4-20 mA Controlled Pumps

Many transmitters and other water treatment equipment can provide a 4-20mA analog signal that can be used to control output of a metering pump. Pulsatron E Plus Series feeders have optional 4-20mA input control along with manual controls (100:1 turndown ratio). Fully scalable 4-20mA input controls are standard on the microprocessor controlled Pulsatron MP Series feeders which also have more precise 1000:1 turndown ratio manual controls.
