1.1 Designated use
The CorrTran MV is a compact, 4-20 mA corrosion transmitter used to detect general
corrosion, localized corrosion, and conductance in a wide range of industries. The
transmitter measures the corrosion rate and pitting factor, giving the readout in mil/year or
a 0-1 pitting factor, respectively. It also provides a conductance measurement. The readings
are taken in real time and are updated every 21 minutes.
1.2 Installation, commissioning, and operation
CorrTran MV is designed to operate safely in accordance with relevant technical and
safety standards. If installed incorrectly or used for applications for which it is not intended,
application-related dangers may arise. For this reason, the instrument must be installed,
connected, operated, and maintained according to the instructions in this manual by
appropriately trained personnel. This manual must be read, understood, and the instructions
must be followed. Modications and repairs to the device are permissible only when they
are expressly approved in this manual.
1.3 Operational safety
Measurement systems used in a hazardous (classied) area must comply with all existing
national standards. CorrTran MV can be supplied with the certicates listed in Table 1. All

CMP retractable ange probe
The CMP retractable ange probe (Figure 6) is an adjustable-
length probe. A specially designed packing gland is used with
the probe for insertion into or retraction from a pressurized
system without a process shutdown. The packing gland
is welded to a 1” pipe nipple with bleed valve attached to
a specied ange, and is designed to mount easily on a
matching ange valve. The probe assembly consists of a
packing gland, 1” pipe nipple with bleed valve welded to
specied ange, an insertion rod with a hermetically sealed
three-electrode end cap, and a six-pin connector welded in
place. A safety chain is also provided to prevent blowout. The
insertion length (I. L.) is calculated to the end of the electrode
and can be specied by the customer. This probe is only
available with the remote mounting option.
Electrodes shown in the picture are ordered separately.

Retrievable Probe
and Probe Adapter
CMP retrievable probe
The CMP retrievable probe (Figure 7) is a xed-length probe. It is
designed to be used with HPTM and MHTM high-pressure access
systems. The probe assembly consists of an insertion rod with a
hermetically sealed three-electrode end cap, a hollow plug nut, and a
standard six-pin connector, which are all welded in place. The hollow plug
nut on the probe screws into the hollow plug of the access system. This
allows the probe to be installed in the process, using a retrieval tool and
service valve, without process shutdown. The insertion length (I. L.) is
calculated using one of the formulas bellow and must be specied by the
customer. This probe is only available with the remote mounting option.

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 reect 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 nger electrodes
must be protected. As noted above, high uid 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 ush to the wall of the pipe will eliminate this problem.

CorrTran MV can be located at any point on the pipeline but should always be immersed in
the corrosive material as shown in Figure 10.

A tee in the condensate return line (Figure 11) is a good location to mount CorrTran MV.

CorrTran MV should be located downstream of a control valve for best performance and
can also be located in the deadleg portion of a by-pass. Note that the transmitter located
in the by-pass leg should be mounted in front of the valve for best performance. As shown
in Figure 12. This guarantees that the electrodes will always be immersed in the corrosive
material.
Figure 12. CorrTran MV Located in Bypass Loop
Installing separate CorrTran MV units with different electrode materials on the
suction side of the pump will ensure monitoring of the pump impeller and the pipe
as shown in Figure 13.
There should be a minimum separation distance of 50 cm (19.7”) between probes.

In addition to pipes, a condensate ash tank, shown in Figure 14, is also a good application.

It is essential that isolators are installed between the transmitter and the control
system if the I/O card is not fully isolated from the ground. See section 4.3 for
more information on the proper installation wiring.

3.4 Installation instructions
3.4.1 General
A trained specialist must perform the necessary installation and commissioning
of CorrTran MV. Recognized rules of the technology and setup requirements
must be maintained both during and after installation. Safety requirements
must be observed during all installation steps.
If the pipe or vessel into which the CorrTran MV is to be inserted is under
pressure and/or contains any hazardous substance, such as steam, caustic
solutions, acids, toxins or other substances specied by OSHA as physical or
health hazards, the pipe or vessel must rst be depressurized, any hazardous
substance purged therefrom, and appropriate lockout/tagout procedures
observed in accordance with Section 1910.147 of the OSHA Regulations,
before CorrTran MV can be installed. Failure to follow these procedures may
result in serious injury or death.
CorrTran MV consists of three basic components:
Transmitter: A transmitter housing contains the electronics and provides the 4-20 mA with
HART output signal.
Probe: There are two basic options, direct mount and remote mount. The remote mount
probe is supplied with a 6’ or 12’ cable.
Electrodes: Either nger electrodes or electrodes ush to the probe end are used. Correctly
chosen electrodes will corrode in the same manner as the metal being investigated. For
accurate measurements, the electrodes must reect the same metal properties as the
metal being investigated.
3.4.2 Electrode installation
The electrodes are shipped loose and must be installed hand-tight. Ensure that the Viton
(standard) or Kalrez (on request) gaskets are in place prior to installing the electrodes. See
Figure 17 for the electrode installation drawing.
Metal Samples recommends changing the electrodes when they are at 50% of
their useful life:
