The radar level transmitter antenna emits and narrows the microwave pulse. This pulse propagates in space at the speed of light. When it encounters the surface of the measured medium part of its energy is reflected back and received by the same antenna. The time interval between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium. Due to the extremely high propagation speed of electromagnetic waves the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). It is difficult to confirm. The 90X series 26G radar level gauge uses a special demodulation technology to accurately identify the transmitted pulse and The time interval of the pulse is received to further calculate the distance of the antenna from the surface of the measured medium.
Measurement range up to 70 meters covering water level measurement of large reservoirs.
Small antenna size easy to install and add dust cover and other antenna protection devices.
Light weight is about 1KG easy to install.
Multiple output circuit interfaces cooperate with the acquisition system.
Small beam angle concentrated energy stronger anti-interference ability greatly improving measurement accuracy and reliability
Using pulse working mode the radar level gauge has very low transmission power and no harm to human body and environment.
