1. INTRODUCTION
The Pulsafeeder ABC Controllers are used to control total dissolved solids
(TDS) in steam boiler systems, in terms of electrical conductivity measured in
microsiemens per cm (µS/cm). They are designed using the latest technology
with plug-in circuit boards.
The units are very accurate and easy to use. This simplified design provides
automated control at an economic cost.
The ABC Series comes standard with connections for AC power and blow
down activation.
