Principle of Operation
The SUMPI MR is an Ultrasonic Level Transmitter capable of measuring
liquid and solid applications up to a range of 30m. The Transducer
is fitted to the silo or tank and faced down towards the material
being measured. The microprocessor in the Transmitter fires an
electronic pulse which the Transducer converts to an acoustic
pulse.This pulse travels to the material and is reflected back
from the material. The Transducer then converts this energy back
into a signal and stops a counter in the microprocessor which
then, knowing the speed of sound through air, can accurately determine
the distance. The powerful software removes false echoes and the
electronic filter removes ambient noises.
