Abstract
A fluid sampling 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;
- a flow valve, configured to close the measuring chamber after ingestion of a fluid sample;
- an inlet tube, coupled between the measuring chamber and the flow valve, configured to enable positioning of the flow valve at a specific location and depth;
- a pump, configured to:
- flush the measuring chamber at a first flow rate;
- and
- ingest a fluid sample at a second, lower flow rate;
- at least one sensor having an equilibration time greater than temporal variability of at least one fluid property of the fluid sample;
- a communications circuit configured to transmit sensor readings to a remote monitoring center;
- and
- a processor coupled to the pump, the at least one sensor, and the communications circuit, programmed to:
- perform a flushing cycle comprising forward and reverse flow patterns;
- ingest the fluid sample and seal the measuring chamber;
- and
- obtain measurements from the at least one sensor following equilibration.
A method for sampling a fluid, comprising:
- drawing a fluid sample into a sampling chamber through at least one controllable inlet;
- allowing the fluid sample to be measured by at least one sensor disposed in the sampling chamber;
- and
- controlling operation of the inlet, a pump, and the at least one sensor using a processor to enable the at least one sensor to:
- equilibrate following the drawing;
- and
- obtain at least one measurement of a property of the fluid sample.
