9 Installation example for a highly viscous liquid. Unit of measurement mm (in)
NOTICE
Highly viscous liquids may cause switching delays.
Make sure that the liquid can run off the tuning fork easily.
Deburr the socket surface.
High viscosity, e. g. viscous oils: < 10 000 mPa s
The tuning fork must be located outside the installation socket!

10 Installation examples for a highly viscous process medium
•Use short installation sockets to ensure that the turning fork can project freely into the vessel.
•Install preferably flush-mounted on vessels or in pipes.
•Leave sufficient distance between the buildup expected on the tank wall and the tuning fork.
5.1.4Take clearance into consideration
A0033236
Allow sufficient space outside the tank for mounting, connection and settings involving the electronic insert.

12 Support in the event of dynamic load
Support the device in the event of severe dynamic load. Maximum lateral loading capacity of the pipe extensions and sensors: 75 Nm (55 lbf ft).
5.1.6Weld-in adapter with leakage hole
316L
A0039230
Weld in the welding neck in such a way that the leakage hole is pointing downwards. This enables any leaks to be detected quickly.
•Open-ended wrench for sensor installation
•Screwdriver for electrical connection

A0039125 |
14 Marking to align the tuning fork
Use the marking to align the tuning fork in such a way that medium can run off easily and deposit buildup is avoided.
The following can be used as the marking:
•Material specification, thread description or circle on the hexagonal nut or on the weldin adapter
•The II symbol on the back of the flange or Tri-Clamp
Installing in pipes
A0034851 |
15 Marking and fork position |
•Flow velocity up to 5 m/s with viscosity 1 mm2/s (cSt) and density 1 g/cm3 (SGU) Check for correct functioning in the event of other process medium conditions
•The marking on the adapter points in the flow direction; the flow is thus not severely obstructed
•The marking can be identified while the device is installed
Screwing in the device
A0034852
16 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!

17 Housing with external locking screw
The locking screw is not tightened when the device is delivered.
1.Release the external locking screw.
2.Turn the housing, align the cable entry.
3.Tighten the external locking screw.
See the "Accessories" section.
5.4Post-installation check
Is the measuring device undamaged (visual inspection)?
Does the measuring device conform to the measuring point specifications?
For example:
•Process temperature
•Process pressure
•Ambient temperature range
•Measuring range
Are the measuring point number and labeling correct (visual inspection)?
Is the measuring device adequately protected against precipitation and direct sunlight?Is the device properly secured?

6Electrical connection
6.1.1Cover with securing screw
Covers with a securing screw are available for devices for use in hazardous areas. Do not release the screw fully.
A0039520
The protective earth conductor at the device must only be connected if the device's operating voltage is ≥ 35 VDC or ≥ 16 VACeff.
When the device is used in hazardous areas, it must always be included in the potential equalization of the system, irrespective of the operating voltage.
The plastic housing is available with or without an external protective earth connection (PE).
6.2.12-wire AC (electronic insert FEL61)
•Two-wire AC version
•Switches the load directly into the power supply circuit via an electronic switch; always connect in series with a load.
•Functional testing without level change
A functional test can be performed on the device using the test button on the electronic insert.
Supply voltage
U = 19 to 253 VAC
Residual voltage when switched through: maximum 12 V
Pay attention to the following as per IEC/EN61010-1: Provide a suitable circuit breaker for the device, and limit the current to 1 A, e. g. by installing a 1 A fuse (slowblow) in the line (not the neutral wire) of the supply circuit.
Power consumption
P ≤ 2 VA

Current consumption
Residual current when blocked: I ≤ 3.8 mA
The red LED flashes in the event of an overload or short-circuit. Check for an overload or short-circuit every 5 seconds. The test is deactivated after 60 seconds.
Power output and load current
•Max 89 VA/253 V (350 mA); max 8.4 VA/24 V (350 mA)
•Min 2.5 VA/253 V (10 mA); min ≥ 0.5 VA/24 V (20 mA)
•With overload and short-circuit protection.
Behavior of output signal
•OK status: load on (switched through)
•Demand mode: load off (blocked)
•Alarm: load off (blocked)
Terminal assignment
Always connect an external load. The electronic insert has integrated short-circuit protection.
