1 FMCW Radar Level Transmitter

2 PRODUCT INTRODUCTION FMCW Radar level transmitter is a non contact measuring device, which is suitable for high temp., high pressure, and corrosive applications. It is easy to install and free of maintenance, especially for the high accuracy requirement environment. PRINCIPLE FMCW radar adopts a high frequency signal, which is emitted via an antenna and swipe frequency increment by 0.5GHz during the measurement, reflected by the target surface and received at a time delay. The frequency difference, which is calculated from the transmitting frequency and the received frequency, which is directly proportional to the measured distance (or material surface). The frequency difference then is processed by Fast Fourier Transformation (FFT) to identify the signal in Intermedium Frequency (IF). This FMCW radar is innate with signal / noise enhancement and filtering of echo-back via Phase-Lock Loop (PLL) circuit that is the best solution for complex environment and high accuracy measurement. FEATURES Non contact measuring Corrosive and toxic liquid, hydrocarbons, slurries Not affected by specific gravity, pressure, temperature, viscosity, foam, and dust 5 digits LCM display Indicate signal wave inside the silo. Selection of Different Measurement unit(m, cm, mm, inch, ft, %, ma) Measuring distance and actual level. Language selection of traditional Chinese, simplified Chinese, English. -0mA/ lead wires Modbus RS-85 to enhance isolation and easy for remote control.

7 SOFTWARE SETUP CALIBRATION Software Setup Calibration(FAS) FAS calibration software can be utilized with JFR Series via RS85/RS3 to allow tank data reading and setup from PC. Parameter Description Low Point: Low point(ma), measuring range from flange to low level. High Point: High point(0ma), measuring range from flange to high level. Blind Area: Blind distance, distance starts from flange surface. Max. Distance: Measuring range between low point nd high point. FAS Operation Instruction. Turn on FAS software. Go to Address, then choose 9600, COM5 from baudrate 3. Click on Connect.. Press "Stop Sync" to change parameter. 5. Press "GetFFT" to read wave reflection diagram. Press "Stop Sync" to change preset parameter. 6

8 INSTALLATION If the JFR-3 is installed on a neck, refer to the limitation on the length and the diameter as below. The horn of the JFR-00 can not hide in the neck. The horn has to expose itself to the tank by 0.39 at least The axis direction of FMCW should be parallel with the wall, or be in orthogonal with the surface. For Install, the distance from the wall should >/3 D, and the height from the surface >/5 H (Measurement Depth) is recommended. 60mm max. (L)5mm D H >/5H Max.</3D 50mm min. Device has to be installed away from the tank wall to avoid disturbance caused by reflection. The turbulent or stirring will make the bubble and vortex that might interface with the measurement, it is recommended to install wave shield tube with vent hole To avoid from this situation. Device has to be installed away from the tank wall to avoid incorrect reflection. vent hole Device is to be installed away from material inlet to avoid disturbance caused by material or other obstacles. A reflector is recommended to be installed when there is disturbing obstacle to avoid false reflection. Please avoid center installation for arched top tanks for possible multiple reflection. Reflector Sun/rain block is recommended for outdoor application. The best installation position for cone shape tank with flat top is at the center spot for full measuring range. 7
