Codes of Practice 492 and 495 or comparable technical regulations) on the
basis of their training and experience in the sector of energy and gas
distribution.
1.7 Intended use and field of application
This product is intended to be used for the calibratable volumetric metering
of
flammable gases: natural gas/propane/butane
non-flammable gases: air/nitrogen/inert gases
Other areas of application or media, see Annex C –List of gas types or
on request
NOTE!
The hydrogen content of gas mixtures must not exceed 10%.
This product is not intended for
metering aggressive gases, e.g. biogas or sewage gases, oxygen or
acetylene.
1.8 Legal declarations
The metrological conformity assessment is based on the regulations of
the country concerned, in which the measuring instrument will be used.
The period of validity of calibration is based on the regulations of the
country concerned, in which the measuring instrument will be used.
1.9 Recycling and environmental protection
Honeywell has designed the transport packaging of the measuring
instrument to be environmentally friendly. Packaging materials are always
selected consistently with a view to recycling. The cardboard items used
constitute secondary raw materials for the paperboard and paper industry.
The Instapak® foam packaging is recyclable and can be reused.
Plastic sheeting and strips/bands are also made of recyclable plastic. At
Honeywell, subsequent recycling and disposal are already elements of the
product development process. When selecting the materials, we allow for

Honeywell
730xxxxxe © Elster GmbH | All rights reserved. Subject to modification 13
English
reusability of the materials, suitability of materials and subassemblies for
dismantling and separation, and the risks of environmental pollution and
health risks when recycling and dumping on landfill sites. The measuring
instruments mainly consist of metallic materials which can be melted down
again in steelworks and metallurgical plants and which can thus be reused a
virtually unlimited number of times. The plastics used are listed in Annex B
to ensure that the materials can be sorted and separated for the purposes of
subsequent recycling. Like all mineral oils (e.g. for motor vehicles), the oil
supplied with the device must be disposed of in an environmentally sound
way.

2. Structure and function
Operating principle
Rotary gas meters are volume-measuring devices for gaseous media which
operate according to the positive displacement principle. Due to their
volumetric measuring principle, their functioning is not influenced by the
installation and they are therefore ideal for compact measuring systems
without an inlet section. They record the gas volume at operating conditions
and are approved for custody transfer applications. Electronic volume
conversion devices can be used in order to convert the volume.
Measurement procedure
Two rotating impellers which look like a figure of eight when viewed in cross-
section are mounted in a single housing with one inlet and one outlet (see
Fig. 1). The two impellers are coupled together using synchronizing gears.
When gas flows, the impellers rotate without touching one another and
propel a gas volume to the outlet which is defined by the cyclic volume. One
rotation of the system thus corresponds to a defined gas volume. The
revolutions of the impellers are transferred to the mechanical index via a
reducing gear and a magnetic coupler. The rotary gas meter is adjusted
using a pair of gears in the index.

SxD index:
Indexes S1D and S2D feature two roller indexes. A hinged plate covers one
of the roller indexes and at same time shows the flow direction.
Changing the flow direction:
Unscrew the two front screws.
Fold the plate down.
Resecure the plate with the screws.
2.3. Temperature test points
A maximum of two temperature sensors may be used to measure the gas
temperature in the meter housing (see Fig. 5).
If no temperature test points are provided in the meter housing, external
temperature measurements must be taken in the pipe downstream of the
gas meter at a distance of up to 3 x DN, but max. 600 mm away.

NOTE!
In outdoor measuring systems, the result of measurement may
be influenced by the ambient temperature.
Insulate measuring elements outside the pipe adequately to
prevent ambient temperature influences.
Fill the thermowell(s) with a heat-conductive fluid or paste to
achieve optimum thermal conduction.
2.4 Pressure test points
A straight male coupling which complies with DIN 2353 is provided on the
meter housing to act as a pressure test point, for example to connect a
pressure sensor. It is marked pm/pr and is designed for connecting Ø 6mm
steel tubes to DIN EN 10305-1 (e.g. steel grade E235) or flexible pressure
tubes from Honeywell.
CAUTION!
Danger to functional safety!
Functional safety and reliability are ensured only if the material
combination of the union component and the pipe are
intermatched.
The straight male coupling must not be connected to pipes
made of stainless steel or pipes made of non-ferrous materials.
NOTE!
Only use original Parker-Ermeto pipe unions.
We recommend that you contact our local Honeywell Customer
Service Centre for conversion work and when installing
additional devices.
