This continuous level measurement for liquids and bulk solids is based on the propagation time measurement of microwave pulses according to the principle of time domain reflectometry (TDR), which are guided along a rod or a rope. Its output power can vary between 0. Working of an isolator is very simple and it can be operated in various ways such as fully-automatic, semi-automatic or manually operated. All latest electronics and redesigned mechanical construction provide even better reliability, easier installation and the tremendous accuracy of the microwave measurement principle. we are a patriot organization that believes in upholding the united states constitution.
