Abstract
An apparatus and method for fluid sampling is provided. The apparatus includes: a sampling chamber, configured to receive a fluid sample; at least one controllable inlet fluidically coupled to the sampling chamber; a pump, configured to draw fluid through the inlet and into the sampling chamber; at least one sensor, disposed to measure at least one property of the fluid sample within the sampling chamber; and a processor, configured to control operation of the inlet, the pump, and the at least one sensor to obtain a measurement of the fluid sample following equilibration of the fluid sample.
Claims20
A fluid sampling apparatus, comprising:
- a sampling chamber, configured to receive a fluid sample;
- at least one controllable inlet fluidically coupled to the sampling chamber;
- a pump, configured to draw fluid through the inlet and into the sampling chamber;
- at least one sensor, disposed to measure at least one property of the fluid sample within the sampling chamber;
- and
- a processor, configured to control operation of the inlet, the pump, and the at least one sensor to obtain a measurement of the fluid sample following equilibration of the fluid sample.
A fluid sampling chamber for in-situ measurement of heterogeneous aquatic fluids, comprising:
- a sealed measuring chamber comprising a flexible bladder, configured to define an internal sampling volume;
- at least one controllable sampling inlet coupled to the flexible bladder;
- a pump, configured to flush the flexible bladder and draw a fluid sample into the internal sampling volume;
- a mixer, positioned to homogenize the fluid sample within the internal sampling volume;
- at least one sensor having an equilibration time greater than temporal variability of at least one fluid property external to the chamber;
- a cleaner;
- at least one unidirectional flow valve configured to seal the internal sampling volume during equilibration;
- and
- a processor configured to:
- perform a flushing cycle prior to sampling;
- fill the internal sampling volume with the fluid sample;
- activate the mixer to homogenize the fluid sample;
- allow the at least one sensor to equilibrate while the internal sampling volume is sealed;
- obtain at least one measurement from the at least one sensor;
- and
- activate the cleaner between sampling operations.
A method for sampling a fluid, comprising:
- drawing a fluid sample into a sampling chamber through at least one controllable inlet;
- allowing at least one sensor disposed in the sampling chamber to measure at least one property of the fluid sample;
- and
- controlling operation of the inlet, a pump, and the at least one sensor using a processor to obtain the measurement.
