W3 Series Fertigation System

W3 Series Fertigation System

The W3-Series consists of one metering pump available in six different sizes, driven by an integral proportional control system. This system is designed to be furnished with a Data Industrial model 220 flow sensor, or using the on board opto-isolator, can be slaved off of the sensor on a package pump station. The pump is motor driven and controlled using the latest VFD technology. This system was created to be a simple, economical solution for reliable proportional injection. In the base model, the proportional rate is set simply by adjusting the knobs on the pump. If more features are desired, you can download the optional Watcher™ software package, and access the onboard computer with a Windows based laptop. With the Watcher software, you have access to many of the features of our larger systems, such as time and date settings, direct PPM rate setting, water and product usage logs, and several others. The system is ideal for grow-in applications and for those who want a simple yet state-of-the-art system on a limited budget.
