  • Page 16: Transit-Time Method

    The transit time technique uses a pair of transducers, with each transducer alternately sending and receiving coded ultrasonic signals through the fluid. Figure 2 below shows the paths used in the Sentinel LNG. When the fluid is flowing, signal transit time in the downstream direction is shorter than in the upstream direction; the difference between these transit times is proportional to the flow velocity.

  • Page 17: Multipath Design

    Flow Ranges Typical flow rates for 0.5 m (19.6 in) per second and 10 m (393 in) per second are listed below. The Sentinel LNG is a full bore meter and the flow range is a function of the pipe and not the meter itself.

  • Page 186: Flowmeter Software Setup

    Flowmeter Software Setup Sentinel LNG’s require no special setup procedures by the user. The meter automatically configures itself for HART communication on startup. The analog output must be on, and the mode must be set to the desired state. See [I/O], analog output menu.

  • Page 187: Host Interface

    Analog Output The Sentinel LNG is equipped with a single 4-20 mA output, which can be configured using software to supply 24-volt power internally (active), or to regulate current from an external source (passive). When set to either mode it will support the HART communication channel.

  • Page 211: E7: Analog Output Error

    This message indicates a density input error. Cause: The density exceeds the specified limits for the analog inputs, or no input device is connected. Action: Check the density input device and the connecting cable. Recalibrate the analog input. Sentinel LNG User’s Manual...

    (see Activating a Channel/Path (Status) on page 43). Displaying Diagnostic Parameters The Sentinel LNG offers built-in Diagnostic Parameters to aid in the troubleshooting of transducer and/or electrical problems. To access these parameters, do the following: From the display screen, press [ESC].
  • Page 213 <50 or >75 Signal Dn Displays signal strength for the downstream transducer. 50-75 <50 or >75 Displays the value at which Sentinel LNG detects signal arrival time for the upstream transducer. Thresh Up [%] -100 - +100 <-100 or >100 Displays value at which Sentinel LNG detects signal arrival time for the downstream transducer.

  • Page 214: Fluid And Pipe Problems

    The fluid must be homogeneous, single-phase, relatively clean and flowing steadily. Although a low level of entrained particles may have little effect on the operation of the Sentinel LNG, excessive amounts of solid particles will absorb or disperse the ultrasound signals. This interference with the ultrasound transmissions through the fluid will cause inaccurate flow rate measurements.

    Transducer Problems The Sentinel LNG transducers are rugged, reliable devices that do not come into contact with the process fluid. An engineered epoxy with the appropriate physical and acoustic properties holds the transducer in place. If erratic or...
