  • Publication number: 20060226651
    Abstract: The distal end of a tube is operatively attached to a fluid port of a fluid element with a tamper-proof, non-releasable, push-in, quick connect apparatus having a flangeless collet, in such a manner that the flangeless collet cannot readily be moved with respect to the tube after the distal end of the tube is operatively attached to the port of the fluid element.

  • Publication number: 20060219538
    Abstract: A method and apparatus are provided for simultaneously changing multiple liquid level settings in a liquid-level switch including a diaphragm actuated pressure switch apparatus having a first and a second switch, through use of an actuator apparatus including a single control knob shaft rotatably connected to the pressure switch apparatus and having a first and a second cam fixedly attached to the shaft for rotation therewith, the first cam being operatively connected to provide a biasing force against actuation of the first switch, and the second cam being operatively connected to provide a biasing force against actuation of the second switch.

  • Publication number: 20060180206
    Abstract: A system and method of flow rate compensation is provided to allow precise volume dispensing over widely varied and varying input process media pressure and flow conditions. This system utilizes empirical data of actual flow rate versus flow rate measured by a flow meter to characterize flow meter non-linearities. This data is used to generate a compensation control curve. The system controller receives flow data from a flow meter in the field and calculates pulse duration of the output of the flow meter. The compensation control curve is then used to determine the volume of process media flowing at any given time. This instantaneous volume information is added to an accumulator to determine the volume of process media dispensed. This volume is compared to a target volume. Once this target volume is reached, the flow of process media is stopped.

  • Patent number: 6751978
    Abstract: A transition fitting for directing fluid from a first line into a second line includes a body, an inlet, an outlet, and a channel. The body defines a constant-volume channel that redirects a direction of the fluid entering the inlet. The inlet is connected to the body and connectable to the first line, and the inlet directs the fluid from the first line into the channel. The outlet is connected to the body and connectable to the second line, and the outlet directs the fluid from the channel into the second line. The bracket is connected to the body and at least partially surrounds the body.
