Abstract: An isolator system for a pressure transmitter includes a port internal to the transmitter, a sensor tube, and a fill tube. The sensor tube is connected to the port to fluidly connect a passageway through a transmitter body to a pressure sensor. The sensor tube includes a first end disposed in the port. The first end has a first cross-sectional area. The fill tube is internal to the transmitter and connected to the port to fluidly connect to the passageway. The fill tube includes a second end disposed in the port. The second end of the fill tube has a second cross-sectional area that is less than the first cross-sectional area of the sensor tube.
