HML 210 FLOW RATE VISUALIZATION The HML 210 can to show a 5 digit character display for flow rate units; this mean the maximum flow rate value that can be represented on the display is 99999 (no matter the positioning of the decimal point). The minimum is 0.0025. The representable measure unit depends from sensor flow rate and diameter; the permitted units are those, set the instrument full scale value, allow to be represented with a numerical field which the maximum value do not exceed 99999.

HML 210 (POS. 3.2) Measure filter [M. filter=s XXX.X] This section of the manual is extremely important because the right settings of filters allow to get a proper meter reaction according to the flow rate behaviour. WORKING PRINCIPLE There are two filters: MFSLN (Measure Filter Slow LeNght): available via ETP and through the display, in menu 3. Measure, function “M. filter” The M.

HML 210 (POS. 3.5) Automatic scale change enable [Autorange=ON/OFF] Enables the automatic change of scale. The meter may have two different working ranges in order to suit to the variable process conditions. In order to get the best results out of this function it is important range N.2 (Fs2) if enabled is bigger than N.1 (Fs1). When the flow rate increases and reaches the 100% of the full scale 1, then the meter automatically switches to scale 2.
HML 210 MENU 5 - INPUTS (POS. 5.1-4) Reset totalizer enable [T/P+/-RESET=ON/OFF] When one of this function is enabled, the related totalizer may be reset through the on/off input. (POS. 5.7) “Autozero” calibration external command enable [Calibration=ON/OFF] When this function is active, applying a voltage on the on/off input terminals the meter performs a autozero calibration cycle. ATTENTION: If the voltage pulse is less than 1 sec.
