Abstract: A method is provided for monitoring a chemical agent concentration in a chemical solution stored in a tank of a system of a motor vehicle. The system includes a pump driven by a motor where the pressure of the pump is controlled by a controller. The method includes measuring a plurality of values characteristic of the energy transmitted by the motor to the pump for a corresponding plurality of pump pressure values; determining at least one parameter of a relationship between the energy transmitted by the motor to the pump and applied pump pressure values from the plurality of measured values and the corresponding plurality of pump pressure value; and comparing the at least one parameter to predetermined reference parameters.

Abstract: A vehicular liquid containment system including a tank, a pump arranged to pump a liquid from the tank to a vehicular system via a feed line, a pressure sensor arranged to detect a pressure in a vapor dome inside the tank, and a sprayer arranged within a branch of the feed line, the outlet of the sprayer being arranged inside the tank.

Abstract: A method for monitoring urea concentration and quality in a urea solution stored in a tank of an SCR system. The system comprising a pump driven by a motor and the pressure of which is controlled by a controller. The method comprises the steps of:—measuring a parameter value characteristic of the energy transmitted by the motor to the pump;—determining a urea concentration value based upon the parameter value characteristic of the energy transmitted by the motor to the pump.

Abstract: The present apparatus is a method and system for treating and drying the surface of an object. According to the described method, with a wet object positioned in a vessel, a drying vapor is introduced into the vessel. The drying vapor condenses on the surface of the object and reduces the surface tension of the residual process fluid, causing the residual process fluid to flow off of the surface. In one embodiment, wet processing of the object and a subsequent evacuation of process fluid is carried out in the vessel prior to introduction of the drying vapor.

Abstract: Described herein is a chemical injection system and method utilizing a chemical storage vessel coupled to a bulk source of chemical and proportioned to contain a volume of chemical useful for multiple applications for which the chemical is to be utilized. A dispense vessel proportioned to contain a volume of chemical useful for a single application is fluidly coupled to the chemical storage vessel. A controller controls operation of a system of valves and sensors, which operate to fill the chemical storage vessel, and to precisely dispense the volume required for a single application from the storage vessel into the dispense vessel and then ultimately into the vessel in which the chemical is needed.
