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

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.

Honeywell

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 upstream of the gas

meter at a distance of up to 2 x DN.



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 6 mm

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 or Voss pipe unions.

 We recommend that you contact our local Honeywell Customer

Service Centre for conversion work and when installing

additional devices.
