Page 4: １ ．Overview
It measures with a suitable frequency which is given by phase detection using received signal reflected from the storage surface and transmission signal. ２． Specifications Table 1. Specifications Item Specification Type MWLM-FM79 Version Antenna Lens Power supply （#1） DC12V to DC36 V Power consumption 800 mW Equivalent JIS10K100A flange ●... - Page 5 (#1) No interfusion of noise surge with less 10% of ripple on power supply voltage for instrumentation. Maximum load resistance depends on power supply voltage. Please refer Fig.1. Make sure that wiring load will not over maximum load resistance value on applied power supply voltage.

- Page 12 -Do not install instrument close to inlet of material charging. Fig. 9. Installation precaution (2) -No obstruction with noise in range of radar beam. Fig. 10. Installation precaution (3) - For liquid application, keep vertical position to material surface. Fig. 11. Installation precaution (4)
- Page 13 (Noise reflection) Noise reflections can cause inaccurate or unstable level measurement. Noise reflection can be treated by adjustment app. In case of receiving no reflection or quite small dB from the material surface, the installed position must be changed. If there is any such obstruction in the tank, please install the transmitter where there is no obstruction within the range of beam angle.
