A hand-manipulable electrostatic spray gun is disclosed which is one requiring no electric cable attached to it. Within the hand-manipulable spray gun an air turbine is driven at high speed in the order of 60,000 rpm and drives directly an alternator to generate an alternating voltage in the order of 50 volts at about 1000 Hz. The output of this alternator is supplied to a step-up transformer to achieve a secondary voltage in the order of 2500 volts. From here, it is supplied to a long chain series voltage multiplier to increase the voltage thereof to one in the order of 55-80 kilovolts. The combination of a relatively small transformer and small capacitance establishes a direct voltage output from the voltage multiplier which has an alternating voltage ripple in excess of fifteen percent. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Electrostatic spray gun apparatus

A liquid gauge for measuring liquid level in a container having a differential pressure transducer positioned in the liquid. The transducer has a first port exposed to liquid adjacent the bottom of the container and a second port in communication with the environment above the liquid. The gauge may include a water level detector and a temperature measuring transducer. The gauge will measure the hydrostatic pressure of the liquid which is a determination of the liquid level and/or volume.
