Differential Pressure Transmitters
Advanced Transmitter Differential Pressure Transmitters (GTX**D series) are used to measure the flow rate of gases, liquids, and steam, to measure tank fluid levels, etc. They provide high accuracy of ±0.04 % together with long-term stability (zero drift of only ±0.1 % over 10 years), greatly reducing calibration work after installation.
Other models measure minute pressure differences as low as 0.1 kPa, or withstand pressures as high as 42 MPa.
