Heating / Cooling meter PolluStat E
Installation and operating instructions
1. Important directions
The installation of PolluStat E requires
adequate professional knowledge and
should be carried out by specially trained
persons only.
The technical data specified in chapter 2
must not be exceeded during operation.
The connection cable between flow
sensor and calculator must not be cut,
shortened or extended.
During the installation of PolluStat E, the
well or ball valve, particular care is to be
taken that they are perfectly mounted,
because otherwise there might be the
danger of being scalded by leaking
heating liquid. Therefore, first of all, the
stop cocks are to be closed before
removal.
Depending on manufacturing conditions
the brass connection threads might be
sharp-edged. Therefore we recommend
wearing protection gloves.
Heating or cooling meters are measuring
instruments and have to be handled with
care. In order to protect them against
damages and soiling they should only be
taken from the package immediately
before installation.
The instrument must not be carried by the
cable.
For cleaning purposes use nothing else
but a cloth moistened with water.
Within the instrument there is a battery,
which must not be opened by force, come
into contact with water, be short-circuited
or exposed to temperatures exceeding
80 °C.
Empty batteries, no longer needed
electronic instruments or components are
hazardous waste and to be disposed of at
suitable collecting points.
If several meters are used in the same
billing unit, equal instrument types should
be chosen in the interest of the fairest
possible consumption billing.

4. Installation of sub assemblies
Depending on the version PolluStat E can be
used as a heating meter, as a cooling meter or as
a combined heating / cooling meter. Therefore the
text hereinafter includes following terms:
return pipe of heating plants: colder line
supply pipe of heating plants: warmer line
return pipe of cooling plants: warmer line
supply pipe of cooling plants: colder line
In case of meters with programmable
installation place (see related inscription at
integrator) of the flow sensor the required position
(colder line or warmer line) has to be defined.
In order to do this, activate the display by
depressing the red key and releasing it again.
Then each one of the below mentioned options
can be selected one after the other by a short
keystroke. Having set the required position,
remove the bridge between terminal 3 and 4 in the
terminal block.
colder line warmer line
Attention!
Because of legal calibration regulations the
installation place can only be programmed
once. Therefore be very sure that you have set
the desired position before removing the
bridge.
M H 4110 INT PolluStat E, page 3
4.1 Flow sensor
Applicable standards: EN 1434-6
Standard installation of the flow sensor is in the
heating return pipe i.e. the colder line. If the flow
sensor is to be installed in the heating supply pipe
i.e. the warmer line, the integrator PolluStat EX is
to be used (X means that the integrator has been
adjusted for flow sensors in the warmer line).
An arrow on the body shows the flow
direction. The maximum operating pressure and
the maximum operating temperature must not be
exceeded.
It is absolutely advisable to install a dirt trap
before the flow sensor or at another suitable point
of the heating or chilling circuit as well as shut-off
valves before and after the flow sensor (in order to
avoid having to empty the pipeline if the meter is
to be exchanged). During initial installation a spool
piece is installed instead of the flow sensor and
the pipe system is thoroughly flushed. Then close
the shut-off valves, remove the spool piece, clean
the sealing surfaces and install the flow sensor
using new gaskets. Take care not to reduce the
pipe diameter by bad positioning of the gaskets,
particularly if flanged versions are installed.
In areas with thermal layering (e.g. after the
junction of two pipes with different temperatures)
a straight pipe of 10 x DN in front of the flow
sensor is recommended.
Special direction for horizontal installation of
meters of DN 50 to DN 100:
Both ultrasonic transducers in the flow sensor
have to be in horizontal position. For this reason
the PolluStat E has to be installed with the
integrator turned upwards.
In case of removed and separately mounted
integrator this is valid accordingly.

