Preparatory steps prior to installation
Depending on the conditions specific to the measuring point (e.g. clamp-on, number of traverses,
fluid, etc.), a number of preparatory steps have to be taken before actually installing the sensors:
1.
Determination of the values for the necessary installation distances based on the conditions
specific to the measuring point. A number of methods are available for determining the values:
– Local operation of the device
– FieldCare (operating program), connect a notebook to the transmitter
– Applicator (software), online on the Endress+Hauser Internet site
2.
Mechanical preparation of the clamp-on retainers for the sensors:
– Premount the strapping bands (DN 50 to 200 / 2 to 8") or (DN 250 to 4000 / 10 to 160")
– Fix the welded bolts
3.4
Determining the necessary installation distances
The installation distance that have to be maintained depend on:
• The type of sensor: W (DN 50 to 4000 / 2 to 160"), W(DN 15 to 65 / ½ to 2½")
• Type of mounting:
– Clamp-on with strapping band or welded bolt
– Insertion version, installation in the pipe
• Number of traverses or single-path/dual-path version

Determining values for installation distances
Perform the following steps to determine the installation distances:
1.
Mount the transmitter.
2.
Connect the power supply.
3.
Switch on the measuring device.
4.
Run the "Sensor Setup menu.
