13. Empty level In some circumstances the Gauger might detect an echo which is further out than the Empty level This echo may be the result of the actual target below the empty level or a strong interference below the empty level In such cases Gauger would report Empty and would transmit an SMS to report the event If you expect echoes further out than the empty level and you prefer to avoid these event reports you can define a Far Blocking Distance FBD Once defined the Gauger will completely disregard any echoes beyond the FBD If no other echoes closer than FBD are detected the Gauger will report lost of echo The default for Far Blocking Distance is identical to the distance to maximum range of the Gauger Gauger420 User Manual page 56 of 69 Jan 2012 Rev 1 12 e Near blocking distance If distance between the sensor face and the topmost level of the target is larger than the specified dead zone by at least 5cm you should consider defining a Near Blocking Distance NBD The NBD should be defined as 2 3 cm shorter than the distance to the topmost level This will ensure that the Gauger will not measure obstructions slightly above the topmost level and report them as full level Similarly when an extension pipe is used and the length of the extension pipe is larger than the dead zone you should define NBD which is larger by 2 3 cm than the length of the extension pipe This will ensure tha

15. allows you to tune the tracking of Gauger to fast moving targets You should increase the filling rate figure if your target fills up or drains down rapidly Always use the lowest possible filling rate in order to preserve accuracy of the measurement A high filling rate will allow better tracking before lost of echo when the target moves rapidly Nearby full empty levels the tracking rate is reduced to avoid erratic entry into full empty level Gas Velocity Coefficient Distance and level are derived by multiplying the delay of ultrasonic echo by the velocity of the ultrasonic pulse in air close to speed of sound In a gas environment which different than air the velocity of the ultrasonic pulse is also different If velocity in the gas environment is twice as high as the velocity in air a Gas Velocity Coefficient of 2 0 should be configured within the Gauger using the GCOF command Similarly if the velocity in the gas environment is half the velocity in air the GCOF coefficient is 0 5 Speed of sound at different gasses and mixtures can easily be found in physical and engineering textbooks and internet sites HART communications HART is a standard digital communication protocol carried by the two power lines of Gauger420 When using HART communications make sure that the voltage on Gauger420 port is at least 14VDC The protocol can provide information on four different Measurands which may be selected at setup HART may be used as a
