Abstract: A tool for holding and applying torque to a nut including a keyway. The tool includes a longitudinal body having a longitudinal axis and a body channel. A longitudinal key is disposed in the body channel with one end of the key configured to engage the keyway of the nut. A first key portion contacts the body channel while a second key portion extends over the body channel forming a gap between the key and the body channel prior to insertion of the key into the keyway of the nut. The second key portion is configured to be resiliently deflected radially inward toward the longitudinal axis of the longitudinal body when the second key portion engages the keyway of the nut.

Abstract: An apparatus configured for insertion into a sensor port of a flow cell is described herein. The apparatus includes an insert body, a sensor located in the cavity of the insert body, and an insert body holding nut and a sensor holding nut threaded to the interior surface of the sensor port.

Abstract: An insert apparatus for installing a transducer assembly in a sensor port of a flow cell is disclosed. The transducer assembly is installed in the cavity of the insert body without the use of glues or adhesives to bond the transducer assembly to the cavity.

Abstract: An apparatus and method for installing or removing a cable is disclosed. A cable tool includes a cable channel with two channels having different channel openings for receiving or releasing the cable. The first end of the cable channel has a smaller channel opening and an arm that can be used to remove the cable and disconnect a connector on the end of the cable from a sensor.

Abstract: A flow cell for a plurality of sensor assemblies to communicate with a flow meter for measuring characteristics. The flow cell includes a sensor body with a sensor body bore extending through the sensor body. The flow cell also includes a sensor body quadrant extending outwardly from the sensor body bore on a side of the flow cell, wherein the sensor body quadrant intersects the sensor body bore. A plurality of sensor ports extend through the sensor body quadrant to provide openings from the exterior of the flow cell to the sensor body bore in which sensor assemblies can be inserted. A cable channel extends internally within the sensor body quadrant at least from the plurality of sensor ports to an access port on the exterior of the flow cell for routing cables from the sensor ports to communicate with the flow meter.
