Level measurement of foaming liquids

Trials of the updated LFP Inox in UK industrial process applications have shown that excellent success rates are possible for measuring levels accurately in liquids such as milk, beer and detergents in the presence of  wet, dense foams.  The results show significant cost savings are likely for vessel level measurement and bottle filling applications.

False readings can be a common problem in level measurement using multi-point float switches, capacitive sensors or hydrostatic pressure sensors. The LFP Inox is a hygiene-compliant level probe that uses guided radar technology, so it is largely unaffected by a liquid’s density or conductivity.

The stainless steel probe of the SICK LFP Inox can be cut down from its maximum four metres length to suit the vessel dimensions, and can even be used in small vessels, thanks to its deadband of just 25mm.

With a hygiene-rated IP69K housing, the LFP Inox covers temperatures from -20oC to +150oC and pressures from -1 to +16 bar making it suitable for a wide range of processing conditions.  It is resistant to the thermal shock from rapid temperature changes and cleaning cycles with aggressive chemicals.

The easy to read on-unit display gives real time level and status information and makes LFP Inox  very simple to set up and commission.
