The efector gwr level sensor provides all of the advantages of reliable level detection using innovative guided wave radar technology at a very low price. Alternative level solutions may offer a lower price but may not perform in challenging applications.

Mechanical float switches can stick in an application due to metal deposits. Vibration forks offer slightly better performance, but many are required to detect the level of the medium. Traditional GWR level sensors offer an improved performance, but at a very high price point.
