VEGA VEGAPULS 62 (≥ 2.0.0 - ≥ 4.0.0) 4 … 20 mA_HART four-wire Approval according to LPR radio standard - Manual (Page 19)

When using a surge pipe in a vessel, influences from vessel
installations and turbulences can be excluded. Under these prereq-
uisites, the measurement of products with low dielectric values (ε
r
value ≥ 1.6) is possible. In very adhesive products, measurement in a
surge pipe is not recommended.
