Siemens SITRANS FUS060 Operating Instructions Manual page 55

The density unit and value entered in this menu are used to convert the volume flow to mass
flow (see also menu 3.1.1 Unit).
Note
Input of density is unnecessary and ineffective when volume flow unit has been selected in
menu 3.1.1 Unit.
Flow direct (menu 3.1.5.1)
In this menu the setting of the main flow direction can be changed.
Meas. direct (menu 3.1.5.2)
The device is able to measure in both flow directions (forward and reverse) or in forward
direction only.
The possible settings are:
• Forward + reverse
• Forward only
If "Forward only" is selected, signals are output or accumulated internally for a flow in this
direction only.
Left figure: Forward and reverse flow. Right figure: Forward flow only

Hysteresis (menus 3.1.5.3, 3.2.3.3, 3.3.2.3 and 3.6.4)
Signaling of measured values can operate with a hysteresis set by the user. The setting is made
in % of full scale value (Max. vol. flow; menu 3.1.2). The setting range is 0 to 20 % of full scale
value with a default value of 1 %.
Example 1:
Hysteresis = 0 %
Digital output 1 = flow direction
