• II symbol on the back of the flange or Tri-Clamp

Installing in pipes

• Flow velocity up to 5 m/s with a viscosity of 1 mPa⋅s and density of 1 g/cm3 (SGU). Check for correct functioning in the event of other process medium conditions.
• The flow will not be significantly impeded if the tuning fork is correctly aligned and the marking is pointing in the direction of flow.
• The marking is visible when installed.

Screwing in the device

• Turn by the hex bolt only, 15 to 30 Nm (11 to 22 lbf ft)
• Do not turn at the housing!

Aligning the cable entry

The locking screw is not tightened when the device is delivered.

1. Loosen the external locking screw (maximum 1.5 turns).

2. Turn the housing, align the cable entry.
   Avoid moisture in the housing, provide a loop to allow moisture to drain off.

3. Tighten the external locking screw.

5.3 Sliding sleeves

For more details, see the “Supporting the device” section.

13.3.10 Electromagnetic compatibility

• Electromagnetic compatibility as per EN 61326 series and NAMUR recommendation EMC (NE21).
• The requirements of EN 61326-3-1 are fulfilled.

13.4 Process
13.4.1 Process temperature range
–40 to +150 °C (–40 to +302 °F)
Observe pressure and temperature dependency, see the “Process pressure range of the sensors” section.
13.4.2 Thermal shock
≤ 120 K/s
13.4.3 Process pressure range
WARNING
The maximum pressure for the device depends on the lowest-rated element, with regard to pressure, of the selected component. This means that it is necessary to pay attention to the process connection as well as the sensor.

• For pressure specifications, see the “Mechanical construction” section.
• Only operate the device within the specified limits!
• The Pressure Equipment Directive (2014/68/EU) uses the abbreviation “PS”. The abbreviation “PS” corresponds to the MWP (maximum working pressure) of the device.

Refer to the following standards for the permitted pressure values of the flanges at higher temperatures:

• PR EN 1092-1: With regard to its stability-temperature property, the material 1.4435 is identical to 1.4404, which is classed as 13E0 in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.
• ASME B 16.5
• JIS B 2220

In each case, the lowest value from the derating curves of the device and the selected flange applies. Canadian CRN approval: more details about the maximum pressure values are available in the download area of the product page under: www.endress.com→ Downloads.

Process pressure range of the sensors

PN: 40 bar (580 psi)
13.4.4 Test pressure
