10. Appendix2-W210 Insertion Transducer
10.1 Overview
W210 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 installed is DN2000. Fluid temperature range: +10
℃
~+80oC. Sensor cable
length (9m standard) normally can be extended to as long as 100m.
Figure 1 shows a diagram of the W210 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-ring seal and joint nut guarantee user
safety while installing or operating the transducer.

10.2 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 related section in the manual.
10.3 Determining Transducer Spacing & Transducer Installation
The mounting space of insertion transducer is the center-to-center hole distance between the two transducers
(please refer to Menu 25). After enter the right parameter, please check the mounting space in Menu 25. (unit:
mm)
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 then weld it on the pipe
vertically.(When the flowmeter need to be hot-tapped into the pipe under pressure without flow
interruption ,please refer to the Sitelab operation construction of DDK electric Hot-tapping or corresponding
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
