We are proud to introduce the FLT91001 Guided Wave Radar Level Transmitter, a professional industrial measurement instrument designed for accurate and reliable contact level monitoring in harsh industrial environments. As a core product in our level measurement lineup, the FLT91001 Guided Wave Radar Level Transmitter leverages advanced time-of-flight radar technology, making it the ideal choice for high-temperature, high-pressure liquid and solid level measurement across various industrial applications.
The FLT91001 Guided Wave Radar Level Transmitter operates on the time-of-flight principle, where radar waves travel at the speed of light and convert travel time into level signals. The probe of the FLT91001 Guided Wave Radar Level Transmitter emits high-frequency pulses that propagate along a cable or rod probe. When the pulse hits the material surface, it reflects back to the receiver inside the FLT91001 Guided Wave Radar Level Transmitter, which converts the distance signal into a level signal. The FLT91001 Guided Wave Radar Level Transmitter supports deep customization to meet specific project requirements.
The FLT91001 Guided Wave Radar Level Transmitter offers multiple measurement ranges to accommodate various tank sizes: M1-10m, M2-20m, M3-30m, M6-60m, and MB-90m. This wide range flexibility makes the FLT91001 Guided Wave Radar Level Transmitter suitable for small process tanks and large storage silos.
The FLT91001 Guided Wave Radar Level Transmitter supports full remote maintenance, OTA (Over-the-Air) updates, remote access, radar management, and remote firmware upgrades. This feature significantly reduces on-site maintenance costs and downtime for the FLT91001 Guided Wave Radar Level Transmitter, improving operational efficiency.
Our FLT91001 Guided Wave Radar Level Transmitter is equipped with comprehensive physical interfaces, including 4~20mA (optional 2-channel), HART, AUTBUS, Fieldbus Foundation, Profibus PA, and NB-IoT. This extensive connectivity ensures seamless integration with existing industrial control systems, maximizing the efficiency of the FLT91001 Guided Wave Radar Level Transmitter in automated production lines.
The FLT91001 Guided Wave Radar Level Transmitter supports Bluetooth wireless debugging function, allowing for convenient on-site configuration and real-time monitoring. It also features a backlight display that provides clear and easy-to-read measurements even in low-light environments, significantly enhancing the user-friendliness of the FLT91001 Guided Wave Radar Level Transmitter.
The FLT91001 Guided Wave Radar Level Transmitter excels in TBF (Tank Bottom Reflection) measurement for media with low dielectric constants (less than 1.5). It performs reliably in harsh working conditions such as steam, dust, and crystallization, making the FLT91001 Guided Wave Radar Level Transmitter ideal for the most challenging industrial environments.
