The unit type AS3050 or type AS3051 is universal applicable for automatic monitoring and control of cooling tower plants. The controller is equipped with a conductivity meter optional is a second conductivity meter and temperature meter. Also optional is a circuit board with two recorder outputs (0(4) – 20 mA). There are six possible stages : "Service", "Flush", "Low level", "Flush blocked" and "Shot dosing". Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.
