7-INSTALLATION
7.1
SAFETY MEASURE
Instructions and procedures in this section may require special precautions to ensure the safety of the personnel per
forming the operations. Information that raises potential safety issues is indicated by a warning symbol . Please refer
to the following safety messages before performing an operation preceded by this symbol.
7.2
WARNINGS
7.2.1 Explosions could result in death or serious injury
- Verify that the operating atmosphere of the sensor pipe and transmitter is consisten with the appropriate hazardous
locations certifications.
- Do not remove the transmitter cover in explosive atmospheres when the circuit is alive.
7.2.2 Failure to follow safe installation and servicing guidelines could result in death ors
eriousinjury
- Make sure only qualified personnel perform the installation.
- Do not perform any service other than those contained in this manual unless qualified.
7.2.3 High voltage that may be present on leads could cause electrical shock
- Avoid contact with leads and terminals.
7.3 PRE-INSTALLATION
There are several pre-installation steps that make the installation process easier. They include identifying the options
and configurations that apply to your application, setting the hardware switches if necessary, and consideration of
mechanical, electrical, and environmental requirements. Please remember that the sensor pipe liner is vulnerable to
handling damage. Never place anything through the sensor pipe for the purpose of lifting or gaining leverage. Damaged
liner can render the sensor pipe useless.
7.3.1 Identify Options and Configurations
Standard application of the RPmag includes control of the sensor pipe coils and one or more of the following con
figurations or options:
- 4÷20mA output
- Pulse output
- Alarm output
- Data logger
Be sure to identify the options and configurations that apply to your situation, and keep a list of them nearby during
the installation and configuration procedures.
7.3.2 Mechanical Considerations
The mounting site for the RPmag Integral Mount Transmitter should provide enough room for secure mounting,
easy access to the conduit ports, full opening of the transmitter covers, and easy readability of the local operator
interface (LOI) screen.The LOI can be rotated in 90° increments.
7.3.3 Lift
The flowmeter can be lifted using the lift as shown in following pictures. The safe load and measure for the lift
should reach to the relative requirement. Don’t lift the flowmeter using the rope to tie the connection between
the sensor and the transmitter (compact version) or the connecting box (remote version)

RPmag - installation
7.4
INSTALLATION GENERAL CRITERIA
The flowmeter can test automatically flow direction. Because the direction arrow marked on the nameplate is flow
direction when calibrated in factory, you should install the flowmeter to make the actual flow direction same as the flow
direction arrow marked on the nameplate. If this is not possible, simply reverse the direct flow direction through the
“Indication” (see par. 10.4.3.4.1)
The upstream straight pipe should be longer than 5XDN and the downstream straight pipe should be more than 3XDN
in order to guarantee the accuracy of measurement.
7.5 INSTALLATION IN PIPELINE
Installation may be horizontal or vertical, but make sure no deposit on the electrodes when horizontal installation.
See Fig.13-A.
Fig.13-A. Installation in horizontal or vertical pipeline
To install an rectifier or straight pipe is necessary to normalize the flow profile if there are pipe elbow, flow regulation
valve or half-open ball valve in front of the sensor. See fig.13-B.

The electromagnetic flowmeter can not be installed at the pipe highest point, because air or gas accumulations may
occur in the measuring pipe. See Fig.15-A
Fig.15-A Installation at highest point
The electromagnetic flowmeter can not be installed upstream of a pump to prevent cavitation, which can damage the
sensor lining. See Fig.15-B
Fig.15-B Pump proximity installation
Install a siphon (a) with a vent valve (b) downstream of the sensor in down pipes longer than 5 meters. This precaution
is to avoid low pressure and the consequent risk of damage to the lining of the measuring tube. See Fig.15-C
WARNING: all the phenomena that generate a strong depression inside the pipe can irremediably damage the insulating
coating of the sensor tube itself.

INSTALLATION PRECAUTIONS
An all-weather cover should be used to prevent the housing from the direct sunlight or rain when the device in outdoors
The flowmeter should the excessive vibrations, large ambient temperature changing and long-time shower. It should
be prevent from the leakage of the corrosive liquid.
7.7
PIPE CONNECTION
The sensor should be supported by the connecting pipes, it cannot withstand its own weight.
Mechanical and thermal stress must be avoided.

RPmag - installation
7.8
MOUNTING REQUIREMENTS
a) The sensor pipe and the line pipes must have the same axis. For the sensors under DN50, the axial difference
between the measuring tube and operating pipe should be less than 1.5mm; for the sensors from DN65 to DN300,
it should be less than 2mm; for the sensor over DN350, it should be less than 4mm.
b) The gasket between flanges should have a good corrosive resistance. The gasket must not extend to the pipe
inside.
c) The threads of the fasten bolts and nuts should be in good condition. The bolts should be fastened using torque
spanner with certain torque according the size of flange.
d) It should take separate measure to prevent the lining from heat when weld or flame cutting in the pipe closed to
sensor. If the sensor is installed in a well or immersed in water, the connecting box for sensor must be filled
and sealed with sealing glue after commissioning.
7.9
ACCESSORIES
7.9.1 Grounding ring optional
Material: SS 316L or Hastelloy C
Thickness: 3mm for SS 316L or 1mm for Hastelloy C
For the non-conductive pipe, the grounding rings should be installed between the flanges of sensor and pipe to make
the flowmeter and measured medium at same potential.

