Inlet and outlet runs
If possible, install the sensor well clear of fittings such as valves, T-pieces, elbows, etc. If several
flow obstructions are installed, the longest inlet or outlet run must be considered. Compliance
with the following inlet and outlet runs is recommended in order to ensure measuring accuracy.

2.2 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 measu
ring 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:
– Local operation of the device
– FieldCare (operating program) procedure explained in the Operating Instructions on
t
he CD-ROM
– Applicator (software) procedure explained in the Operating Instructions on the
CD-ROM
3. Mechanical preparation of the "Clamp On" holders for the sensors:
– Premount the strapping bands (DN 50 to 200 / 2 to 8") or
(DN 250 to 4000 / 10 to 160")
