Product overview Instrument Introduc�on Sensor is 26G High Frequency radar level measurement instrument, measure the maximum distance to 70 meters. Antenna being further op�mized, fast new microprocessor could be higher-speed signals processing, makes the instrument can be used in reactors, solid-state storage bin and some complicated measuring condi�ons. YLR806A1 Applica�on: All kinds of corrosive liquids Measurement Span:0 to 20 meters Process Connec�on: Thread or Flanges Radar antenna send narrow microwave pulses and pass antenna transfer downward. Microwaves reflected back into contact...

The Installa�on Requirements Installa�on Guide Tapered tank cannot be installed on the top of the feeding mouth. TAlso note: outdoor installa�on should be taken sunshade, Rainproof measures. Installed in the 1/4 or 1/6 diameter of tank. Note: the minimum distance from the tank wall should be tank high 1/10. Note: ① base level ②Container central or axis of symmetry ① Right The instrument cannot be installed in the middle of an arch or a circular tank top. In addi�on to produce indirect echo is also affected by the echoes. Mul�ple echo can be larger than the true value of signal echo, because...
