A pump controller which helps to provide extremely accurate dosing in applications requiring automated and proportional pumping, is now available through dosing and mixing specialists Milton Roy UK. The Varipulse controller is a competitively priced package which ...
...has been developed for use with Milton Roy GA and GM series dosing pumps, typically used for water, wastewater, surface and chemical treatment applications.
Building on the success of the original Varipulse controller, this new interactive device enables proportional control of pump flow rate in relation to digital or analogue signals and features a simple and clear LCD screen and 3 additional operating modes.
The controller operation is based upon vector voltage control electronics which compensate for variations in power supply voltage by adjusting and generating a voltage and frequency to control a three-phase motor through a series of starts, without compromising performance over the entire operating range.
Two versions are available. A simple frequency variation version, or one with seven interactive operating modes with LCD screen, manual stroke speed, proportional stroke speed by analog signal, manual speed frequency or automatic control by analog signal, external trigger by pulse, batch or calibration.
