i have used level transmitter in starch cooking preparation tank. tank total height 2mtr.sometime LT display shows some error value when tank is fully empty and diaphragm side i already checked okay no problem in diaphragm area. field cable checked 24volt and mA shows correct value while tank empty mA is 4mA. 4mA i needed that 0% but display showing 10% or 15% percentage values are varying continously
please give any good solution for me.....

The issue you're experiencing with the level transmitter may be due to one of the following reasons:
1. Sensitivity adjustment: The sensitivity setting of the level transmitter might need to be adjusted based on the tank height and empty/full levels. This can cause discrepancies in the readings, especially when the tank is fully empty. Consult the manufacturer's manual or contact the supplier for guidance on making these adjustments.
2. Calibration: If the level transmitter has not been properly calibrated, it may display incorrect readings, particularly at the minimum levels (tank empty). Check that the transmitter has been calibrated according to the manufacturer's instructions and repeat the process if necessary.
3. Wiring or connection issues: Ensure that all wires and connections are correctly connected and secure. Check for any damaged or corroded wires, as well as any loose or broken connections that may be causing intermittent readings.

What is full form of hart communicator?
What is the purpose of bypass valve across AS valve.
what is vfd(variable frequency drive)?type of vfd.
what is the difference between(Flame proof/Explosion proof)& Fire proof instruments.Both are same or different & if different in which way because the transmitter which have approved ATEX flame proof enclouser but it use PTPE O ring & PTFE Head Gasket,so its (fire safe/fire proof)????????
what is ILD
In control valve there are two type of valve seat we can use metal to metal seat & soft seat.On this valve seat i have following doubt. 1)I have never seen practically the internal assembly of valve so my doubt is that basically weather the seat is soft seat or metal its basic MOC is same as valve body(SS or CS) only in soft seat we are using PTFE ring & place on valve seat & in metal this PTFE ring is not threr am i correct??????? 2)what are the common general rule for using metal to metal seat & soft seat,means its depend on process parameter like liquid,gas, steam & on valve leakage class.
if i want buy a pressure gauge then witch parameter i look
in any transimitter (flow/level) there are three terminals for supply& test (+,-,+)in two wire,24VDC given to Tx.,but how 4-20 ma signal travels thru same wire (as it is for 24VDC input supply)?
How can I map a tank? Tank 15m h and 42m dia. we just fixed radar type lit. its reading shows over range. Now its required mapping ?
any body tell me ,contol valve has how many cheractristic? explain it.
open tank and close tank leavel transmiter about range and calibration
