3.2 Construction and operation of TD 32500
The digital indicator is equipped with a programmable measuring input for
flow rate and for summarizing the total volume. The instrument is designed
for use with SIKA flow sensors.
Optionally the measuring instrument can be also equipped with a
measuring input for resistance thermometers Pt100, two Open-Collector
alarm outputs, one TTL frequency divider output and analogue outputs 0/4-
20 mA or 0-10 V.
Depending on set-up, the display views in numerical values the flow rate
of the connected flow sensor, the summarized value of a resettable total
volume, the summarized value of a non-resettable total volume or the
temperature of a Pt100 resistance thermometer.
In addition the flow rate, the resettable total volume or the temperature is
displayed as percentage reading in a bargraph, depending on
programming.
Programming the instrument is carried out with the operating keys and
. These keys are designed as light reflection buttons. You can configure
the instrument with the keys and set it up for the required measuring
function.
The alarm-LED 4indicates overstepping or falling short of adjusted limit
values.
The electronics are dust and watersplash safe installed in the bayonet ring
casing . The casing is installed onto the SIKA flow sensor and can be
rotated by 180°, thus providing through individual adjustment free view to
the instrument.
The electrical connection is completed via a multicore supply cable or a
round multipoint plug-and-socket M12x1, depending on customer

3.3.2 Alarm output As an option, TD 32500 is equipped with two Open-Collector alarm outputs.
These can provide a current of 30 mA for switching a load. This current is
sufficient to switch a power relay of 24 VDC / 1000 Ω. Depending on
programming, with a set-off alarm is the load through the alarm output of
the open-collectorswitched against (working current alarm) or separated
from the supply voltage (closed circuit alarm).
For these alarm outputs, the following settings can be selected, in each
case independently from each other:
1. Alarm source: flow rate, total flow (resettable), or
temperature alarm
2. Alarm type: minimum or maximum alarm
3. Alarm set value
4. Hysteresis of the alarm set value
3.3.3 Analogue output
The TD 32500 is optionally equipped with an analogue output. The
analogue output can be set in the following way:
1. Source of the analogue output: flow rate, total flow
(resettable), or temperature analogue output
2. Type of analogue output: 0-20 mA, 4-20 mA or 0-10 V
3. Range of analogue output
In mode 0-20 mA or 4-20 mA a current is driven through the working
resistance against the negative pole of the supply voltage. The working
resistance must be smaller than 500 Ωif the supply voltage is 12 VDC, and
1000 Ωif the supply voltage is 24 VDC.
In mode 0-10 V a supply voltage of at least 15 VDC is required.
3.3.4 Frequency divider output
TD 32500 is optional equipped with a frequency divider output. The
generated frequency can either be the same as with flow sensor or the
frequency of the flow sensor is divided by a free selectable integer factor.
The frequency divider output is designed as Open-Collector-Output and
switches a maximum load of 200 Ωbetween +5 VDC and 0 VDC.
The programmable deviding rate must be selected in such a way that a
maximum output frequency is kept below 1000 Hz.
3.3.5 Power supply
Power supply of TD 32500 is 12 VDC up to 24 VDC.

Note: Gate time is the period which the instrument TD 32500
needs to measure the flow.
With long gate times is the calculated flow signal very precise but
flow changes prolong response time.
With short gate time is the calculated flow signal more imprecise,
but with flow changes the response is shortened.
Note: If the frequency generated by the flow sensor is below
20 Hz, TD 32500 switches automatically from gate time measuring
process to a pulse-length measuring process. This improves
measuring precision with low frequencies.
The duration of one oscillation period is measured by the
TD 32500 in a pulse-length measuring process. Thus the
response time for flow changes is equal to the duration of one
oscillation.
This is calculated by: tR= 1/fS:
