Abstract: An automatic flow measuring device is used in an industry where accuracy in dispensing of liquid is necessary. It is fully automatic in nature and is used with a PLC (programmable logic controller) to give the system intelligence and reporting capability. The automatic flow measuring device for measuring fluid flow includes an automatically operated valve, a tee connector operatively coupled to the automatically operated valve, an elongated member defining a measuring chamber coupled to the tee connector, at least a first fluid level sensor mounted on the elongated member at a first position thereon and a second fluid level sensor mounted on the elongated member at a second position thereon. The first and second sensors are preferably electronic and send signals to the PLC which opens and closes the automatically operated valve.

Abstract: A push-type collet and seat assembly has a push-type collet including an elongated cylindrical body having a rear end portion, a front end portion tapering inwardly towards a front end thereof, an opening extending longitudinally through the collet, and slots extending longitudinally through at least the front end portion in communication with the opening to divide the front end portion into separated compressible portions. A workpiece is inserted into the opening of the collet and extends forwardly of the compressible portions. A seat partially receives the collet therein so that, when the collet front end portion is forcibly wedged against the seat, the compressible portions are squeezed against the workpiece to fix the workpiece relative to the collet. A stop is disposed a predetermined distance forwardly of the seat and adapted to receive the workpiece front end so that, when the workpiece front end is forcibly wedged against the stop, the stop limits forward movement of the workpiece.
