Until we as a species develop X-ray vision, then, the best way to monitor your building's water-flow for optimum efficiency is to use a pump control like this industrial-strength from ITT Monitoring — the PumpSmart PS200 v.5. Besides looking snazzy, it combines process control and pump protection, and comes with pre-programmed pressure, flow and level control, among other applications. Its many other features include a Pump Wear Monitor," which regularly checks your pump's performance. Our favorite feature: Flow Economy, which measures how much fluid you pump moves with one kiloWatt of energy, similar to the fuel-economy ratings of cars.
The PS200 is a modular component of a whole blamed PumpSmart system, but it also works on its own. No suggested retail price is available ; there's a "Get a Price Quote" page at the local New York City-area distributor, below.
