The MicroVision conductivity cooling tower controller from Pulsafeeder comes standard with Toroidal Sensor Technology, which reduces the potential for fouling, and there is no need to recalibrate. It is a microprocessor-based controller with selectable timer and dual biocide control. Designed specifically for cooling tower applications, it comes standard with the functions needed to accurately monitor and control cooling tower water, such as a toroidal conductivity sensor, large graphical display with large, easy-to-read font, statistics screen with relay runtime, flow switch input, three drum level inputs, 4-20 mA isolated analog output, dry contact alarm output, battery backup, selectable timer, dry contact/hall effect water meter input, and the bleed output supports solenoid valve or motorized ball valve. 800/333-6677; www.pulsatron.com.
