Abstract
the device is provided for measuring an exact amount of fluid in a dispensing operation, the device being made easily portable and self-contained. The fluid motor has a device on it to measure the number of rotations of the motor and that number of rotations is translated through appropriate circuitry into a corresponding fluid volume. Initiation of the dispense cycle by means of manually opening a handle latches open a valve which stays open until the desired predetermined volume of fluid has been dispensed. At that point, a solenoid is energized with a brief electrical pulse which unlatches the valve and allows it to close quickly, thereby assuring that an extremely accurate amount of fluid has been dispensed.
