Figure 2-10. ControlWave EFM Direct Mount Installation with Cathodic Protection
Revised Dec-2013
You can mount the ControlWave EFM directly on the pipeline or
remotely on a vertical stand-alone two-inch pipe or on a wall. The Earth
ground cable must run between the EFM's ground lug and Earth ground
(rod or bed) even though the ControlWave EFM's multivariable
transducer (MVT) may be grounded to the pipeline. If any pressure
transmitters or pulse transducers are remotely mounted, connect their
chassis grounds to the pipeline or Earth ground.
For installation of the unit without cathodic protection, a direct
Note:
mount installation is similar to Figure 2-10 and a remote
installation is similar to Figure 2-11. The main difference is that
without cathodic protection, whether you're mounting directly
or remotely, you do not use the transducer to manifold dielectric
isolation kit.
You can mount the ControlWave EFM directly on the pipeline (using a
manifold block) or remotely on a vertical stand-alone two-inch pipe or
on a wall.
