Dual Frequency Radar Level Measurement

Application Problem: A customer required liquid level measurement for an application where the sensor installation was close to a concrete wall and ladder.

Application History: Level sensors from alternative brands picked up false echoes from the ladder and concrete wall, cause inaccurate readings.

Solution: ABM’s dual frequency self-adjusting radar sensor solved the problem with false echoes. On the echo profile only one echo from the liquid is detected.

“No problems at all. We have no need for special software to mask false echoes; this masking method was only good for the same liquid level. When liquid level changed a new set of parameters had to be downloaded. We couldn’t afford the echo processing software commonly used by other manufacturers.”
