Drill a 48.5 mm diameter hole in the pipe to insert the fitting and weld the fitting to the
pipe.
The axis of the insertion fitting should be perfectly perpendicular to the pipe axis.
If the pipe is made of concrete or other material to which the insertion fitting cannot be
welded, a collar fitting or saddle fitting should be used. In this case, please contact us to
inform about the suitable sensor length.

MOUNTING THE SENSOR
Once the insertion fitting is mounted, place the flat seal in its position and install the
sensor with the arrow pointing in the flow direction. The electrodes must be perfectly
perpendicular to the pipe axis.
In order to align the sensor, the two bolts or pins situated in each side of the cylinder in
the top of the Flomat sensor must be aligned with the axis of the pipe and the arrow
pointing in the flow direction.
5.1
Tightening torque
The tightening torque for the flange screws should not exceed 7.1 Nm.
The tightening torque for the threaded fitting should not exceed 21 Nm.
5.2
Electronic converter connection
The top of the sensor is cylindrical and it can be adapted to a connector with cable for
remote electronics or to other types of electronic housings directly on the head.
In the event that during the installation of the sensor the electronics or the sensor cable
were disconnected, simply replace the two connectors on the sensor, push the mesh
above the head, tight the side screws, and in the case of separate electronics, tigth the
cable gland in order to keep the seal.
In the cases where the electronic converter is separate, refer to the converter instructions
manual for the cable connection.

CONFIGURATION
For the commissioning, in most of cases it is necessary to configure the equipment to put
the installation into service.
6.1
Fc factor
The Flomat sensor has been calibrated in our calibration rigs to determine the "Fc" factor.
This factor corresponds to the signal level with a certain liquid velocity in the pipe.
If the sensor is supplied with an electronic converter, this factor will already be
programmed into the converter, but if not, the electronic converter must be programmed
by entering this factor (Fc).
6.2
Pipe diameter
It is very important to verify that the converter is configured for the diameter of installation
pipe.
For XT5 converter series, the inner diameter (DN) is programmed directly in mm. For the
MX converter series of converters, the inner diameter is programmed by means of the
nominal flow rate equivalent to a velocity of 5 m / s (Qnom.). Qnom values depend only on
the inner diameter of the pipe and they are shown in the table on page 8 for most
standard sizes.
