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. Using the conditions specific to the measuring point, determine which installation
distances are necessary for installation.
2. Determine the values for the requisite installation distances.
A number of methods are available for determining the values:
– FieldCare (operating program) procedure explained in the Operating Instructions on
– Local operation of the device
– Applicator (software) procedure explained in the Operating Instructions on the
the CD-ROM
CD-ROM
– Premount the strapping bands (DN 50 to 200 / 2 to 8") or 
3. Mechanical preparation of the "Clamp On" holders for the sensors:
(DN 250 to 4000 / 10 to 160")
