If you choose the right electronic water level control system, it will be safe yet cost less to operate than a mechanical float system over the lifespan of the cooling tower.

As an illustration, if you replace the mechanical float in a cooling tower every three years, at a cost of approximately $300 each, plus installation, then over 25 years, you will have paid a total of $2,400 for eight floats. Compare this to a total of less than $500 for a simple $20 replaceable component part every 10 years plus the cost of rebuilding the solenoid valve every five years at a cost of $75 each. As this example illustrates, the right electronic water level control system can save you thousands of dollars versus mechanical floats over the expected life span of the cooling tower.
