QTLM Ultrasonic level gauges/Ultrasonic level transmitter includes several proprietary technologies, is safe and clean, with high precision and long service life, stable and reliable, and convenient to install and maintain, and is applicable to various fields of acid, alkali, salt, anticorrosion, and high temperature.Ultrasonic wave spread speed among gas is influenced by gas temperature, When level meter works, it measures gas temperature needing, compensates for the velocity of sound, so as to ensure the precision of measuring.Ultrasonic pulses generated by the sensor (transducer) emitted in the measurement, the surface acoustic wave after reflection by the liquid receiving same sensor or an ultrasonic receiver.
