A cleaning system for an agricultural sprayer may include a sprayer boom, a plurality of nozzle assemblies provided in association with the sprayer boom and configured to dispense an agricultural product during a spraying operation of the agricultural sprayer, a first cleaning fluid tank configured to hold a first cleaning fluid, and a nozzle assembly fluid circuit fluidly coupling the plurality of nozzle assemblies and the first cleaning fluid tank. Moreover, the cleaning system may include a cleaning station supported on the sprayer boom, the cleaning station comprising a first valve. Additionally, the cleaning system may include a first cleaning fluid circuit fluidly coupling the first valve and the first cleaning fluid tank. The first valve is configured to supply the first cleaning fluid therethrough when the first valve is in an open position.

A sensor assembly for measuring a level of a liquid includes a measuring section through which a measuring current runs during operation of the sensor assembly and a temperature compensation section. The temperature compensation section compensates a temperature dependent variation of the measuring current within a predetermined operational temperature range.

An automatic liquid density measurement device includes a receptacle configured to contain the liquid, a float configured to be submerged in the liquid when it is contained in the receptacle, and an electronic system. The electronic system includes a first electromagnetic sensor configured to make a reference measurement relative to the electrical properties of the liquid, a second electromagnetic sensor configured to make a measurement of the volume of the liquid displaced when the float is submerged in the liquid, and an electronic circuit coupled with said first and second electromagnetic sensors to determine the density of the liquid based on the measurement of the physical properties of the liquid and the measurement of the volume of the liquid displaced.

A product system for an agricultural sprayer can include a product tank configured to store a first volume of an agricultural product. A second volume of the agricultural product can be positioned within a flow assembly after the fill mode. A reclaim system can be configured to provide the agricultural product within the flow assembly to the product tank. A computing system can be communicatively coupled with the reclaim system and configured to determine an open volume of the product tank based on data captured by the tank sensor and activate a reclaim mode of the reclaim system to move the second volume of the agricultural product from the flow assembly to the product tank when the open volume can be greater than the second volume of the agricultural product.

A system and method for efficiently measuring the fluid level in a container having a non-uniform cross sectional area is described. The measuring device may be immersed in the fluid and have a float slidable along a structure having the capability to sense an aspect of the location of the float. Since the accuracy requirements in measuring the fluid level may be more important for the higher levels and the lower levels than the intermediate quantities, the sensor may likewise be configured to provide more accurate measurements near the upper and lower fill levels. The position of a float may be determined by capacitive optical or magnetic sensing techniques and the sensed position translated into engineering units for output by a calibration table.

A septic system level detection system includes a means to detect a fluid level within a septic system that indicates a failure or possible impending failure of a septic system and means to communicate an alert of this indication via electronic messaging media. A digitized record of information related to the identified septic system is stored in a database. Upon receipt of a septic system failure alert, at least a portion of the digitized record of information is transmitted via an electronic communications system network, i.e., a network comprising a telephony network and/or the Internet, to a predesignated address of the network.

A pressure transducer assembly comprises a pressure transducer, a cable, an expandable member, and a vented connector. The cable includes a proximal end, a distal end, and a vent tube. The proximal end is operatively connected to the pressure transducer. The expandable member is operatively connected to the vent tube proximate the distal end. The vented connector is operatively connected to the distal end, and the vented connector is configured and arranged to allow exposure of the vent tube to atmospheric conditions when in a disconnected configuration and to prevent exposure of the vent tube to atmospheric conditions when in a connected configuration. The expandable member accommodates changes in air pressure within the vent tube when the vented connector is in the connected configuration.
