Dished tank ends
On dished tank ends, please do not mount
the instrument in the centre but approx. 1/2
vessel radius from the centre. Dished tank
ends can act as paraboloidal reflectors for
the ultrasonic pulses. If the transducer is
placed in the "focus" of the parabolic tank
end, the transducer receives amplified false
echoes. The transducer should be mounted
outside the "focus". Parabolic amplified ech-
oes are thereby avoided.
