300-R010-45G Datasheet, PDF (12/36 Pages) Magnetrol International, Inc. – Echotel® Model 300/301 Ultrasonic Non-Contact Transmitter For Level/Volume/Open Channel Flow

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.
