10 2551 Magmeter

K-Factor

060.000 >

K-Factor: See the charts in section 7.3 for values in pulses per U.S. gallon or in pulses per liter.

To use other units, convert the published values as appropriate.

Pipe Size: Select the pipe size that is nearest to the nominal pipe size.

Averaging: Set the averaging period based on the installation and  ow conditions. Smaller

values allow the 2551 to respond to changes in  ow rate quickly, while larger values smooth the

 uctuations caused by installation and  ow conditions. See section 7.1 for details.

7. Setup Menu

Flow Units: Set the units for the application. Four characters are available. The  rst three characters can be set to any symbol or alpha

character, upper or lower case. The following special symbols are located between the upper case and lower case menus:

• (centered dot)  (micro) _ (blank)

- (dash) / (slash) 3 (for cubic units)

The last character selects the timebase for the  ow rate measurement.

Select S/s (seconds) M/m (minutes), H/h (hours) or D/d (days)

Total Factor: Set the factor by which the totalizer will count. This setting is made in the

application units (i.e., gallons, liters, etc.)

Totalizer Units: Set the Totalizer Units. This setting serves as a label for the totalizer displays

only. It has no effect on the measurement. The special characters listed in the Total Factor

settings are available here also.

Low Flow Cutoff: Set a  ow rate that the 2551 Magmeter will use as a minimum threshhold.

If the  ow rate falls below this value, the 2551 will respond as if the  ow were zero.

Sensitivity: Set a percentage of maximum range by which the  ow must change to override the

averaging feature and "jump" quickly to the new  ow rate. See detailed explanation in section 7.1.

The Setup menu contains all of the parameters necessary for the 2551 Magmeter to begin

measuring  ow.

See the Options menu in section 11 for details.

The values shown for each menu item represent the factory

standard setting. All 2551 magmeters are packaged with these

settings.

Set 4 mA: (2551-22 and -42 versions only) Set the  ow rate where the current output will be 4 mA.

Set 20 mA: (2551-22 and -42 versions only) Set the  ow rate where the current output will be 20 mA.

The 4 to 20 mA output may be spanned to monitor forward and reverse  ow rates.
