1. General

This guide is intended for trained specialised personnel. Therefore, it does

not include basic working steps.

The seal on the energy meter must not be damaged!

A damaged seal will result in immediate invalidation of the factory

warranty and verication. The cables supplied with the meter

must neither be shortened, extended nor changed in any other way.

Legal regulations and operating instructions for the use of energy

meters must be observed!

The installation must only be carried out by a specialist energy

meter installation and electrical company. The personnel must

be trained in the installation and handling of energy meters and electrical

devices as well as the applicable guidelines.

Medium: Water, according to CEN/TR 16911.

If water additives are used (e.g. corrosion protection), the user must

make sure that the corrosion resistance is adequate.

This product is designated (where relevant) as a pressure main-

taining component in the sense of the Pressure Equipment Direc-

tive (PED) and may only be operated as a pressure maintaining

component with temperature sensors suitable for this purpose.

This product is not intended for used as a safety device in the sense of the

Pressure Equipment Directive (PED).

The medium temperature is specied as 5 ... 105 °C (130 °C)

The temperature range depends on variant and nominal size.

The exact temperature range is shown on the type plate.

The encapsulated variant is to be used if condensation is expected.

The operating/ambient conditions are 5 … 55 °C; IP 54/64; 93 % rel.

humidity.

Ambient temperatures below 35 °C have a positive eect on battery

lifetime.

If the ow sensor is insulated with the pipeline, the calculator

must be accessible.

The Software IZAR@Mobile2 is used for reading out data and conguration

and can be downloaded from the Internet under:

https://www.diehl.com/metering/en/support-center/download-center/

Changing of communication relevant parameters can result in

the loss of OMS certication.

2. Transport and storage

Unpacking

Energy meters are measuring devices and must be handled with care. To

protect against damage and soiling, they should only be unpacked imme-

diately prior to installation.

Transport

The transport of the meter is permitted only in the original package.

When sending wireless measuring instruments / components by

air, disable the wireless (place in aircraft mode) before shipping.

3. Installationofenergymeter(g.I)

Depending on the design and application (heat or cooling meter), the

energy meter is installed in either the hot or cold line of the system.

The ow sensor must be installed so that the ow direction matches

the arrow direction on the sensor.

Depending on the version, the ow sensor must be installed in inlet or

outlet. The installation position is displayed in the info loop 3.4 (see

"Information loop (3)" on page 13) and, if necessary, also by means

of a pictogram.

no pictogram

(Installation position

can be set on site,

5.1 on page 9)Inlet Outlet

Calming sections are not necessary before and after the ow sensor.

For systems without temperature mixing, a straight calming section of

3-10 x DN upstream of the ow sensor is recommended.

The meter can be installed in both horizontal and vertical pipe

sections, provided air bubbles cannot collect in the meter.

The ow sensor must always be lled with liquid.

Avoid frost at the meter.

We recommend installing the ow sensor tilted through 45°.

The minimum system pressure must be 1 bar to avoid cavitation.

Make sure the meter is installed suciently far away from possible

sources of electromagnetic interference (switches, electric motors,

uorescent lamps etc.).

If possible install the cables of the ow sensor or temperature sensor

freely suspended (not bundled - aerial eect) with sucient distance

from electromagnetic interference sources.

For medium temperatures from 90°C or for TWater<TAmbient (cooling

meter application or heat meter with cooling tari application) the cal-

culator must be removed and tted at a sucient distance from any

heat sources. A wall holder (optional) or a spacer holder (optional) is

available for this purpose.

Spacer holder Wall mounting

It is recommended that shut-o valves are tted before and after the

energy meter to simplify removing the meter.

The meter should be installed in a conveniently accessible position for

service and operating personnel.

Initial operation is to be carried out and recorded after installation.

4. Temperature sensor

Handle the temperature sensor carefully!

The sensor cables are provided with coloured type plates:

Red: Sensor in the hot line

Blue: Sensor in the cold line

The connecting cables must not be shortened or extended.

The free temperature sensors can be tted so they are directly sub-

merged (e.g. ball valve) or in a pocket tested for conformity for this

sensor type.

Sensors must be installed symmetrically.

English Italiano Dansk Svenska

4.1 Installation in the ball valve with adapter

(coupling set in a separate bag)

Use ball valves with installation option for temperature sensor with thread

M10 x 1.

Preparatory measures

Close the ball valve.

Unscrew the plug screw from the ball valve.

Installation(seeg.II)

1. Place the O-ring from the attached coupling set (type A or B) on the

mounting pin.

2. Insert the O-ring with the mounting pin into the sensor hole of the ball

valve (turn the mounting pin).

3. Position the O-ring in its nal position using the other end of the

mounting pin.

4. Fastening screws

Type A (plastic) - plug the fastening screw onto the temperature sen-

sor.

Type B (brass) - insert the temperature sensor in the fastening screw

and place the sensor in the mounting pin. Press in the dowel pin com-

pletely and remove the mounting pin.

5. Insert the temperature sensor with the securing tting in the ball

valve and manually tighten (2-3 Nm).

4.2 Installation in a pocket

It is recommended that temperature sensors for DN25 rated sizes or

smaller are only tted in new installations such that they are directly

immersed.

This ensures higher measuring accuracy.

English Italiano Dansk Svenska

5. Start-up operation

Once the meter has been installed, the components (calculator, volume

measuring component and both temperature sensors) must be sealed

with a tamper-proof seal and the meter started up by a specialist com-

pany approved according to the legislation.

Check the display for a plausible indication of ow rate and temper-

atures.

5.1 Inlet/outletsetting(optionalexworks)

Optionally, the installation position of the meter can be set in-situ in loop 3

("3.4" on page 13). Consequently installation in the inlet (ow) or outlet

(return) is possible.

This setting must be made prior to initial operation of the meter.

As supplied, the outlet (return) is pre-set and is shown as follows in the

display. Setting and number of possi-

ble changes.

To changeover, switch to the "Outlet" window in loop 3 (see 9. Operation).

Pressing and holding the button for > 6 s changes the display/setting to

"Inlet".

This setting can be changed a total of 8 times by pressing the button.

The display changes during the 6 s.

This does not inuence functioning.

-10-

English Italiano Dansk Svenska

Sequence during changing

Button pressed <3s Button pressed >3s

If the button is pressed and then held for > 6 s, the meter performs the

command shown in the display. In each change, the framed

number in the display is

reduced by 1.

After 8 changes, it is no longer possible to change the installation position.

The possibility of changing lapses either immediately upon

detection of water, or after three hours’ operation without error

detection (pre-set ex works).

The following indication appears in the display (example):

The changes indication dis-

appears.

When changing the installation position, the sensors must be

matched to the actual installation (see chapter 4).
