MODEL 300/301 PRE-CONFIGURATION WORKSHEET

This page is designed to be a worksheet where all the sys-

tem configuration data can be written down prior to entering

them into the unit. The system configuration is much faster

once all the data is known. This page can then be used for

future reference after the unit has been configured.

System configuration of the Model 300/301 is easily accom-

plished by inputting the following values as they relate to

your specific application:

Units: A selection for level units is required regardless of

whether level will be the primary measurement. This is

because the Model 300/301 calculates volume and flow from

the level that is measured in the vessel, flume, or weir. One

of the four level units shown on page 13 must be selected.

Volume or flow units must also be selected if the Level Only

mode is not being used.

Range: Range is defined as the distance from the face of the

ultrasonic transducer to the bottom of the level span. This

usually is the distance from the face of the transducer to the

bottom of the vessel. The maximum range for the Model

300/301 is 30' (9.1m).

Span:

Span is the distance from the bottom of the level

measurement to the top. The maximum span is the range

minus the dead band (18") of the ultrasonic transducer. The

maximum span for the 300/301 is 28.5' (8.7m).

Vessel Type: The Volume & Level mode will require one of

the nine vessel types shown on page 13 to be selected.

Equations to calculate volume from level are stored in the

software. If the application has a vessel type that is not list-

ed, then a custom table will need to be built using either a lin-

ear or spline curve.

Vessel Dimensions: Dimensional data will vary depending

on which vessel type is selected. See pages 18 & 19 for more

information.

Primary Flow Element: The Flow & Level mode will require

selection of one of the many flow elements to be selected

that are shown on page 14. Equations to calculate flow from

level are stored in the software. If the application has a flow

element that is not listed, then a custom table will need to be

built using either a linear or spline curve.

Reference Distance:

The reference distance is the open

channel flow equivalent to the range. See above.

Maximum Head: Maximum head is the open channel flow

equivalent to the span. See above.

Low Flow Cutoff: The low flow cutoff will force a zero flow

value when the level is at or below this point.
