Abstract: An apparatus for filtering touches and disturbances of a container comprises a processing unit (PU) and computer-readable storage devices storing machine instructions. The PU obtains and sums together sensor values for a first sampling time from electrodes affixed to the container. The PU determines a difference between the sum for the first sampling time and a sum for a second sampling time, which is compared to a threshold representative of a change in capacitance due to a touch on the container. The PU determines whether the touch on the container has occurred at the first sampling time based on the comparison. If a touch occurred, the PU continues to obtain additional sensor values for additional sampling times and determine whether a touch on the container has occurred at the additional sampling times, until determining no touch occurred. The PU determines liquid level for the container after determining no touch occurred.

Abstract: Systems and methods are provided for determining a content of a hydrocarbon or other compound, such as a C3 to C7 hydrocarbon, in a condensed steam sample. Cooled steam condensate can be flowed through a sample chamber including an inner overflow tube. When the flow stops, water can be drained from the sample chamber, and then the sample chamber can be opened to allow fluid communication with a vapor chamber above the sample chamber. This can allow hydrocarbons in the condensed steam (and/or other gas) to be transferred from the sample chamber into the vapor chamber. The vapor chamber can then be isolated from the sample chamber. At least a portion of the content of the vapor chamber can then be passed to a detection volume, such as the characterization cell for a gas chromatography system.
