Abstract

An anti-fouling submersible liquid sensor (100) is provided according to the invention. The anti-fouling submersible liquid sensor (100) includes a measurement chamber (102) including one or more liquid measurement sensors (121) and at least one chamber aperture (104), at least one gate (107), a gate actuator (128) configured to selectively move the at least one gate (107) between open and closed positions with regard to the at least one chamber aperture (104), and a radiation source (124) configured to inactivate at least a portion of a liquid sample in the measurement chamber (102). The anti-fouling submersible liquid sensor (100) is configured to admit the liquid sample into the measurement chamber (102), perform one or more measurements on the liquid sample, substantially inactivate biological material within the liquid sample with radiation from the radiation source (124), and hold the inactivated liquid sample until a next sample time.
