Indicator Adjustment

Following are the three universal procedures for indicator adjustment:

Fill the tank with actual liquid and calibrate the indicator to measured volume.

With the tank empty, calibrate the indicator using formulaic calculations.

Fill the tank with water and calibrate the indicator to measured volume.

Note!

After removing the cover, the indicator can be removed by pulling it outward. Align and insert the indicator, 
using calculated value.

4.3.1

Calibration Using Actual Measuring Liquid

After filling the tank halfway with liquid, the indicator calibration should be performed. This is the ideal level 
for calibrating indicator. Calibration is possible, however, whether tank is low or filled to capacity.
In order to obtain a reliable value, measure the liquid level two or three times, using a measuring tape which 
has been officially tested accurate to within ±0.3 mm/m (±1.2mm/10 m). Calibrate to the values only after 
accurate data has been gathered.

4.3.2

Calibration through Calculation for Empty Tank

1.

When the tank is empty, calculate the liquid level Lƒ using the following formula and set indicator to the 
determined value.

2.

When liquid reaches to the value of Lƒ, the float gains buoyancy and LTC will show proper liquid level.
