Unpacking and Inspection
Upon opening the shipping container, visually inspect the product and applicable accessories for any physical damage such
as scratches, loose or broken parts, or any other sign of damage that may have occurred during shipment
OTEE:
N
If damage is found, request an inspection by the carrier’s agent within 48 hours of delivery and file a claim with the
carrier A claim for equipment damage in transit is the sole responsibility of the purchaser
Mounting Locations
The transducers contain piezoelectric crystals for transmitting and receiving ultrasonic sound energy through the pipe wall
(DT9) and from the probe tip (DP7) Placement of the ultrasonic transducer is the most critical step in achieving an accurate
and reliable flow reading All flow meters of this type rely on a full-pipe of fluid that is flowing symmetrically (evenly) in
the pipe Flow in partially filled pipes and immediately downstream of elbows, valves and pumps is unstable and leads to
unstable readings and non-linearity
The DFX flow meter has software algorithms that assume a full pipe of liquid Install only in locations where the pipe is filled
at all times when flow measurements are required Avoid partially filled pipes that can lead to very large flow measurement
errors See
for possible pipe configurations
