Emerson IFT9701 Flow direction, Effect of flow direction on outputs and totalizers

Configuration with a HART Communicator continued

To enter an internal damping value, use the menu below and follow these steps:

1	Process variables					1	Flo unit
2	Diag/service	1	Charize sensor			2	Flo cutoff
3	Basic setup					3	Flo direction
4	DETAILED SETUP	2	CONFIG FLD	1	FLOW	4	FLOW DAMPING
			DEV VAR
5	Review			2	Density
		3	Config outputs
				3	Temp unit
		4	Device

1. At the online menu, choose 4 (detailed setup).

2. At the detailed setup menu, choose 2 (configure field device variables).

3. At the configure field device variables menu, choose 1 (flow).

4. At the flow menu, choose 4 (flow damping).

5. Select the desired damping value.

6. Press F2 (send) to send the damping value to the flowmeter memory.

6.2.5 Flow direction

The configured flow direction (forward, reverse, or bi-directional) determines how flowmeter outputs and totalizers will react when fluid flows through the meter. The flow direction arrow on the meter is considered the "forward" flow direction, but the meter measures flow accurately in either direction.

To configure flow direction for the meter, use the menu below and follow these steps:

1	Process variables
2	Diag/service	1	Charize sensor			1	Flo unit
3	Basic setup					2	Flo cutoff
4	DETAILED SETUP	2	CONFIG FLD	1	FLOW	3	FLO DIRECTION
			DEV VAR
5	Review			2	Density	4	Flow damping
		3	Config outputs
				3	Temp unit
		4	Device

1. At the online menu, choose 4 (detailed setup).

2. At the detailed setup menu, choose 2 (configure field device variables).

3. At the configure field device variables menu, choose 1 (flow).

4. At the flow variables menu, choose 3 (flow direction), then choose the desired option. The table below lists how outputs and totalizers are affected by the option that is chosen.

5. To send the flow direction to the flowmeter, press F2 (send).

Table 6-1 Effect of flow direction on outputs and totalizers

Fluid flow	Output or	Flowmeter configuration
direction	totalizer	Forward	Reverse
Fluid flowing	Milliamp output	Output increases as flow rate	Output goes to 3.8 mA
in same direction		increases
as flow arrow	Pulse output	Output increases as flow rate	Output remains at 0 Hz
on sensor		increases
	Internal totalizers	Flow totals increase	Flow totals remain constant
Fluid flowing	Milliamp output	Output goes to 3.8 mA	Output increases as flow rate
in opposite direction			increases
from flow arrow	Pulse output	Output remains at 0 Hz	Output increases as flow rate
on sensor			increases
	Internal totalizers	Flow totals remain constant	Flow totals increase
