Corrosion-Resistant Radar Level Gauge
Page Features:
Non-contact, High Accuracy, Corrosion Resistant
High Frequency, Suitable for Measuring Solids and Low Dielectric Constant Media
Easy Installation, Contamination-Free
Product Overview:
The corrosion-resistant radar level gauge measures liquid level based on the time difference between radar wave transmission and reception. It features non-contact operation, high accuracy, corrosion resistance, and immunity to pressure influence, meeting most measurement requirements. Suitable for open-air or enclosed tank level measurement. The product includes a display, offers optional explosion-proof certification, and has a settable range of up to 120 meters.
Features:
Small antenna size for easy installation; non-contact radar ensures no wear or contamination.
Virtually unaffected by corrosion or foam; minimally impacted by atmospheric vapor, temperature, and pressure changes.
Severe dust environments have minimal impact on high-frequency level gauge operation.
Shorter wavelength provides better reflection on inclined solid surfaces.
Small beam angle concentrates energy, enhancing echo strength and aiding in avoiding interference.
Smaller measurement blind zone ensures good performance even in small tanks.
High signal-to-noise ratio delivers superior performance even under turbulent conditions.
High frequency enables measurement of solids and low dielectric constant media.
