What must be programmed when connecting a flow sensor?
The TD 8250 is set-up for the connected flow sensor.
This is carried out under menu reference
“00 - pulse flow sensor”
, menu reference
“09 -
density”
, and under menu reference
“08”
at the position
“counter input”
.
The pulse volumes for SIKA flow sensors can be obtained from the table.

The “X” characters in the “Input value Menu reference 08“ column are of no significance for the set-
ting up of the flow sensor.
Example:
An VZ0.04 flow sensor is connected. The pulse volume is 0.040 cm
3
. The VZ 0.04 Flow sensor
has a 2 channel layout.
The value 0.040 is entered under menu reference “00“.
A “0” is entered under menu reference “08” at the position designated “counter input”.
Additionally a density factor can be adjusted to indicate the mass.
Density of medium will be adjusted under menu “
09 – density factor
”. For volumetric
measurement density factor has to be adjusted to “
1.000
”.
The impulse volume (cm³/Impulse) of the SIKA turbine flow sensor is shown on the name
plate and on the enclosed test certificate. The pulse rate refers to the rate of 1 litre of the
medium used in the calibration.
The impulse volume is calculated as follow:
1000 ccm : number of pulses / litre = impulse volume (cm³/Impulse)
for example:
1000 ccm : 9854 Imp/l = 0.1014816... (cm³/Impulse)
0.101 has to be entered under menu reference 00.
