Changing the measurement mode parameter

The measurement mode parameter defines how the flow is added to or subtracted from the totalizers.
• Forward flow moves in the direction of the arrow on the sensor.
• Reverse flow moves in the direction opposite from the arrow on the sensor.
Table 4-15 shows the possible values for the measurement mode parameter and the transmitter's
behavior when the flow is positive or negative. Only the unidirectional and bidirectional values are
recognized by the PROFIBUS specification, so other values will be unrecognized by a PROFIBUS
host or configuration tool. However, the transmitter will operate correctly in any of the modes listed in
Table 4-15.
