Tecfluid MX4 For FLOMAT Series - Manual (Page 14)

Example:
Suppose a pipe of 300 mm inner diameter (DN300) and 5.5 mm thick. In the chart we can
see that the distance that the insert pipe adaptor must extend above the external wall is H
= 60,5 - s = 60,5 -5,5 = 55 mm.
The values in the chart are calculated considering the gasket supplied with the instrument,
which is 3 mm thick. If the thickness of the gasket is changed, the value of H will change.
The equation to calculate H’ for a gasket of thickness d is the following:
H’ = H + 3 - d
In the previous example, if the gasket was 5 mm thick, the distance that the adaptor
should extend above the external wall would be H’ = 55 + 3 - 5 = 53 mm.
Drill a 48.5 mm diameter hole in the pipe to insert the adaptor and weld the fitting to the
pipe.
If the pipe is made of concrete or other material to which the insert pipe adaptor cannot be
welded, a a clamp-on accessory or saddle should be used. In this case, please contact us
to inform about the suitable sensor length.
The axis of the insert pipe adaptor should be perfectly perpendicular to the pipe axis.
5.2 Sensor mounting
Once the insert pipe adaptor 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.
5.3 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.
5.4 Electronic converter connection
See point 2.1 MX4 converter on page 15.
5.5 Electronic converter programming
FLOMAT sensor is insertion type, so it can be installed in pipes with different diameters.
NOTE: It is essential to program the internal diameter of the pipe, in order that the
converter can indicate the correct flow rate.
Programming of the pipe diameter is explained in point 6.4 MX4 converter on page 30 of
this manual.
6 MAINTENANCE
It is recommended to clean the electrodes in installations where appreciable incrustations
or sedimentations can occur.
Cleaning can be done using liquid detergents and medium hard brushes.
