LRT-G1800 high-end radar level meter Limited-time offer
It is suitable for position measurement under extreme temperature and pressure, strong corrosive and other working conditions.
LRT-G1800 high-end radar level meter is ausing the radar wave emission and reception time differenceprinciple for level measurement, withNon-contact, strong corrosion resistance, wide range of measurement conditions, not affected by pressure, covering most measurement requirements. Suitable forStrongly corrosive liquidsLevel measurement, productsWith display, optionalExplosion protection, 70 meter range can be set.
LRT-G1800 high-end radar level meterThe sensor series is a 26G high-frequency radar level measuring instrument with a measuring distance of up to 25 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 position measurement in highly corrosive working conditions.

● Compact antenna for easy installation; non-contact radar with no wear or contamination.
● Virtually unaffected by corrosion or foam; nearly immune to atmospheric water vapor, temperature and pressure changes.
● Heavy dust environments have little effect on high-frequency level meter operation.
● Shorter wavelength gives better reflection off inclined solid surfaces.
● Narrow beam angle concentrates energy, strengthening echo performance while avoiding obstructions.
● Smaller blind zone delivers good results even on small tanks.
● High signal-to-noise ratio maintains superior performance even under agitation.
● High frequency, measuring solids and low dielectric constant media.
