Flow sensor with relay or reed switch output
The transmitter is a reed switch, which is normally mounted on vane wheel and Woltmann meters, or relay
output from e.g. MID-meters. This type of transmitter should not be used as the quick pulse input may cause
bounce problems.

Flow sensor with active pulse output, powered by Pulse Tester
This connection is used together with either Kamstrup's ULTRAFLOW
or Kamstrup's electronic pick-up for
vane wheel meters.

Flow sensor with active output and integral supply
Flow sensors with active signal output are connected as shown in
Figure 51
. The signal level must be
between 3.5 and 5 V. Higher signal levels can be connected via a passive voltage divider, e.g. of 47 k
/10
k
at a signal level of 24 V.
Pulse outputs (M1/M2)
Two-wire connection:
Voltage

Load
1.5 k
Three-wire connection:
Voltage
5...30
V
Load
5 k

The outputs are galvanic separated and protected against overvoltage and reversed polarity.
Max. counter capacity before overflow is 9,999,999 counts.
