EN 50081-1, EN 50082-2; NAMUR Recommendation
No effect on measurement results; to ensure reliable measurements, the
relative permittivity should have the following minimum values:
ε r > 1.5; ε r < 3: stilling well recommended; Wave-Stick immersed: ε r > 4
Liquid a mmonia (NH 3 ); liquid hydrogen (H 2 ); liquid helium (He)
unrestricted (but be aware of ambient and flange temperatures)
dependent on flange size and pressure rating (see Table)
