1 Introduction
1.1 Intended use
The flow meter can be used to display flow volumes of sample gasses or liquid mediums. Please refer to the nameplate to
identify your model. In addition to the job number it also contains the item number and model designation. Any special features applicable to a flow meter model are described separately in the operating manual. When connecting, please note the specific values of the flow meter, and the correct version when ordering spare parts.
SM-6/SM-6-V series flow meters can also be equipped with a bistable limit switch. On the SM-6-V the flow volume can be adjusted with the needle valve.
On S-SM series safety flow meters the actual metering glass is protected by a second, thick-walled glass cylinder. If the metering
glass bursts, the outer glass cylinder resumes protecting so medium cannot leak. A stainless steel tube further protects this
outer glass cylinder from mechanical damage. Please refer to the data sheet for the various S-SM models.
NOTICE When used in explosive areas
Model SM-6, SM6-V and S-SM 3-1 flow meters meet the fundamental safety requirements of Directive 2014/34/EU and are therefore suitable for use in Ex areas (

avoided.
Signal word for a hazardous situation with low risk, resulting in damaged to the device or the property or
minor or medium injuries if not avoided.
Signal word for important information to the product.
Warning signs
These instructions use the following warning signs:
Warns of a general hazard Wear respiratory equipment
Warns not to inhale toxic gasses Wear a safety mask
Warns of corrosive liquids Wear gloves
Warns of explosive areas
2.2 General hazard warnings
The equipment must be installed by a professional familiar with the safety requirements and risks.
Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent
malfunctions and avoid personal injuries and property damage.

The operator of the system must ensure:
– Safety notices and operating instructions are available and observed,
– Inspections prior to initial operation and routine inspections according to the Ordinance on Industrial Safety and Health (Be-
trSichV) are performed,
– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
DANGER Toxic, acidic gasses
Sample gas can be harmful.
a) Switch off the gas supply before performing maintenance and, if necessary, flush the
gas lines with air.
b) If necessary, ensure a safe gas discharge.
c) Protect yourself from toxic / acidic gasses when performing maintenance. Wear ap-
propriate protective equipment.

DANGER Application in explosive atmosphere
Combustible gases and dust may inflame or explode. Avoid the following hazardous
situations:
Electrostatic charge (spark formation)!
Clean plastic parts and labels with damp cloth only.
Connect metallic housings to ground!
Maximum surface temperature!

Ignition temperature!
Regard the ignition temperature of the explosive gas-atmosphere as well as maximum
allowable surface temperatures (regard directive 94/9/ EC and harmonized standards).
Risk of breakage / emission of explosive or toxic gas possible.
Protect the equipment against being hit.
Gas leakage!
