‘DEFAULT’ the delay time must be set within this option.
● This delay time (DELA) will be activated at any time if the transmitter
cannot find or measure the level. The delay time should be selected
in respect to the process conditions eg: a short alarm time for a fast
process control.
With the 8175 level transmitter it is additionally important to select the type of filter
depending on the application. In some cases where a vessel is closed, echoes can be
rebounded from the top of the vessel producing a ‘doubling’ effect. The ‘CLOSED’ filter
function ensures the filtering of this interference. If the filter is insufficient for the
application the ‘DOME’ filter can be used.
If the measurement is not ‘doubled’ or a precise detection and filtering of close
objects is required select the ‘OPEN TAN’ filter.
