The interpretation of the bits and the transformation into a decimal numeric value (integer or comma) or
in a sequence of states (for example coil) depends on the setting of the type of data performed during the
configuration of the variables themselves.
By performing a type change, unfortunately, the interpretation of the old saved data cannot be performed
correctly. For this reason, before changing the variable settings, it is important to download the data saved
on the
KAPTOR
MINI
memory in order to guarantee correct interpretation and saving. Also due to this,
EasySetup displays a reminder requesting even if you intend to delete the historical data.

RS485 flow
The Firmware version called Flow, allows communication on the RS485 port with specific sensors supplied
by B.M. Tecnologie Industriali.
It is possible to select the type of sensor connected to the port and customize its settings.
Sensor type
: choose the type of sensor connected (Doppler
or TTFM) and press
“
Settings
”
for complete configuration.
Warm up time
: it is the awakening time, expressed in
seconds, necessary for the sensors to provide a valid
reading after receiving the supply voltage. The warm up is
significant in the discontinuous operating mode, when the
power is supplied only for the time strictly necessary for
reading.
You can choose from a list of predefined values.
To avoid an unnecessary power consumption, sel

12.1.2.1
Doppler Sensor
The insertion or wedge type doppler sensors allow to measure the flow rate in closed pipes and in
channels of any geometric shape, even of large dimensions.
The measuring principle is based on the reflection of ultrasound by suspended particles.
It is therefore absolutely necessary that there are particles in the water that reflect ultrasound to the
sensor.
The flow calculation is performed by combining the information relating to the velocity of the fluid, the
level value and the geometry of the channel.
