Glossary
accuracy
degree of conformity of a measure to a standard or a true value.
algorithm
a prescribed set of well-defined rules or processes for the solution of a problem in a finite
number of steps.
ambient temperature
the temperature of the surrounding air that comes in contact with the enclosure of the device.
antenna
an aerial which sends out and receives a signal in a specific direction. There are four basic
types of antenna in radar level measurement, horn, parabolic, rod, and waveguide.
Auto false-echo suppression
a technique used to adjust the level of a TVT to avoid the reading of false echoes. (See
TVT.)
Auto false-echo suppression distance
defines the endpoint of the learned TVT distance. This is used in conjunction with auto false
echo suppression.
beam angle
the angle diametrically subtended by the on-half power limits (-3 dB) of the microwave beam.
blanking
a blind zone extending away from the reference point plus any additional shield length. The
device is programmed to ignore this zone.
capacitance
the property of a system of conductors and dielectrics that permits the storage of electricity
when potential differences exist between the conductors. Its value is expressed as the ratio
of a quantity of electricity to a potential difference, and the unit is a Farad.
