Running variable frequency drives (VFDs), and some of the most sophisticated programmable logic controllers (PLCs) available at the time, Electromate made monochrome touchscreen control panels. The Pump Station Director panels were ahead of their time. The panels measured and displayed information to extreme detail and measured every conceivable variable. The engineers and programmers working for Electromate wrote a software called “Shazam” designed to determine the most economical conditions for the panel to run. Shazam prolonged equipment life and saved site owner capital with attenuated energy costs.
Because of the obviously large sticker price, not many Pump Station Directors were manufactured. Many of these panels are still in service and have paid their investment back in spades with energy savings. Keep in mind, this was in the 1980s, a lot of these things were not on peoples’ minds for a few more decades.
