TR91 Intelligent Pulse Radar Level GaugeDetailed product description：

The TR91 intelligent pulse radar level gauge antenna emits extremely narrow microwave pulses, which propagate at the speed of light in space. When they hit the surface of the measured medium, some of their energy is reflected back and received by the same antenna. The time interval between transmitting and receiving pulses 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, it is difficult to confirm the time interval between the emitted pulse and the received pulse, which is very small (in the nanosecond range). The radar level gauge adopts a special correlation demodulation technology, which can accurately identify the time interval between the transmitted pulse and the received pulse, and further calculate the distance from the antenna to the surface of the measured medium. The ULS54 intelligent pulse radar level gauge is widely used in storage containers or process containers with complex process conditions and small dielectric constant media.
