Pulsatron Plus Series CW Metering Pump
The PULSAtron Plus Series CW Metering Pump was designed to control conductivity and feed inhibitor in an open-air cooling tower. Chemical feed is initiated and controlled by input from a water meter. The Series CW combines everything you need to control conductivity and feed inhibit into one unique, compact package to create a simple and cost effective metering control system.
The Series CW Metering Pump includes a solenoid actuated metering pump, conductivity sensor, bleed relay and a dry contact input for water meter control. At set-up, the operator sets the conductivity set point, differential (or dead-band), the pump stroke frequency and run time. When conductivity reaches the set point, the system activates the bleed relay.
As make-up water passes through the water meter, it generates a series of pulses based on volume of flow. The pump counts the pulses until the total reaches the Count set point. The pump runs at the frequency and run-time specified at set-up and the count is reset.
The pump features an easy to program user interface. Simply press the universally recognized symbol key identifying the function you wish to adjust and change the value with the up or down arrow key.
The user determines the amount of chemical feed based on the volume of make-up water. Programmable run time, stroke frequency and count set point combine to provide precise control over the amount of chemical used.
Series CW Metering Pump is one unique package. All control functions are integrated into the pump eliminating the expense of purchasing and installing a separate controller.
