(1) Static accuracy includes the combined errors due to nonlinearity, hysteresis and nonrepeatability on a Best Fit Straight Line (BFSL) basis, at 25ºC per ISA S51.1.
(2) Thermal error is the maximum allowable deviation from the Best Fit Straight Line due to a change in temperature, per ISA S51.1.
(3) For ranges < 23 ft H2O (7 m H2O), output is 0-50 mV.
(4) For ranges < 12 ft H2O (4 m H2O), maximum thermal error is ±0.1% FSO/ºC.
(5) For ranges <= 5 ft H2O (1 m H2O), zero offset is ±0.25 mA.
(6) For ranges > 230 ft H2O (70 m H2O), output is 4-20 mA only.
(7) Optional VDC outputs can be provided up to 2.5 VDC less than the excitation supply voltage.
(8) Intermediate level ranges are available.
(9)  -20ºC to 50ºC for level ranges <= 100 ft (70m) H2O when using ETFE cable.
(10) ETFE is a fluoropolymer (Teflon® derivative) material, Tefzel® or equivalent
