Claim:
1. An isolator system for a pressure transmitter, the system comprising: a port internal to the transmitter; a sensor tube connected to the port to fluidly connect a passageway through a transmitter body to a pressure sensor, the sensor tube including a first end disposed in the port, the first end having a first cross-sectional area, said first cross-sectional area being perpendicular to a longitudinal axis of the sensor tube; and a fill tube internal to the transmitter, the fill tube connected to the port to fluidly connect to the passageway, the fill tube including a second end disposed in the port, the second end having a second cross-sectional area, said second cross-sectional area being perpendicular to a longitudinal axis of the fill tube, that is less than the first cross-sectional area of the sensor tube, wherein the first cross-sectional area is between 60% and 90% of a sum of the first cross-sectional area and the second cross-sectional area.
