Base Volume Unit

Fast Keys

1, 3, 2, 2, 2

Base volume unit is the unit from which the conversion is being made. Set this variable to the appropriate option.

Conversion Number

Fast Keys

1, 3, 2, 2, 3

The special units conversion number is used to convert base units to special units. For a straight conversion of volume units from one to another, the conversion number is the number of base units in the new unit. For example, if you are converting from gallons to barrels and there are 31 gallons in a barrel, the conversion factor is 31.

Base Time Unit

Fast Keys

1, 3, 2, 2, 4

Base time unit provides the time unit from which to calculate the special units. For example, if your special units is a volume per minute, select minutes.

Line Size

Fast Keys 1, 3, 3

Special Flow Rate Unit

Fast Keys 1, 3, 2, 2, 5

Special flow rate unit is a format variable that provides a record of the units to which you are converting. The Handheld Communicator will display a special units designator as the units format for your primary variable. The actual special units setting you define will not appear. Four characters are available to store the new units designation. The 8732 LOI will display the four character designation as configured.

Example

To display flow in barrels per hour, and one barrel is equal to 31.0 gallons, the procedure would be:

Set the Volume Unit to BARL.

Set the Base Volume Unit to gallons. Set the Input Conversion Number to 31. Set the Time Base to Hour.

Set the Rate Unit to BR/H.

The line size (flowtube sensor size) must be set to match the actual flowtube sensor connected to the transmitter. The size must be specified in inches according to the available sizes listed below. If a value is entered from a control system or Handheld Communicator that does not match one of these figures, the value will go to the next highest option.

The line size (inches) options are as follows:

0.1, 0.15, 0.25, 0.30, 0.50, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 28, 30, 32, 36, 40, 42, 44, 48, 54, 56, 60, 64, 72, 80
