P11 – TANK TYPE
This register identifies the type of tank application, with respect to the vertical fluid pressure measurement.
Linear:
The hydrostatic head change is proportional to the level change. For example, a cylindrical tank
standing vertically (first tank pictured on page 19) is linear because the change in pressure produced
by the fluid in the tank is proportional to the change in level (or mass).
Non-Linear: The hydrostatic head change is not proportional to the level change. For example, horizontal
cylinder and spherical tanks (other tanks pictured on page 19) are non-linear, because the change in
pressure produced by the fluid in the tank is not proportional to the change in level (or mass). For
Non-Linear Tanks, the Smart Level Gauge discerns between a cylindrical tank with flat ends, a
cylindrical tank with dished ends, and a spherical tank by the settings in the P9 and P10 registers.
Refer to the examples on pages 18 and 19.

P11 Tank Type Identifies type of tank. 0 = Linear/Vertical
1 = Non Linear If P11=0, verify
that P10=0.
STEP BY STEP: P11, TANK TYPE
Step Action Display
1 Gauge should be in the normal Measure Mode. Normal Pressure Display.
Press the PRGM/Enter
→ key.
2
If the lockout is active, the gauge will now prompt for entry of
the lockout code. Refer to “STEP BY STEP: ENTERING A
LOCKOUT CODE (When Prompted)” on page 21.
The PRGM annunciator shows at the top of the
display, and the display shows the register name
“P0”.
Press the Up
↑ or Down↓ keys repeatedly to scroll
to the desired register.
3
The Zero function (Up
↑ and Down↓) will reset the scroll to P0
and allow selection to continue.
Display shows “P11”.
4 Press PRGM/Enter
→ to open the register.
The display shows the current value.
Press the Up
↑ or Down↓ keys repeatedly to scroll
to the desired register value.
5
The Zero function (Up
↑ and Down↓) will reset the scroll to
default and allow editing to continue.
All available choices are scrolled.
6 Press the PRGM/Enter
→ key to accept the desired
value.
The value is accepted, and the register is closed.
Display shows “P11”.
7 Press the Backspace
← key to activate the register
setting and return to Measure Mode.
Normal Pressure Display.
Notes 1. After steps 2 and 3, the Backspace
← key will abort the process and return to Measure Mode.
2. After steps 4 and 5, the Backspace
← key will abort the edit and close the register.
3. After step 6, the PRGM/Enter
→ key will again open the register for edit.
4. During any programming operation, if there is no keypad activity for approximately 1 minute, the
operation is aborted and the gauge returns to Measure Mode unchanged.
