Burkert Type 8136 - Manual (Page 20)

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.
