Abstract
A rail vehicle includes a truck having wheels for engaging a railroad track, a bolster supported by the truck, and a tank supported by the bolster for storing a lading. A measurement system measures the level of the lading within the tank and includes gauges and a controller. The gauges are disposed at selected points on the bolster for sensing at least one of lateral and longitudinal localized displacement experienced by the bolster during motion of the rail vehicle. The controller calculates the level of the lading within the tank and compensates for changes in the level of the lading during motion of the rail vehicle in response to signals generated by the gauges.
Claims11
A method of automatic control of refuel equipment, comprising:
- determining that an interlock is actuated;
- actuating, via a controller, a pump relay for a first setpoint pump speed for maximum fuel flow rate;
- actuating, via the controller, the pump relay to change the pump speed to a second setpoint pump speed for an approach flow rate when the first setpoint is reached, wherein a strain gauge is used to determine when the first setpoint is reached;
- and
- halting pump operation when the second setpoint is reached, wherein the strain gauge is used to determine when the second setpoint is reached.
