CorrTran MV Corrosion Monitor

3.3 Mounting safety procedures and hints
The CorrTran MV must be installed in locations that are most susceptible to corrosion.
In most cases, the highest levels of corrosion tend to occur where water is trapped or
stagnant.
The electrodes selected must reflect the same metal properties as the piping or other
components susceptible to corrosion. For example, in applications where the pipe is made
of stainless steel and the water pump’s impeller is made of carbon steel, the impeller will
corrode faster than the pipe. In this case, it is advisable to select electrodes that are made
of the same material as the pump’s impeller.
3.3.1 Mounting requirements / scenarios
The transmitter should not be mounted in a pipe drop since the corrosive liquid
may not be in full contact with the electrodes as shown in Figure 8.
CorrTran MV should be mounted in the riser of a pipe near an elbow where the
velocity is the highest. In general, CorrTran MV should be mounted in pipes
or tanks at locations of highest liquid velocity and constant immersion, shown
in Figure 9. For velocities greater than 20 fps, the protruding finger electrodes
must be protected. As noted above, high fluid velocities can also cause unwanted
turbulence in the pipe due to the extension of the probe. Using an adjustable CorrTran MV
probe with electrodes mounted flush to the wall of the pipe will eliminate this problem.
