, and all relay contact to switch state. A dump valve may be activated in alarm.
