Feature
RADAR TYPE LEVEL INDICATOR VF Series
The radar type level meter irradiates microwaves via the probe and makes stable detection without being affected by dust particles, vapors, and obstacles in the tank.
- Can be used for powders, granules, liquids, slurries, etc.
- Makes stable detection without being affected by the moisture content, particle diameter, and electrical properties of the measured substance.
- As microwaves are irradiated via the probe (wire or rod), the meter is not easily affected by vapors (for liquids) and dust particles (for granules).
- Adjustment after installation is not needed.
Operating Principles
When an electromagnetic pulse is applied on the sensor probe, the pulse proceeds at high speed toward the measurement surface via the wire, and a part of the pulse is reflected on the measurement surface and returned to the sensor. The distance to the measured substance is calculated from this propagation time.
