http://youtu.be/RyvHkN4Iay8
The Micropilot NMR81 features a unique drip-off antenna design and transmitting frequency that produces a sharply focused beam angle of 3°. The 79GHz technology is highly reliable even in tall narrow tanks or close to tank walls because the radar beam avoids objects such as pipes or baffles. The NMR81 is designed for tank gauging applications with all relevant custody transfer certificates.
