Application field
The product is especially suitable for penetration measurement outside the tank or see-through measurement through a quartz glass isolation flange in a high temperature and high pressure reactor environment
The electromagnetic wave emission angle of the product is less than 4°, which is suitable for measurement in narrow spaces or guided wave pipes
The product can reach 30M measurement range, suitable for the measurement of super large storage tanks
The product has extremely high measurement accuracy, especially suitable for high-precision metrology-level measurement
The product has rich echo processing algorithms and experience data of various industrial and mining environments; it has unique advantages that other similar products do not have for extremely harsh working conditions such as strong dust, steam, and storage tanks with special processes such as stirring and heating rods.
