Applications
|
|
|
| Level is one of the most common
applications for Precision Digital products and we offer a wide
variety of products to satisfy just about any level display
and control application you might have. Our products can power
the level transmitter, be scaled in any engineering unit and
linearized for non-linear shaped tanks, control pumps and valves
with up to four relays, connect to a computer, and output a
4-20 mA signal. In addition these meters are available in a
wide variety of enclosures ranging from panel mount to NEMA
4X to explosion-proof and carry approvals such as FM, CSA, and
UL. |

Boiler Drum Level
|
Products: PD690,
PD692,
PD650,
PD655,
PD656 |
The PD650 monitors and controls
the boiler drum level and displays it on a large, easy to read
digital display that can be seen at great distances.
• Large display
can be seen across the room
• Four relays for
alarm and control
• Rugged cast aluminum
enclosure
• Transmitter power
supply
• Wall or panel
mount

Pump Alternation Control
|
Precision Digital products are used in many applications for
pump control because they are simple to use, provide local display
of level, power the transmitter, and can be used for pump alternation.
Many Precision Digital products can have up to four relays,
(the ProVu can have eight!) so at least two can be used to control
the pumps and two can be used for high and low alarm. The pump
alternation feature is particularly useful because it extends
the life of the pump and reduces maintenance costs.
|
• Simple
to use
• Local level display
• Power the transmitter
• High and low
level alarm
• Pump alternation
control
|
Relay #4 turns the main pump on at 6000 gallons and turns
it off at 1000 gallons.
|
With the Pump Alternation feature activated, the next
time the level reaches 6000 gallons, relay #3 transfers
and starts the backup pump.
|
If the backup pump is not able to keep up, and the level
reaches 7000 gallons, relay #4 transfers and starts the
main pump as well.
|
Relay #2 trips the High Level Alarm at 7500 gallons and
resets at 6900 gallons.
|
Relay #1 trips the Low Level Alarm at 495 gallons and
resets at 750 gallons.

Tank Farm Level Monitoring
|
Precision Digital products can display and control level in
multiple tanks in one central location. This can be done using
individual digital displays or one ConsoliDator. The advantage
of the ConsoliDator is that it provides much more information
about the tanks than individual displays can. For instance,
the ConsoliDator provides both a bargraph and a numeric display
of tank level.
|
• Monitor up to
eight tanks
• Bargraph and
numeric screens
• 32-point linearization
• Display in feet
and inches (3' 7")
• Pump alternation
control
• Low and high
level alarms
• RS-232 Modbus

Chlorine tank volume measurement
|
 |
Precision Digital's model PD690
digital process meter powers and displays the 4-20 mA output
from the Solartron level transmitter. The PD690's multi-point
inearization feature provides a display in volume from these
round horizontal tanks. An optional NEMA 4X enclosure provides
protection from the elements and a convenient way to mount the
meters on the wall.

Volume for Non-Linear Tanks
|
Precision Digital has products that can display volume in just
about any shape tank. These products include Precision Digital
meters, Fluidwell products and the ConsoliDator. All of these
products allow the user to enter multiple calibration points
to linearize the non-linear aspect of the tank. In addition,
these products can provide relays for control and alarm purposes,
power to the transmitter, and linear 4-20 mA output.

• Linearize just

• Relays for alarm
& control
• Power the transmitter
• Linear 4-20 mA

Fluidwell Products
Product: Fluidwell
F173 |
Fluidwell provides a wide variety
of products for level display and control. These products range
from the basic F070 linear level indicator with its 1 inch high
digits to the sophisticated F173 for non-linear tanks. The F173
(pictured here) can provide up to 15 points of linearization,
four alarm outputs, a linear analog output an serial communications.
Like all Fluidwell products, it can be housed in a rugged NEMA
4X enclosure and loop, AC or DC powered.

Local Level Display & Remote PC Monitoring
|
Say you have an application where you want to display the level
from 6 tanks right out at the tank farm and also display the
data and collect it on your computer back in your office. You
can do this with Precision Digital's Trident meter and MeterView®
software. We can provide the enclosure and the engraved labels
so you have everything you need.! MeterView software even allows
you to remotely acknowledge relays. |

Level measurement in hazardous area
|
 |
 |
| Precision Digital's model PD656
Explosion-proof meter is powering the level transmitter and
displaying its output on an easy to ready 0.8" high LED
display. The PD656 can be equipped with up to four relays that
feature 0-100% deadband and pump alternation capability. |

Annunciator for level switches
|
Products: PD154 & PD158 Vigilante
II Annunciators |
The Vigilante® II annunciators are compact, panel-space
saving, easy to use annunciators available in models to handle
either four or eight level switches. Each switch can have its
own custom message, such as "Tank One High Alarm",
on the Vigilante. When a level switch trips, the LED for that
input flashes, a horn sounds and a relay transfers. The Vigilante
annunciator can even indicate which switch tripped first.
