Major Functions
- Check measurements (level, echo etc) through liquid crystal display
- Check level in dark places using built-in back-light
- Air purge function
(Prevent foreign material from being attached on sensor) - Noise removal function
How It Works
RADAR level meter is measured by short microwave pulse signal emitted from antenna installed on upper
part of tank.
Microwave pulse signal is reflected on the surface then reflected wave is received by antenna.
Distance between level meter and the surface (d) is proportional to transmission time of microwave pulse signal (t).
Distance = Speed × time
L = C×T/2
