TJGL700 Series Radar Level Transmitters
Guided Wave Radar Level Gauge- Overview
- Brief Tech-Parameter
Guided wave radar is a gauge based on time stroke principle, the radar wave is running at speed of light, the running time can be converted to material level signal through electric components.
The sensor emit high frequency impulse and transmit along the cable, when impulse meets the material surface, it reflects back and is received by receiver inside the gauge, and converts the distance signal to material level signal.
