10.1 Overview
W211
type insertion transducers can be installed into metal pipelines via an isolation ball valve (installation into
pipelines of plastic or other materials may require an optional mounting seat). The maximum pipe diameter in
which insertion transducers can be
length (9m standard) normally can be extended to as long as 100m.
Figure 1 shows a diagram of the W211
Insertion Transducer. The insertion transducer is attached to its mounting
base
(which is welded to the pipe section at the measurement point) via a ball valve. When the transducer is
removed, pipe fluids can be contained by shutting off the ball valve. Therefore, installation and extraction of the
transducer can be performed without
relieving pipeline pressure. An O

Measurement Point Selection
To guarantee highly accurate measurement results, it is necessary to select an appropriate measurement point
before installing the transducer. For examples of measuring point selection, see the relat

Mounting method:
1.
Drilling at the measuring point, the diameter of the drilling hole is 24mm. Before drilling, please make the
hole center of transducer mounting base aim at the drilling hole center, and
vertically.
(When the flowmeter need to be hot
interruption,please refer to the Sitelab’
equipment.)
2. Close the ball
valve and screw it tightly on the mounting base.
3.
Twist off the locknut and loose the lock ring, pull the transducer into the joint nut, and then screw up the
joint nut on the ball valve.
