calibration tank"(Also called rating tank.) A tank of still water in which a current meter is moved at a known velocity for calibration.

Calibration: The process of using historical data to estimate parameters in a hydrologic forecast technique such as Sacramento Soil Moisture Accounting Model (SACSMA), routings, and unit hydrographs.
Calibration Act of comparing an instrument's measuring accuracy to a known standard.
Calorie The amount of heat needed to raise the temperature of one gram of water at 15° centigrade one degree centigrade. Compare with British Thermal Unit.
Calibration and data quality centres
These have the job of ensuring that all data produced by the system measure up to international standards.
Calibration The process whereby a position on the scale of an instrument is identified with the magnitude of the signal (or input force) actuating the instrument.
SPENESNESDIS Satellite Precipitation EstimatesSphere CalibrationReflectivity calibration of a radar by pointing the dish at a metal sphere of (theoretically) known reflectivity. The sphere is often tethered to a balloon.
standard - An established unit of measure, reference instrument, or method appropriate for the calibration of other instruments.
These are quite convenient, in that they can be placed on a fence post or any other structure without too much of a problem. The gauge calibration marks are on it, and the rainfall amounts are read directly off the gauge.
Runway Visual Range (RVR)- An instrumentally-derived value, based on standard calibrations, that represents the horizontal distance a pilot may see down the runway from the approach end.
Standard atmosphere: a hypothetical vertical distribution of temperature, pressure and density which, by international consent, is taken to be representative of the atmosphere for purposes of pressure altimeter calibrations, ...
This notation is used frequently with error analysis. In that context, it is the square root of the arithmetic mean of the squares of the deviations of the individual calibration points from the theoretical or ideal response.
dropped in large quantities from aircraft or balloons in order to confuse enemy radar. Chaff typically produces a radar echo which closely resembles precipitation. Chaff drops are conducted by some military installations for testing and calibration ...
Chaff typically produces a radar echo which closely resembles precipitation. Chaff drops once were conducted by the military in order to confuse enemy radar, but now are conducted mainly for radar testing and calibration purposes.
His invention quickly became popular in the scientific community and was adopted as the standard for wind speed measurements in America and several European countries. The mechanical nature of the instrument required frequent calibration and ...
