Abstract: Apparatus to mount process control devices to actuators are described. An example includes a mounting plate having a first side to receive the process control device and a second side opposite the first side, where the second side includes a first clamping finger extending away from the second side and configured to engage a first edge of an actuator yoke. The example apparatus also includes an elongated clamp arm having second and third clamping fingers adjacent respective ends of the elongated clamp arm, where each of the second and third clamping fingers is configured to engage a second edge of the actuator yoke opposite the first edge, and where the elongated clamp arm is slidably coupled to the mounting plate. Additionally, the example apparatus includes a fastener adjustable to cause the elongated clamp arm and the mounting plate to slide toward each other so that the first, second and third clamping fingers engage the respective edges of the yoke to fix the mounting plate relative to the yoke.

Abstract: Example methods and apparatus for level loop control are disclosed. A disclosed example method includes determining via a sensor a first pressure of a liquid in a tank, determining via a turbine flow meter a second pressure of the liquid in the tank, determining if the first pressure is within a specified range of deviation from the second pressure to determine an operational state of the turbine flow meter, and transmitting a diagnostic message indicating that the turbine flow meter needs to be serviced based on the state of the turbine flow meter.

Abstract: Apparatuses to control a fluid flow characteristic of fluid regulator bypass valves are described. An example apparatus includes an insert having a body sized to be inserted in a passage of a bypass valve. The body includes an opening to fluidly couple a bore of the body to an outer surface of the body. The opening being shaped to produce a predetermined flow characteristic in response to at least a portion of a restrictor of the bypass valve moving relative to the opening to vary a fluid flow through the opening and the bypass valve.
