Endress+Hauser 61
SOUND VELOCITY
LIQUID
(6542)
Use this function to enter the sound velocity of the liquid.
Measuring the sound velocity of the liquid
If the sound velocity of the liquid is not known, it can be measured. To do so,
“SOUND VELOCITY LIQUID” must be set in the MEASUREMENT function
(6880, Page 63).
The sound velocity of the liquid is measured by calling up the SOUND
VELOCITY LIQUID (6542) function.
The measured sound velocity appears on the local display.
If you confirm the function with the
key, the SAVE prompt appears. To accept
the measured sound velocity, select the option “YES” by means of the
or
key.
