Volume

Volume is used in two situations:

1. Calculate and display volume instead of level. For programming all setpoint

parameters in terms of volume units rather than level units.

2. Calculate pumped volume to accomplish the following:

• Totalize the volume of material that is pumped out of the wet well

If you require this functionality, please contact your local Siemens Milltronics

representative at www.milltronics.com

Readings

When using volume, readings are given in arbitrary units specified in P051.

The default is 100, which gives a reading in percent of total. Use whatever units you want

here. If the value is too large for the four-digit LCD, use a larger unit.

Example

If a wet well has a maximum capacity of 250,000 liters, use the value 250.0 for P051 and

set the reading in 1000s of liters.

Tank Shape and Dimensions

There are many common tank shapes to select from. (See P050. If possible, use one of

these.) Each tank shape uses the Empty distance (P006) in its calculations of volume.

Some tank shapes also require extra dimensions to calculate the volumes. Do not

estimate these values. They must be correct to ensure the accuracy of your volume

calculations.

To configure volume for a tank with a half-sphere bottom, set the

following:

Parameter Index Value Description

P050 1 4 selects the correct tank shape

P051 1 100 sets maximum volume at 100 (percent)

P052 1 1.3 sets A to 1.3m

Notes:

• The default reading changes to a range from 0 to 100 (the value in P051)

• Empty (P006) is still measured to the bottom of the tank, not the top of A.
