高频雷达作为主要的液位测量方式已经有超过30年的历史。高频雷达原先的设计是用于恶劣和复杂的工况，并且需要单独进行电源供电;随着技术逐步成熟，轻量化、回路供电技术的使用，INTO的高频雷达很好的延续了这一技术变化。

微波技术的雷达通过测量方面的技术操作可以适用于大部分的应用领域，同时可以通过元器件的更新取得更低的器件成本，可以非常容易地替换超声波液位计，用于日常的液位测量用途。

Radar has been part of the level measurement market for more than thirty years. The early designs used in tank gauging were heavy, expensive, power-hungry and complex. Advancements in radar circuitry have evolved the modern radar transmitter so that now it is light, inexpensive, loop-powered and easy to use. The INTO non-contact radar is the logical extension of that evolution.

Microwave-based radar is a superior measurement technology with its ability to operate effectively in a wide range of process conditions. It has been too expensive to use as a replacement for ultrasonic transmitters in simple, daily applications...until now. The radar transmitter can be considered the answer to almost every daily level measurement application imaginable.
