Abstract: A system comprises a cement mixer, a supply tank to supply dry cement to the cement mixer, and a dry cement height sensor to measure the height of the dry cement in the cement supply tank. A valve controls the flow of dry cement to the cement supply tank based on the signals from the dry cement height sensor. Additional apparatus, methods, and systems are disclosed.

Abstract: A cementing system having an engine control module, a transmission control module, a computing device and a display. The engine control module communicatively coupled with a plurality of engine sensors. The transmission control module communicatively coupled with a plurality of transmission sensor. The computing device is communicatively coupled with the display and communicatively coupled, via at least one J1939 data link, with the engine control module and the transmission control module. The computing device is configured to receive data from at least one of an engine control module or a transmission control module, compare the received data to a list of stored codes and in response to the received data matching a stored code, causing the rendering of an alarm message associated with the matched code and/or a warning message associated with the matched code on the display.
