Pressure transmitter installation in a process line of a process facility
First Claim
1. A pressure transducer assembly for measuring the pressure in a process circuit of a process plant, said pressure transducer comprising:
- a flow control unit having a housing with a valve chamber, said valve chamber having an inlet and an outlet;
said inlet of said valve chamber in communication with said process circuit;
a valve member carried within said valve chamber, said valve member having an open position for allowing flow from said inlet of said valve chamber to said outlet of said valve chamber, and a closed position for preventing flow through said valve chamber;
a pressure cell disposed adjacent said outlet of said valve chamber;
a closed pressure circuit defined from the valve inlet, said valve chamber, and the valve outlet;
a pressure sensor disposed in said pressure cell for measuring the pressure of said process circuit communicated through said closed pressure circuit when said valve member is in said open position.

Abstract
A flow control unit having a housing with a valve chamber. The valve chamber has an inlet and an outlet. The inlet of the valve chamber is placed in communication with the process circuit. A valve member is carried within the valve chamber. The valve member has an open position for allowing flow from the inlet of the valve chamber to the outlet of the valve chamber, and a closed position for preventing flow through the valve chamber. A pressure cell is disposed adjacent the outlet of the valve chamber. A closed pressure circuit is defined from the valve inlet, the valve chamber, and the valve outlet. A pressure sensor is disposed in the pressure cell and traverses the circuit at the outlet for measuring the pressure of the process circuit communicated through the closed pressure circuit when the valve member is in the open position.
