20090071252 | ULTRASONIC PROBE HEAD - An ultrasonic probe head, in particular for an ultrasonic flow meter having a housing and an ultrasonic transducer in the housing, wherein ultrasonic signals can be created and/or detected by the ultrasonic transducer and the ultrasonic signals from the ultrasonic transducer can be emitted and/or received via an ultrasonic window. A thin, relatively flexible solid interface layer is provided between the ultrasonic transducer and the ultrasonic window, the surface of the ultrasonic window having contact with the solid interface layer has a specified roughness and the ultrasonic transducer is impacted with a force, wherein the material of the solid interface layer and the ultrasonic window, the specified roughness of the surface of the ultrasonic window and the force are attuned to one another so that the solid interface layer nestles into the ultrasonic window of the housing at least also by plastic deformation. Thus, a passage is created between the ultrasonic transducer and the ultrasonic window that eliminates, at least partially, the known disadvantages between the ultrasonic transducer and the ultrasonic window. | 03-19-2009 |
20110239730 | CALIBRATION DEVICE FOR MASS FLOW METERS - A calibration device for mass flow meters including a test piece measuring section into which the mass flow meter test piece to be calibrated can be inserted, a device for creating a flow of a medium through the test piece measuring section and a temperature-measuring device positioned in the test piece measuring section for detecting the temperature of the medium. The temperature-measuring device is position in the flow such that the flow is disturbed as little as possible, while at the same time being capable of highly-accurate detection of the temperature of the flowing medium. In particular, the temperature-measuring device is an ultrasonic temperature-measuring device that is configured to emit an ultrasonic signal into the medium and determine the temperature of the medium by measuring a speed of the emitted ultrasonic signal. | 10-06-2011 |

20090222699 | Method for Displaying Quality of a Digital Communications Link for Field Devices of Automation Technology - A method for displaying the quality of a digital communications link for field devices of automation technology on a field device serving as a monitoring unit. According to the method telegrams are transmitted via the communications link and are tapped in the monitoring unit and tested according to at least two criteria. The result of the testing is displayed as a bar chart on the monitoring unit, so that the user can observe quality of the communications link simply and easily. | 09-03-2009 |
20110192466 | INJECTION OR OTHER SYSTEM WITH ANTI-THERMAL LOCKDOWN MECHANISM AND RELATED METHOD - An apparatus includes a first valve configured to selectively direct material to first and second outlets and a second valve configured to block the second outlet. The first and second valves define a dead space that has a volume between the first and second valves. The apparatus also includes a pressure compensation unit configured to dynamically provide an additional volume for material trapped in the dead space when the trapped material expands. The pressure compensation unit could include a piston configured to move within a space of the pressure compensation unit, where increased pressure in the dead space causes the trapped material to push against the piston in order to provide the additional volume for the trapped material. The pressure compensation unit could further include a spring configured to bias the piston and a seal configured to substantially prevent the trapped material from passing the piston and contacting the spring. | 08-11-2011 |
20120260717 | SMALL VOLUME PROVER APPARATUS AND METHOD FOR PROVIDING VARIABLE VOLUME CALIBRATION - A small volume prover (SVP) apparatus and method for providing variable volume calibration. The apparatus includes a precision bore cylinder and a piston configured with a valve arrangement in order to permit fluid to pass through an annular passage when the piston is traveling from one position to an opposite position. A position sensor and a pair of optical slot detectors can be integrated in association with the piston for continuously sensing an accurate position and stroke of the piston. The position sensor verifies the optical slot detectors at every run and provides calibration of flexible volumes as the fluid travels via the annular passage. The position sensor also checks the correct return of the piston after the flow stroke and detects the stuck mechanics. Such small volume prover apparatus associated with the position sensor can be employed for precise and fast position sensing of the piston and variable volume calibration of a fluid flow sensor. | 10-18-2012 |
20140039816 | BULK STORAGE TANK MONITORING INCLUDING EVAPORATIVE LOSS ASSESSMENT - A method of storage tank monitoring including calculating liquid inventory within the storage tank. Real-time parameters associated with evaporative loss of a liquid stored within the storage tank are determined to produce input data. The real-time parameters include at least one condition within the storage tank and at least one environmental condition. Evaporative loss is automatically calculated with an inventory calculation algorithm using the input data and at least one known physical property of the liquid in the storage tank. | 02-06-2014 |

20140016126 | SERVO GAUGE USING RAMAN SPECTROSCOPY FOR STORAGE TANK APPLICATIONS - An apparatus includes a servo gauge. The servo gauge includes a displacer configured to be raised and lowered within material in a tank. The servo gauge also includes at least one light source configured to illuminate a sample of the material at the displacer. The servo gauge further includes at least one detector configured to measure radiation that has interacted with the sample of the material at the displacer. In addition, the servo gauge includes an analyzer configured to perform Raman spectroscopy analysis of measurements from the at least one detector and identify at least one characteristic of the material. | 01-16-2014 |
