4.7 Incorrect mounting
Foam generation
Thick foam on the product can cause incor-
rect measurements. Take measures to avoid
foam, carry out the measurement in a bypass
tube, or use a different measuring technol-
ogy, e.g. capacitive measuring probes or
hydrostatic pressure transmitters.
Foam generation
Orient the sensor perpendicularly to the product
surface
Wrong orientation to the product
Weak measuring signals are the result if the
sensor is not directly pointed at the product
surface. Orient the sensor axis perpendicu-
larly to the product surface to achieve opti-
mum measuring results.
Heavy turbulences
Strong product movements
Heavy turbulences in the vessel, e.g. by
strong stirrers or strong chemical reactions,
seriously interfere with the measurement. A
surge or bypass tube of sufficient size
(DN 200, DN 250) always allows, provided
the product causes no buildup in the tube, a
reliable measurement even with strong turbu-
lences in the vessel.
