2 Safety
2.1 Intended use
The SFTE is intended for detecting the flow of gaseous media in piping systems or
terminals in the industry sector.
WARNING!
Risk of injury from prohibited media.
Use of the product in combination with prohibited media can result in personal
injury.
• Do not use the product with flammable or corrosive gases.
NOTICE!
Product damage due to incorrect air quality class.
Condensation water, oil mist, foreign matter and other dirt in the compressed air
can damage the product and cause incorrect measurements and malfunctions.
• Adhere to the specified air quality class for the operating medium.
2.2 General safety instructions
• The product may only be used in its original status without unauthorised
modifications.
• Only use the product if it is in perfect technical condition.
• Take into consideration the ambient conditions at the location of use.
• Comply with all applicable national and international regulations.
• Do not use the product in combination with inflammable, caustic, vapour-
emitting or other hazardous media.
• Check the operating medium to determine compatibility with the materials it
contacts.
• Observe the specifications on the product labelling.
• Remove all transport packaging. Recycle packaging material.

6 Function
The SFTE detects the flow rate (standard flow rate, mass flow rate) with the aid of
a thermal procedure. Measurements are carried out using a micromechanical
sensor element with a downstream electronic evaluation unit. The connection to
higher-level systems is implemented through a non-linearized analogue output.
The analogue output is calibrated at zero point and at the maximum flow rate
è 12 Technical data. The characteristic curve of the analogue output results from
the raw signal of the sensor element. In addition to a fast response time, the non-
linearized characteristic has the advantage of high sensitivity in the lower flow
range.
NOTICE!
Damage as a result of overflow.
Strong overflow can destroy the sensor element.
• Do not exceed the maximum overflow 12 Technical data.è
• Avoid rapid changes in pressure, which cause impermissible overflow.

The STFE does not detect the flow direction. With a return flow, it issues a voltage
signal with another characteristic curve, which is not calibrated.

7.2 Pneumatic installation
The direction of flow is indicated on the sensor by an arrow.
• Attach both tubings to the connections. Screw on M5F with max. 1.5 Nm.
If the tubing of the SFTE is incorrectly connected, flow rate values are also detec-
ted and issued by the analogue output. The voltage values in the negative flow
direction are not the same as the voltage values in the positive flow direction
è 6.2 Return flow characteristics.
7.3 Electrical installation
WARNING!
Risk of injury due to electric shock.
• For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
• Observe IEC60204-1/EN60204-1.
Long signal lines reduce the resistance to interference.
• Adhere to the maximum permissible cable length of 30 m.