M H 4110 INT PolluStat E, page 4
Heating / Cooling meter PolluStat E
Installation and operating instructions
4.2 Installation of temperature sensors
PolluStat E is operated with separately approved
and paired temperature sensors type Pt 100 or
Pt 500. The applicable type is specified on the
integrator frontside. The two temperature sensors
can optionally be mounted in thermowells or
directly into the heating or cooling liquid. We
recommend using pairs of thermowells or ball
valves in order to facilitate future exchange.
For a general installation standard please refer to
EN 1434-2.
For temperature sensor type 45 mm x 5.2 mm
(length x diameter) and DS 27.5 acc. to EN 14342 we recommend the installation in our ball valves
with temperature sensor retainer M 10 x 1 or
complete installation kits including fitting pieces
and thread connections (please refer to data
sheet LH 4110 INT).
For Sensus temperature sensors of the overall
lengths 100 mm and 150 mm, the sensitive zone
is ca. 10 to 15 mm measured from the
temperature sensor’s tip and has to be positioned
as near as possible to the middle of the pipe
diameter. Refer to the following guide for
installing such temperature sensors:
Nominal sizes < DN 80*:
Mount the temperature sensors in an angle of 45°
towards the flow direction (see fig. 4).
Nominal sizes > DN 65*:
Mount the temperature sensors at right angle to
the flow direction (see fig. 5).
* For DN 65 and DN 80 both positions are permitted.
For DN < 50 an installation in a bent tube is also
possible.
Fig. 4: Exemplary diagram
for nominal size DN 50
Fig. 5: Exemplary diagram
for nominal size DN 100
4.3 Mounting of the integrator
PolluStat E is delivered with the integrator
mounted on the flow sensor. Depending on the
flow sensor’s installation (horizontal or vertical)
the integrator can be turned through steps of 90
degrees. Lift the spring catch with a screw driver
and take the integrator from the carrier plate.
Then turn the integrator to the required position,
adjust it to the bottom edge of the carrier plate, lift
the spring catch, attach the integrator onto the
carrier plate and release the spring catch.
If liquid temperatures exceed 90°C the
integrator has to be mounted separately, in
order to avoid damages of electronic parts.
Unscrew the carrier plate from the flow sensor,
and fix it at the required place using the two
screws and the two enclosed dowels. Then attach
the integrator as specified above.
4.4 Connection of temperature sensors
The applicable temperature sensor type is
specified on the frontside of the integrator casing.
The required minimum distance from sources of
electromagnetic interference (generators,
frequency converters, ...), as well as from cables
carrying > 230 V, is 0.3 m. Two-wire or four-wire
connection is possible (to extend the length of the
temperature sensor cables by max. 23 m,
recommended cable type I-Y(St)Y 2x2x0.8,
minimum core size 0.5 mm²). Allocation as
follows:

Installation and operating instructions
6. Functional test, sealing
Having opened the shut-off valves, test the
installed units for leaks. For checking purposes
the current values of flow rate, heating resp.
cooling power as well as temperatures of warmer
and colder line can be called to the display
according to chapter 5.1. In order to protect the
meter against tampering, the delivered selflock
seals have to be attached to the following points:
unions of the flow sensor
insertion points of the temperature sensors
lid of the integrator (pull the sealing wire
through the lug at the bottom edge)
7. Possible error situations
PolluStat E is equipped with an automatic selfchecking function. As soon as an error is
detected, the display shows a four-digit error code
„Err XYZW“, which can be decoded as follows:
X: Checking the temperature sensors
Y: Checking the integrator
Z: Error statistics
W: Checking the ultrasonic measuring circuit
The following error message can appear, if – due
to insufficient venting of the pipe – there is air in
the flow sensor disturbing the ultrasonic signals.
Err 00 x 2
Here „x“ stands for a figure from 1 to 9 or for a
capital from A to F.
This error message can also appear on the
display of new heat meters, when – due to logistic
reasons – the flow sensor has not been filled with
water. This is no reason for a complaint because
such an error message will vanish after correct
installation of the meter.
If nominal flow rate is exceeded by more than
130 %, following error message is displayed:
Err xxx4
After reducing the flow, this message will
disappear.

the warmer line drops by 3 K or more below the
temperature in the colder line.
In case of all other errors situations please inform
our service department.
8. Standard interfaces and optional
modules
PolluStat E is equipped with following interfaces
and can have the following optional equipments:
8.1 Optical interface
All meters are equipped with a standard optical
data interface. Via optical data coupler (e.g. order
number 04410230 for RS 232 connection or order
number 184023 for USB connection) settings can
be changed with the service software MiniCom, or
the meter can be read out via the readout system
DOKOM Mobile. The data interface is activated
for one hour by a short keystroke. Every data
communication causes this period of time starts
again, so that e.g. a logger readout at 15-minute
or hourly intervals is possible over a long period of
time.
8.2 Mini-Bus interface
The Mini-Bus interface is standard equipment and
is available at terminals 51 (signal) and 52 (earth).
It is suitable to connect the meter with an
inductive readout point (MiniPad) or other reading
and transmitting instruments (e.g. radio
transponders). The total length of the two-wire
cable between the meter and the readout point
must not exceed 50 m. The communication
M H 4110 INT PolluStat E, page 11

of the supplied cable tie strain relief. The veins at
the corresponding connecting terminals and the
rubber molding back.
8.10 Optional integrated data logger
If this option is incorporated, the casing lid is
additionally labeled with the word „Data Logger“.
The integrated data logger stores consumption
values and instantaneous values (heating resp.
cooling power, flow rate, temperatures) during a
selectable time interval ( 3 to 1440 minutes). The
logger data can be read out via the optical
interface, M-Bus or Mini-Bus with the service
software MiniCom. The time interval (preset in
factory to 60 minutes) can also be changed with
MiniCom.
For PC connection use either an optical data
coupler (see chapter 8.1) or a USB plug-in module
(order number: 68504688).
8.11 Combined heating / cooling meter
Descriptive name: PolluStat E H or PolluStat EX H
This PolluStat E version switches over at an
automatic switch-over point between metering
heating and cooling energy. The switch-over point
to cooling energy is preset in the factory to:
supply flow temperature < 25 °C and
negative temperature difference > - 0.15 K
Conditions to switch back to heat metering:
supply flow temperature > 25 °C and
positive temperature difference > 0.15 K
If required this switch-over point can be changed
on site with the service software MiniCom.
