1.6.2 Floats
Four float types are used for liquid level measurement.
• Floats 1 and 2 are made of either 316L or 316Ti (as ordered).
• Floats 3 and 4 are made of titanium
The float number identifies the wall thickness of the float and the material used.
The dimension “a” in the diagrams below gives the distance from the base of the float to the centre
line of the integrated magnet system. This should be used in calculations for adjustments to the
measuring scale caused by differences between true liquid-level zero and indicated scale zero (see
section 1.6.4).
316L or 316Ti floats-No.1 and 2
Titanium floats-No. 3 and 4
where a = 47 mm or 1.85“ where a = 48 mm or 1.89“
and :
Float No.1 wall thickness = 1mm or 0.04”
Float No.2 wall thickness = 0.5mm or 0.02” and :
Float No.3 wall thickness = 0.6mm or 0.024”
Float No.4 wall thickness = 1mm or 0.04”
Dimensions in mm (inches)
Note
Minor variants of the above exist for particular applications: very low density products, interface
measurement applications and so on. Contact KROHNE for further information.
