ABSTRACT:
For use in preparing cement to cement a well, a cement metering system is set forth. The preferred and illustrated embodiment incorporates flow meters measuring water delivered to a cement jet mixer for cement and water into a slurry. A downstream density meter is included. A second water line dilutes the slurry to adjust the density downwardly to the desired slurry density controlled by the control system. The control system includes a data formatting circuit connected to the various transducers which converts the data so that the density required for the slurry is obtained. As desired, the data can be totalled by integrating over a period of time and shown on the data display. Volume flow rate of the controlled density slurry and bulk volume of dry cement may be determined.
