<p>A pressure or flow transmitter (11) having a pressure sensor (27) disposed in a transmitter housing (14). The pressure transmitter (11) includes a diaphragm (18) remote from the pressure sensor (27). The diaphragm (18) is connected to the pressure sensor (27) with capillary tubing (22) containing a fluid. The diaphragm (18) is disposed at a relative vertical position (H) from the transmitter housing (14). The transmitter (11) contains circuitry (58, 60, 62, 64) which provides a transmitter output as a function of the pressure output, the circuitry (58, 60, 62, 64) adjusts the transmitter output as a function of the relative vertical position (H) of the diaphragm (18).</p> |
