| Notes: |
| (1) |
Intermediate level ranges are available. |
|
(2) |
Total Error Band (TEB) includes the combined errors due to nonlinearity, hysteresis, nonrepeatability and thermal effects over the compensated temperature range per ISA S51.1. |
|
(3) |
For absolute reference, additional error up to ±0.2% FS/year may be incurred due to offset drift. |
| (4) |
Leve/temperature averaging must be reduced as required. |
|
(5) |
ETFE is a fluoropolymer ( Teflon® derivative) material, Tefzel® or equivalent. |
