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.
