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.

Cement supply control systems and methods

The disclosure provides a system comprising one or more supply tanks; a central cement mixing unit; a support unit comprising a compressor and a power supply; a first valve disposed upstream of each of the one or more supply tanks; a second valve disposed downstream of each of the one or more supply tanks; a controller disposed at the central cement mixing unit; and a secondary controller disposed at each of the one or more supply tanks; wherein the one or more supply tanks are coupled to the central cement mixing unit, wherein the compressor is coupled to each of the one or more supply tanks, wherein the power supply is coupled to the compressor and to each of the one or more supply tanks, wherein the controller is communicatively coupled to each of the secondary controllers and to the support unit.

Remote control bulk material monitoring and delivery system

The disclosure provides a method of monitoring a flow rate of a liquid additive comprising measuring the flow rate of the liquid additive with a flow meter; transmitting the measurements of the flow rate to a controller; transmitting, from a variable frequency drive (VFD), measurements of a rotational speed of a motor to the controller, wherein the VFD is coupled to the motor; transmitting measurements from a level sensor to the controller; determining whether the flow rate of the liquid additive is a non-zero rate; utilizing the measurements transmitted to the controller as feedback to compare against a designated set point; calculating an error between the feedback and the designated set point to calculate an updated output; and transmitting the updated output to the VFD to change the flow rate of the liquid additive.

Additive control method utilizing smart redundant feedback

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.

Engine and transmission notification system using a J1939 data link interface

Various embodiments include a variable frequency drive motor control apparatus. The apparatus includes a main controller having a first interface. A motor controller is coupled to and controls an electric motor, the motor controller further coupled to the main controller. A network switch is coupled to the main controller, the motor controller, and a remote controller over respective digital connections. The remote controller has a second interface. The network switches data between the first interface, the second interface, and the motor controller. A network coupler is coupled between a variable frequency drive controller and the motor controller.
