In one aspect, a system for monitoring a level of hydraulic fluid in an agricultural sprayer includes a drive system, a hydraulic fluid system, and a fill level sensor. The system also includes a computing system communicatively coupled to both the drive system and the fill level sensor. The computing system is configured to monitor the level of hydraulic fluid within the hydraulic fluid reservoir based on data received from the fill level sensor. The computing system is further configured to detect a leak condition in the hydraulic fluid system based at least in part on the monitored level of the hydraulic fluid within the hydraulic fluid reservoir and control an operation of the drive system to reduce the ground speed of the agricultural sprayer in response to detecting the leak condition.

A cap for a fluid sensor is provided. The cap comprises a cap input port including a first toolless connector configured to removably couple to a cable; and a cap output port including a second toolless connector configured to removably couple to a cable. The cap may further comprise an interface circuit including a circuit input port, a circuit output port, and a sensor port configured to couple to the fluid sensor. The first toolless connector may be configured to removably couple the circuit input port to a cable and the second toolless connector may be configured to removably couple the circuit output port to a cable. The circuit will automatically sequence the signals on the cable, so standard one-to-one wired cables can be used.

An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.

An automatic fill system includes a tank, a transfer hose, and a valve assembly. The valve assembly has a first end having an outlet orifice configured to be received within the tank. The valve assembly also includes a second end configured to be connected in fluid communication with the transfer hose with the second end having an inlet orifice. The valve assembly also includes at least one fluid passageway between the inlet orifice and the outlet orifice, and a check valve coupled to a spring and a seal. The seal is configured to be slidably moveable within a piston chamber. The valve assembly further includes a heating element located within a heating element chamber and configured to heat the valve assembly. Finally, the valve assembly includes a jet level sensor with a sensor inlet and a sensor outlet. The jet level sensor is in fluid communication with the piston chamber.

A testable overfill prevention valve (TOPV) for a liquid storage container. The TOPV allows an individual to readily verify the operability of the TOPV. Preferably, a test member of directly contacts a portion of a latch to release a flow control member so that the flow control member can move from an open position to a closed position wherein in the closed position liquid is generally prevented from flowing out the TOPV. The test member preferably directly contacts the flow control member to move the control member to an intermediate position between open and closed positions allowing an individual looking down into the TOPV to see that the flow control member has moved sufficiently to confirm operability of the TOPV. Preferably, the test member is spring biased to a non-testing position and the entire test member is disposed in the housing of the TOPV when in a testing position.

A mobile liquid transferring system comprising a first articulating fluid conduit configured to couple to a first tank, a pump comprising a pump inlet in fluid communication with the first articulating fluid conduit, a flow meter comprising a first pickoff for a first liquid of a first viscosity and a second pickoff for a second liquid of a second viscosity, a meter register configured to control flow of the first liquid and the second liquid in accordance with one or more loading parameters and one or more liquid parameters, a flow control valve in fluid communication with the flow meter and configured to alter flow of at least one of the first liquid and the second liquid in response to a communication from the load rack controller, and a second articulating fluid conduit in fluid communication with the flow control valve and configured to couple to a second tank.

According to the embodiments described herein, a bottom loading valve can include a drive member, a valve body, and a piston. The drive member can be operably coupled to a motor. The valve body can define a fluid passageway and one or more lateral openings. The drive member can be positioned within the fluid passageway. The one or more lateral openings can be offset laterally from the drive member. The piston can be engaged with the drive member. The piston can move throughout an open position and a closed position, as the drive member communicates force from the motor. When the piston is in the closed position, the piston can fully obstruct the one or more lateral openings from the fluid passageway.

A system for delivering fuel to an equipment fuel tank. The system includes a remote fuel storage tank and a valve assembly coupleable to the equipment fuel tank. The system includes a fuel supply line extending between the remote fuel storage tank and the valve assembly and a pneumatic valve disposed in the fuel supply line. The pneumatic valve can prevent flow of fuel into the fuel supply line or can enable flow of fuel into the fuel supply line. The valve assembly includes pressure tubes to detect changes in fuel level inside the equipment fuel tank. A switch actuates the pneumatic valve to prevent the flow of fluid in response to an overfilled position; and actuates the pneumatic valve to enable the flow of fluid in response to an underfilled position.

A fuel delivery system and method for reducing the likelihood that a fuel tank of equipment at a well site during fracturing of a well will run out of fuel. A fuel source has plural fuel outlets, a hose on each fuel outlet of the plural fuel outlets, each hose being connected to a fuel cap on a respective one of the fuel tanks for delivery of fuel to the fuel tank. At least a manually controlled valve at each fuel outlet controls fluid flow through the hose at the respective fuel outlet.
