Density sensing, solid state, pump switching system |
摘要 |
A pump control system incorporates one or more solid state level sensors as well as solid state pump control switches. Elimination of mechanical or electrode-mechanical parts by using ultrasonically based fluid level sensors as well as solid state switches for motor control enhances reliability and results in reduced power consumption and dissipation.
