1. Description
ProcessPro transmitters are available in two styles: panel mount and field mount. The panel mount is supplied with the necessary
hardware to install the transmitter. This manual includes complete panel mounting instructions.
Field mounting requires one of two separate mounting kits. The 3-8052 integral kit joins sensor and instrument together into a single
package. The 3-8050 Universal kit enables the transmitter to be installed virtually anywhere.
Detailed instructions for integral mounting or other field installation options are included with the 3-8052 Integral kit or the 3-8050
Universal kit.

4.2 Serial Data Connections
• The Input/Output terminals on the 8250 carry S3L serial data from the 2450 Pressure Sensor or from the 2250 Level Sensor and
from the External Relay Module.
• You MUST reset sensor configuration (see Calibrate menu) for all new systems and after connecting a new sensor or relay module
to the I/O terminals.
• Do not route sensor or output cables in conduit containing AC power wiring. Electrical noise may interfere with sensor signal.
• Routing cable in grounded metal conduit will help prevent electrical noise and mechanical damage.
• Seal cable entry points to prevent moisture damage.
• Only one wire should be inserted into a terminal. Splice double wires outside the terminal.
• The TOTAL cable length from I/O devices to the transmitter must not exceed 122 m (400 ft.).
• For best performance, ground the sensor SHIELD wire to a local earth ground at a point near the sensor.
• Consult the sensor manual for additional wiring information.

Zero reference point (Z):
The point in the vessel where you want the 8250 to display zero
(0 ft., 0 gal. etc).
• If Z is located below the fluid surface, the 8250 will display
a positive level measurement.
• If Z is located above the fluid surface, the 8250 will display
a negative level measurement.
Sensor Location point (SLoc):
The point on the level sensor where the measurement is taken.
• The 2450 Pressure sensor measures from the centerline of
the diaphragm.
Offset (O):
The distance from Z to SLoc.
• Enter a positive value in the Calibrate menu if the sensor is
located above Z.
• Enter a negative value in the Calibrate menu if the sensor
is located below Z.
• Enter 0 in the Calibrate menu if the sensor is located at Z.
Level (L):
The distance from Z to surface of fluid (displayed as "Level"
by transmitter).

For horizontal cylinders only, the
zero reference point MUST be
the lowest point in the vessel.
For most vessels, the zero
reference point may be
designated as any height
in the vessel.
5. System Configuration
The 8250 Level Transmitter must be programmed using the following system configuration procedure.
1. Determine where you want the level measurement to start. This is the Zero reference point (Z).
Review the diagram to help select the best option.
2. Determine where you will mount the sensor. This is SLoc.
Consult the Sensor manual for information regarding the best location for the sensor.
3. Measure the distance between Z and SLoc. This is O(ffset).
4. Enter the Offset into the Calibrate menu.

Custom point #5 250 gal.
Custom point #9 1300 gal.
Custom point #6 380 gal.
Custom point #7 700 gal.
Custom point #8 1000 gal.
If Custom Shape is selected in the Options menu, you can define
from two to ten Custom Points to establish the relationship of
level to volume in the vessel.
• Select Manual level Measurement mode to edit both level and
volume data (dry configuration).
• Select Automatic level Measurement mode to accept the
sensor measurement of the Level, while you assign a
volumetric value to each custom point (wet configuration).
• Enter from 3 to 10 custom points to link level and volume
values.
• The first custom point must be the lowest fluid level in the
vessel. Each successive point must be greater than the
preceding point.
• The last point must be equal to or greater than the highest
fluid level in the vessel.
• A custom point should be located at each transition point in
the vessel shape (for example, at custom point #9, where the
shape changes from a cylinder to a cone).
• The more complex sections should be defined with more
points. Notice that the conical section of the illustration has
been defined by custom points 1 through 9.
• Simpler sections require fewer defining points. Note that the
cylinder requires only custom points 9 and 10.

5.1 Level and Volume Conversion in Custom Shaped Vessels
Pressure to level conversion:
Level = P ÷ (SG × D)
where P = Pressure
SG = Specific Gravity of fluid
D
= Density of water
With pressure in psi:
Level (meters) = 0.703069 × (P/SG)
With pressure in bar:
Level (meters) = 1.019715 × (P/SG)
Mass Conversion
m = D × SG × V
where m = mass of fluid
D = density of water = 1000 kg/m3
SG = Specific Gravity of fluid
V = Volume of fluid (m3)
m (kg) = 1000 × SG × V
Horizontal cylinder:
V = A × L
where A = area of segment
L = length of vessel
Level, volume and mass calculations performed by the 8250
include:
Vertical cylinder:
V = π× r2 × h
where r = radius of cylinder
h = height of fluid
Rectangular vessel:
V = w × L × h
where w = width
L = length
h = height

5.3 Relay Operation
Relay outputs can be used as switches that respond when the
process variables move above or below setpoints, or when the
process variables move outside of a window.
• The relays may be turned Off if not in use.
• Response can be delayed up to 6400 s ( see Calibrate menu).
Low:
Relay is energized when process variable is less than the
setpoint. The relay de-energizes when the process variable
moves above the setpoint plus the hysteresis value.
High:
Relay is energized when process variable is greater than the
setpoint. The relay de-energizes when the process variable
moves below the setpoint plus the hysteresis value.
Window:
Relay is energized when the process variable moves above or
below a fixed window of values. The relay de-energizes when
the process variable moves inside the window by more than the
hysteresis value.
Note: Relays will operate in reverse if miswired. Observe relay
logic appropriate to the application.
6. VIEW Menu
• During normal operation, the ProcessPro displays the VIEW menu.
• To select a display, press the UP or DOWN arrow keys. The display selections scroll in a continuous loop.
