how to calibate level transmiter ?range -150 to +150.what is the zero and span?..

Answer / sam

This means that your transmitter is capable of measuring a
differential pressure of 300. Whatever this units of measure
is. You can calibrate the transmitter for any of the
following conditions:
LRV = -150 = 0%
URV = +150 = 100%
Therefore span = 300 UOM (units of measure)
or
LRV = 0 = 0%
URV = +150 = 100%
Therefore span = 150 UOM (units of measure)
or
LRV = -150 = 0%
URV = 0 = 100%
Therefore span = 150 UOM (units of measure)
or
You can also calibrate the tx for any span in between this
300 range.
To find the correct Z/S values for your application measure
the distance from the transmitter to zero position on the
vessel and multiply this with the density of the product you
want to measure (LRV). Do the same with your 100% (URV) value.
Good luck
