Feed factor, also known as the fill density or pack density, is a measure of the efficiency with which raw materials are loaded into the cement kiln. It is important in the cement industry because a higher feed factor means that more material can be processed in a given time, leading to increased productivity and lower energy costs.

The feed factor is typically calculated by dividing the volume of solids (cement raw materials) by the total volume occupied by both solids and air within the kiln. The equation is as follows: `Feed Factor = Solid Volume / Total Volume`. To solve for the feed factor, you need to measure the volumes involved and perform the calculation.

BUT ,,, DURING CALIBRATION I SELECT RANGE BY HART LRV IS 900 MMH20 & URV IS 1300 MMH20 ,, BUT ,TANK LEVEL SOMETIMES 100 % AT 1100 MMH20 , SOMETIMES 1300 MMH20 ..IN THIS CONDITION .. WHOLE LOOP FAILED ,, MAIN THING IS THAT ,, HOW TO CUSTOME RANGE SELECT ?? AND IF I USED RANGE OVER THE ORIGINAL CALIBRATE RANGE ,,,THEN WHAT ERROR WILL BE COME ??? HOW TO ZERO CALIBRATION OF DPT... HOW TO ZERO TRIM BY MANIFOLD ?? AND FOR TANK LEVEL PURPOSE ... WHICH UNIT I CAN USE ??? IS THERE ANY CALCULATION OR CALIBRATION .. IF YEH .. THEN PLZ JUST GIVE ME CALIBRATION STEPS FOR DPT.. THANKS YOURSSSSSSS
