4-20 MA, PULSE AND PULSE DIGITAL OUPUT CONFIGURATION
The e-FlowMeter is factory calibrated. Calibration depends on the model and size of the valve (see chapter 4.3 « Flow
Parameters Factory Calibrated » for the corresponding values). But if necessary, it is possible to change the 4-20 mA
scaling or pulse weight and pulse width.
When starting e-FlowMeter Software, the window below appears:
Informations:
Display information: Serial number, Firmware version, calibration units (Metric units in l/s or US units in
GPM), valve model and programming date.
Display unit:
It is possible to change the display unit (l/s, GPM (Gallon Per Minute), GPH (Gallon Per Hour), Ml/d (Mega liter
per day), m

/min et CFS (Cubic Feet per Second) then click "
Write Parameters
".
4-20 mA output:
Allow the 4 mA and 20 mA values to change, then click "
Write Parameters
".
Offset and Gain:
If there are some special applications, use Offset and/or Gain to obtain a better measurement.
Output values:
When "
Dynamic Reading
" is clicked, it shows the frequency measured by the pieozoelectric sensor,
4-20 mA output, flow and volume. To put the volume to 0, click on "
Reset Volume
"
Pulse or digital pulse activation:
If the "
Pulse Mode on Serial Output
" is ticked, the pulse output is activated, if it is
disabled, the digital pulse is activated, then click "
Write Parameters
".
Pulse output parameters:
In standard the pulse output is activated with a Pulse weight of 100 liter for valve size DN 150
mm and below, 1000 liter for valve size DN 150 mm and above. The Pulse Width is 250 ms (millisecond). Both values could
be changed if necessary, then click "
Write Parameters
".
