Principle:
The operating principle of ultrasonic level instrument is that
high-frequency ultrasound pulses transmitted by the transducer
(probe) are reflected when meeting the dielectric surface to be
measured, and part of the reflected echoes are received by the same
transducer and converted into electrical signals. An ultrasonic
pulse propagates at the speed of sound, and the time interval of
transmitting and receving ultrasound pulses is proportional to the
distance between the transducer and the dielectric surface to be
measured. The relation between this distance value S, the speed of
sound C and the transmission time T can be expressed using the
formula: S = CxT/2.
The transmitted ultrasonic pulses have a certain width that result
in overlap of the reflected waves within a small area closer to the
transducer with the transmitted waves, so it is impossible to
identify them and measure its distance value. This area is called
the blind zone. The size of blind zone is relates to the model of
ultrasonic level instrument.
Feature:
With advanced microprocessor and unique EchoDiscovery echo
processing technology, the radar level instrument can be applied
to various complex working conditions.
The “Virtual Echo Learning” function enables the instrument to
correctly identify true echo in the working conditions where
there are multiple virtual echoes to obtain correct
measurements.
The transducer has a built-in temperature sensor which can
provide temperature compensation for the measured values.
With the best patented technology of acoustic matching, the
ultrasonic transducer can radiate its transmitting power more
effectively and improve signal intensity to achieve accurate
measurements.