7.10 EQUIPOTENTIALITY AND ELECTRICAL INTERFERENCE REDUCTION
The measuring circuit assumes the fluid at ground potential, as it is in most of application with conductive pipes.
The sensor is isolated from the fluid because of the lining, therefore it’s necessary to connect the grounding cables to
the pipe’s flanges, as shown in fig. 18-A. The resistance for grounding connection should be less than 10ohm.
Most of application do not require special precautions for installation, the only requirement is to keep the signal cable
separate from the main cable. In case of sensor with cathodic protection or electrolysis processes, the main current
shall not flow through the measured fluid..
The following measure should be taken in order to reduce the influence of magnetic field:
a) With conductive pipes, potential equalization is made by connecting sensor and the adjoining pipes as shown in
figure. The bolt connection for flanges can not be used instead of the electric connection, it must have an additional
electric connection as shown in Fig.18A.
Fig.18A Sensor equipotentiality
b) For the non-inductive pipe, the grounding rings should be installed between the both flanges for sensor and the
both flanges for pipe. See Fig.18B.

c) Some systems, such as pipes with cathodic protection, may be affected by potential disturbance because not all the
line is at ground potential. In order to eliminate this type of interference, it must be isolate the line with two rubber
pipes as shown in Fig.19A.

7.11 PREPARATION FOR OPERATION
Strictly check the instalment and wirings before it gets into operation!
It shall be pointed out that the instrument, including the sensor and converter has been fully adjusted, calibrated
with actual flow, and inspected under strict measures. All the units are certified. No further adjustments are
required when put it into operation. Observing the contents in this manual, to check and analyze any malfunction
The following steps are to be followed to get the instrument into operation.
1) Make sure that the sensor is completely filled with fluid.
2) Turn the power supply ON. After approx. one minute, the display will show a value which indicates that the
wire connection is correct. If the fl ow value is negative, it can be adjusted
3) Zero verification. Shut off the valve tight in downstream first and then the valve in upstream,
to let the liquid stops to flow in the pipeline. The displayed value should be 0. The value displayed can be
corrected at the converter if the value is different than 0.
7.12 MAINTENANCE
Generally, no extraordinary maintenance is needed on magnetic flowmeter.
Only in case the product can adhere to the inner wall of the sensor, and its electrodes, it is necessary to perform
periodic cleaning operations.
Be careful not to damage the lining and the electrodes.

RPmag - electrical connections - digital output
8.5.2 Digital output
When digital output is set in frequency mode, it generates an 0.1÷10000Hz output signal proportional to the measured
flow rate; however if it’s set in pulsed mode generates an output signal in relation to the totalized volume increase.
The signal is normally used in combination with an external totalizer, a pulse counter or an acquisition system.
The resistance in the circuit must be equal to or greater than 100Kohms.
Follow the below steps to connect the signal cable to the transmitter:
1) Insert signal cable through the cable gland.
2) Connect two wires to F/P+ and F/P- terminals
N.B. - When the RPmag pulse output is connected to an acquisition system that requires a current higher than
11mA, a properly sized pull-up resistor must be connected to ensure the minimum current required by the acquisition system connected (see drawing below); example: if the acquisition system requires a min. current of 15mA,
a 1,6 Kohm pull-up resistor must be connected (according to the calculation R = V / I = 24V / 15mA = 1,6Kohm)
between an external power supply of 24 Vdc and the acquisition system input terminal

8.6.3 D.I. digital input
The “D.I.” optically isolated digital input can be driven by a normally open contact, with a
minimum voltage of 10Vdc up to a maximum of 26Vdc.
Closing the contact as “DI” terminals, the batch counter will be reset and the RL1 output
will again be energized with closed contact.
N.B. - The batch counter can be reset only when its value is equal or greater than the
threshold set (see “BATCH” parameter).
Activing the partial totalizer function (PARTIAL TOT), it is possible, closing the contact, in order: start,
stop and reset the counting.

REMOTE VERSION
During the remote version installation comply with the following information to ensure correct measurements:
1) The cables must be as short as possible, especially with low conductivity fluids.
2) The cables should be far from electrical machinery and switching devices such as contactors or solenoid valves.
3) The cables must not be in conduit with power cables or cables for the switching devices control.
4) When necessary, ensure the equipotential between sensor and transmitter.
5) The maximum cable length is a fluid conductivity function. Refer to paragraph 8.7.2.

RPmag - troubleshooting
In some circumstances, process conditions themselves can cause the meter output to be unstable. The basic
procedure for addressing a noisy process situation is outlined below. Complete them in order. When the output attains
the desired stability, no further steps are required:
1.
2.
Increase the Damping
Check the Ground connection
If the basic steps for troubleshooting are not sufficient contact our technical support.
