Digital Bargraph Display Receivers -
163000 Series
Gems Digital Bargraph Receivers improve the way you are able to
visualize the data
being received from your liquid level transmitters. These new
receivers display
liquid level information in digital numerals in conjunction with a
0-100% LED
bargraph readout. The numeric portion is a 1/2? 4-digit display that
provides detailed
quantification of tank contents, while the bright LED bargraph
represents the tank
contents as a bar length relative to the percentage of fluid volume
within the tank.
If you have a non-linear tank, such as a sphere or a cylinder laying
on its side, these
receivers are a blessing. They can be calibrated easily so that the
digital and bargraph
displays will indicate accurate content information for odd shape
tanks. See
Linearization below.
In addition to the dual visual displays, the Gems Bargraph Receiver
features two
independent alarms with adjustable time delays, 10 amp auxiliary dry
contacts and
easy user set-up. The receiver is available in component form for
mounting into
custom enclosures or panels, or housed within a NEMA 4X enclosure.
Linearization
Certain tanks, like a sphere or a cylinder laying on its side, are
considered Non-
Linear in terms of volume versus tank height. In these cases this
receiver may be
linearized according to your tank parameters so that the correct
volume is displayed.
Any units may be displayed by the receiver. Gallons, inches, tons,
cubic inches, liters
and etc.
The receiver uses a scheme where 9 points or 8 straight lines are
used to calculate the
numbers to be displayed. These 8 lines approximate the curve of the
non-linear tank.
Examples of Non-Linear Display Values.
1.Gallons in a spherical tank.
2.Gallons in a cylindrical tank laying down.
3.Pounds of liquid in a spherical tank.
4.Cubic meters in a conical shaped tank.
5.Gallons in a non-linear shaped tank.
IMPORTANT: Customer must supply a sounding table, capacity curve
and/or tank
drawing for linearization of the digital bar graph display receiver.
