Radar Level Meter Antenna low emission energy extremely short microwave pulses,the pulses of light propagation in space,measured across the media surface,some of its energy is reflected back,is received by the same antenna,Transmit pulse and the received pulse intervals proportional to the distance to the north side of the antenna surface of the medium,Due to high velocity of propagation of electromagnetic waves emitted pulse and pulse interval time to accept a small(nanoseconds)is difficult to confirm,TEMHRD Series Radar Level Meter uses a special technology related solutions that can accurately identify the time interval between the transmitted pulse and the reception,the antenna further calculate the distance to the surface of the measured medium .
