Nozzle Design - Siemens SITRANS L Series Compact Operating Instructions

Note
• On devices with a removable head, there is no limit to the number of times a device can
be rotated without damage.
• When mounting, orient the front or back of the device towards the closest vessel wall or
obstruction.
• Do not rotate the enclosure after programming and vessel calibration, otherwise an error
may occur, caused by a polarity shift of the transmit pulse.
