Application Area
The Soliwave FDR56 microwave barrier utilizes a non-contact method for point level detection. Suitable for installation in tanks, pipelines, shafts, or free-falling sections. Capable of measuring through non-metallic wall materials externally. Functions as a level switch for monitoring and counting various bulk materials. Operates in conjunction with the Soliwave FQR56 transmitter.
Typical bulk materials: wood chips, sawdust or flour; gypsum, cement, ash; paper or cardboard scraps, gravel, sand, dry powders in general, bags and boxes.
