Holykell 26G High Frequency Non Contact Guided Wave Radar Level Sensor

Radar Level Gauge is a liquid (material) level recording instrument in the measurement. The microwave pulse is sent by the antenna,and then is reflected by the material surface , then is received by the radar systems. Then is sent to the electronic circuit, the microprocessor can identify the microwave pulse echo regenerate the material or the surface of the liquid. The correct signal is done by intelligent software, up to millimeter accuracy, nonapplicable harsh environments.
