Level Measurement
Level instruments chosen by range and blind zone, foam, steam, agitation, and whether the medium’s density is stable.
Pressure (Hydrostatic)
Hydrostatic level: a pressure sensor plus an assumed density. A changing density is a systematic error no temperature…
Radar
Non-contact radar for steam, foam, dust and pressurised tanks. 80 GHz for small tanks and tight beams, 26…
Sludge / Interface
Sludge blanket and interface measurement in settling tanks, and level difference across screens and channels.
Ultrasonic
Non-contact level for open or vented tanks, wells and channels. Blind zone grows with range; foam, steam and…
