They include explanations and, in some cases, a recommended action. Page Troubleshooting Page F4 Reset Procedure Turn off power if it is currently on.
The prompt: [Clr Active Memory? No] appears at the top of the screen. Note that the prompt switches to [Clr Saved Data? If a previously installed channel is in a "Fault" The direction of the arrow actually represents the direction in which the Receive "window" The number listed to the right of the command code represents the exponent in the meter exponential averaging routine, where the larger the number the greater the digital averaging. In the main menu, scroll to the [Diagnostic Data] menu and select [Test Facilities].
The damping control [MinDamp ] will appear on the command line at the lower left-hand corner of the screen. This line represents the position in time Tn where the flow meter perceives the arrival of the ultrasonic signal. This envelope screen can aid in the diagnosis of Tn errors caused by unusual receive waveform distortion. If this spike is large enough it may interfere with the signal detection routines. Page Site Setup Data Troubleshooting Some menu items are for technical support interpretation only.
This "HF" parameter is the input for a proprietary algorithm that automatically compensates for signal beam blowing, thereby extending the upper flow limit of the flow meter. Page Technical Data Technical data Page Technical data The following typical example explains how to set up HyperTerminal.

The transmitters include a graphic display providing flow rate, diagnostics data and keypad interface to access on-screen software setup menus. Page Applications Access to the Graphic display and keypad setup must be done with cover opened exposing high voltage connections which may cause death or serious injury. Page Theory Of Operation With accurate signal arrival time available, the flow meter can compute the raw flow velocity from the measured upstream and downstream transit times.
Page 26 The shape of this flow profile for fully developed flow is defined by the Reynolds number. Using the liquid temperature input Standard on FUS and the optional user provided pressure input, the measured VoS is then compensated to the value expected for base temperature and pressure conditions i. Page 30 Benefits include highest available precision and enhanced immunity to distorted flow profile conditions. Page 32 The flow meter derives the angle by knowing the fixed position of the sensors, the dimensions of the pipe and the measured transit-time.
Page 33 Reflect mounting automatically corrects for non-axial flow or cross flow since the 2 vectors in a reflected beam are affected in opposite directions, such that the individual cross flow errors cancel each other. For liquids it is advantageous to install the sensor in low pipeline sections, at the bottom of a U-section in the pipeline. For e. Note If the flowmeter is not used according to the specifications, the manufacturer cannot be held responsible for any resulting damage. See figure below.
