digital readout
The readout of an instrument by a direct, numerical reading of the measured value or variable. Also see analog readout.
lineal (LIN-e-ul)

variable frequency drive (VFD)
An electronic device that is used to vary the frequency of an electric current applied to a motor. While the motor is not running, it is first connected to a low-frequency source; then, the frequency is incresaed gradually until the motor and pump (or other driven machine) are operating at the desired speed. This allows operators to precisely control the rotational speed of the motor.
manhole infiltration
Groundwaters seeping or leaking into a manhole structure.
