QDY70B-C3 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.
The meter’s all input and output lines must be with such protection functions as lightning protection and short circuit prevention.
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.
