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 “NonLinear” 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.
