摘要： A high resolution pulse count interface is situated between a positive displacement (PD) meter and a flow computer. A magnetic wheel attaches to the PD meter, with the interface using Hall Effect sensors to detect the rotation of the wheel. A pulse prediction algorithm and weighting algorithms are used to improve resolution for the flow computer to enable real time flow rate calculations.

摘要： An improved switch point setting device for fluid process sensors monitoring a process pressure, including a cylindrical housing, an elongated threaded shaft rotatably mounted in the housing, and a movable post member with a threaded base portion threadably mounted on the threaded shaft within the housing and a dog-leg post portion extending from the housing to form a pressure set point. A coil spring within the housing biases the threaded base portion in positive threaded engagement with the threaded shaft. An O-ring provided around the base portion on each side of the post portion enables threadable movement of the base portion during set point adjustment while otherwise maintaining the base portion reliably in position.

摘要： An extremely accurate and reliable fluid pressure sensor for monitoring process pressure and sensing when predetermined pressure set points or limits have been reached. A Bourdon tube with a pivotally moving lever end responds to the process pressure. When the process pressure is within the desired pressure range, a fluid operated block and bleed relay is operated to provide a first pressure level at its outlet. As the preset pressure point is reached, the relay is operated to provide a change in the outlet pressure level for actuating suitable safety units. A pivoting beam responds to pivoting movement of the Bourdon tube lever arm about the pressure set points and effectively amplifiers or increases such movement to rapidly operate the relay. Snap-acting cap means with a self-aligning disc cap a nozzle port in the relay in response to pivoting beam movement.
