Emerson Model 1700 Manual De Usuario

Overview

Flow Direction

controls how forward flow and reverse flow affect flow measurement and

reporting.

Flow Direction

is defined with respect to the flow arrow on the sensor:

•

Forward flow (positive flow) moves in the direction of the flow arrow on the sensor.

•

Reverse flow (negative flow) moves in the direction opposite to the flow arrow on
the sensor.

Tip

Micro Motion sensors are bidirectional. Measurement accuracy is not affected by actual flow
direction or the setting of the Flow Direction parameter.

Procedure

Set Flow Direction to the value you want to use.

Forward

Appropriate when the Flow Direction
arrow is in the same direction as the
majority of flow.

Reverse

Appropriate when the Flow Direction
arrow is in the same direction as the
majority of flow.

Absolute Value

Flow Direction arrow is not relevant.

Bidirectional

Bi directional

Appropriate when both forward and
reverse flow are expected, and for-
ward flow will dominate, but the
amount of reverse flow will be signifi-
cant.

Negate Forward

Negate/Forward Only

Appropriate when the Flow Direction
arrow is in the opposite direction from
the majority of flow.

Negate Bidirectional

Negate/Bi-directional

Appropriate when both forward and
reverse flow are expected, and reverse
flow will dominate, but the amount of
forward flow will be significant.
