LRT-1902TAnti-crystallizationType radar level gauge
Excellent low temperature resistance and anti-crystallization properties
Not afraid of low temperatures,Just because i canSpontaneous heating
The LRT-1902T series sensor is a 26G high-frequency radar level measuring instrument with a measuring distance of up to 80 meters. The antenna has been further optimized, and the new fast microprocessor can perform higher-speed signal analysis and processing, allowing the instrument to be used for measurement of various highly corrosive liquids.
● Will be heatedLevel instrument, Low temperature resistance, Self heating,NoFreeze, Anti-crystallization.
● Almost unaffected by corrosion and foam; almost unaffected by water vapor, temperature and pressure changes in the atmosphere.
● Serious dust environment has little impact on the operation of high-frequency level meters.
● The wavelength is shorter and reflects better on tilted solid surfaces.
● The beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference.
● The measurement blind area is smaller, and good results can be achieved for small tank measurements.
● High signal-to-noise ratio for better performance even under fluctuating conditions.
● High frequency, it is the best choice for measuring solids and low dielectric constant media.
Applications:
● Secondary water supply pipe network,
● Large water users,
● Zone metering,
● Pipe network leakage monitoring
● Monitoring and measuring of water quantity
