Specification
Radar Level Gauge NM700
Product Overview
The Radar Level Gauge NM700 Series is a high-performance non-contact radar level transmitter designed for continuous level measurement in tanks, vessels, silos, and storage containers operating under demanding industrial conditions.
Utilizing advanced microwave pulse radar technology, the NM700 provides accurate and reliable level measurement without contacting the measured medium. It is ideal for applications involving liquids, slurries, powders, and bulk solids, even in environments with significant temperature and pressure variations.
The NM700 adopts two-wire technology, making installation simple while reducing wiring costs. It also supports explosion-proof applications and offers a maximum measuring distance of 70 meters, making it suitable for a wide range of industrial process control applications.
Operating Principle
The Radar Level Gauge NM700 operates using microwave pulse radar technology.
The radar antenna continuously emits high-frequency microwave pulses toward the surface of the measured medium. The pulses are reflected back to the antenna, and the instrument calculates the distance by measuring the travel time of the reflected signal.
The measured distance is then converted into an accurate level value. Since the measurement is non-contact, the radar level gauge is not affected by changes in the physical properties of the medium, ensuring stable and reliable performance under harsh operating conditions.
