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.

The subject matter disclosed herein relates to fluid leakage detection. More particularly, subject matter relates to a device for detecting fluid leakage in a fluid drain pipe attached to a power transformer device. The device comprises fluid collection compartment attached to bottom of the fluid drain pipe and a fluid level switch is positioned in the fluid collection compartment to generate alarm signal to indicate fluid leakage.

A fuel storage system has a tank access chamber with improved monitoring, servicing and maintenance capabilities. In particular, the chamber includes a sump monitored by a liquid sensor whose proper function can be automatically checked remotely, e.g., via an electronic controller or remote manual operation. In cases where such a check indicates a need for physical inspection of the sump sensor, the present system provides for sensor removal and installation by service personnel from a location outside the tank access chamber. Thus, the present system facilitates regular inspection and routine or unplanned maintenance without the need for a person to physically enter the tank access chamber.

Data characterizing a fuel storage facility can be received from one or more of a plurality of sensors disposed in the fuel storage facility. A fuel leak prediction for the fuel storage facility can be determined by a server, based on the received data, and further based on at least one predictive model that predicts whether a fuel leak exists in the fuel storage facility. The fuel leak prediction can be provided by the server. Related apparatus, systems, methods, techniques, and articles are also described.

Exemplary embodiments disclosed herein are directed to systems and methods by which the contents of a container, such as the level of liquid nitrogen in one or more liquid nitrogen storage containers, can be locally and/or remotely monitored, and alerts can be generated if a leak is detected. The weight of the container, or a combination of the weight and the temperature of the container, may be monitored with respect to detecting a leak.

A tube infrastructure includes a first tube; a second tube that is coupled to the first tube; and a fluid tank that is disposed to surround a coupling region of the first tube and the second tube and is filled with a fluid to seal the coupling region, wherein the fluid tank allows negative pressure to be maintained inside the first tube and the second tube.

In a method and a corresponding system for identifying a fuel loss event, periodic measurements of a measured volume of fuel stored in a fuel tank (mobile or stationary) are received, and a measurement of a dispensed volume of fuel dispensed into the fuel tank is received from a fueling station. A total volume of fuel is determined equal to the sum of the dispensed volume of fuel and the measured volume of fuel last measured prior to receiving from a fueling station. A difference is determined between the total volume and the measured volume of fuel first measured subsequent to determining the total volume. If the difference exceeds a predetermined threshold indicating a fuel loss event, an alert is generated indicating that there is a fuel loss event.
