2.9.1 Torques and pressures
Tightening of bolts
• Always tighten the bolts uniformly and in diagonally opposite sequence.
• Do not exceed the maximum torque value.
• Step 1: Apply approx. 50% of max. torque given in table.
• Step 2: Apply approx. 80% of max. torque given in table.
• Step 3: Apply 100% of max. torque given in table.
Maximum torque for 11864-2A flange version
CAUTION!
Please take care to use the proper gasket to prevent damaging the liner of the flowmeter. In
general, the use of spiral wound gaskets is not advised, as it could severely damage the liner of
the flowmeter.
Figure 2-21: Tightening of bolts
CAUTION!
The max. allowable torque depends on the gasket material, see datasheet for detailed
information. Bolts to be used from material SS, class 70-A2.

2.9.2 Installation of weld-on versions
For mounting sensors with weld-on connections, please follow the procedure as follows:
• Mount the sensor completely in the pipeline and spot the weld-on connections to the pipe. This
is necessary to align the mounting bores of the flange.
• Remove the sensor body and the gaskets from the adapters by loosen the screws.
• Weld the adapters completely to the pipe.
• When the pipe is cold again, reinstall the gasket and mount the sensor.

note of the voltage data on the nameplate!
DANGER!
Observe the national regulations for electrical installations!
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
DANGER!
The device must be grounded in accordance with regulations in order to protect personnel

3.3 Virtual reference for IFC 300 ( C, W and F version)
Benefits of virtual reference:
•Grounding rings or grounding electrodes can be omitted.
•Safety increases by reducing the number of potential leakage points.
•The installation of the flowmeters is much easier.
Minimum requirements:
•Size: tDN10 / 3/8"
•Electrical conductivity: t200 μS/cm
•Electrode cable: max. 50 m / 164 ft, type DS
