DLC3020f Digital Level Controller

When complete, the torque rate or gain will be correct at the calibration temperature. After finalizing the installation a
zero trim may be needed since a zero shift may take place when installing the device.

Two Point

 

(Bench or Field)

—A Two Point Calibration fully calibrates the device by observing the level/interface at two

points. The two points must be at least 5% of the displacer length apart. All instrument configuration data is needed to
perform a Two Point calibration. Use this method of calibration when the length/interface can be externally observed.

Min/Max

 

(Bench or Field)

—During the Min/Max Calibration torque rate gain and zero are computed by completely

submerging the displacer in two different fluids (one of which may be air or vapor). All instrument configuration data is
needed to perform a Min/Max calibration and must contain the correct values for displacer volume and driver rod
length.

Simple Zero/Span

 

(Field only)

— 

for applications with relatively constant density and temperature conditions. Two

points (separated by at least 5% of the displacer length) are captured in this calibration. Only the displacer length is
needed to perform the Simple Zero/Span procedure. This calibration does not allow the use of Temperature
Compensation

Note

When using Simple Zero/Span the device cannot be temperature compensated for fluids or torque tube. This calibration should
only be used when the temperature and the process density do not change, otherwise an untrimmable error will occur the farther
away your process conditions get from the calibrated conditions.

Two Point Time Delay 

(Field only)

—the Two Point Time Delay Calibration is a two point calibration in which the two

points captured can be taken some time apart. The first point is captured and stored indefinitely until the second point
is captured. All instrument configuration data is needed to perform a Two Point calibration.

Trim Current Calibration

Zero Trim

—Zero trim is an adjustment to the current calibration. This adjustment assumes that the current torque rate

is correct and the PV error is due to a shift in the zero position.

Gain Trim

—Gain trim is an adjustment to the current calibration. This adjustment assumes that the zero point is correct

and the PV error is caused by a torque rate change.

Default Gain

—Default Gain is an adjustment to the current calibration. This adjustment requires you to set the default

gain to the known torque tube rate.
