WORKING PRINCIPLE
helical rotor turns freely inside a cylindrical tube.
One
The working liquid pushes the rotor blades, making them turn at a flow speed which is
proportional to the flow rate.
A pick-up coil mounted externally receives the propeller turns and generates an electrical
signal which, once treated by the different electronic converters, can provide flow rate
indication, total or partial volume, digital and analog outputs.
2 RECEPTION
The TM turbine flowmeters are supplied individually packed for protection during transport
and storage including their corresponding instructions manual, for their installation and use.
All the flowmeters have been verified in our flow rigs, obtaining the K factor for each device.
2.1 Unpacking
Unpack the instrument carefully, removing any remains of the packing from the inside of
the sensor.
2.2 Storage temperature
-20ºC ... +60ºC
3 INSTALLATION
The installation must be made in a point that ensures that the pipe is completely full of
liquid.
Highest points in the installation as well as downwards pipes must be avoided, since air
pockets or vacuums might occur.
In installations where air can be present, a degasser must be installed before the
flowmeter.
Partially full pipe can involve important measurement errors.
4
Page 5
3.1 Filter
A filter should be installed before the turbine to guarantee correct working and avoid
expensive damage. The filter should have a mesh size of maximum of 200 µm to avoid
larger particles that may block the turbine propeller .
3.2 Open discharge
When the flow measurement is to be made before an open discharge, it is necessary to
install the flowmeter in a section of pipe with a trap which avoids the presence of air inside
the meter.
3.3 Position
The installation and position of the turbine flowmeter can be either vertical, horizontal or
inclined. Make sure that the flow direction is as marked by the arrow on the turbine body.
3.4 Straight pipe sections
To obtain good readings, turbulences must be avoided. For this it is necessary to have
straight sections of pipe upstream and downstream of the turbine. The straight pipe
sections must be of the same internal diameter as the turbine and the minimum lengths
must be the following:
Upstream 10 DN
Downstream 7 DN
These sections must be free of deviations or disturbing elements (valves etc.).
5
Page 6
These distances can be reduced by installing a flow straightener upstream of the turbine
at a distance equivalent to 5 DN.
3.5 Valves
Regulating or shut-off valves must always be installed after the turbine, in order to assure
that pipe is full of liquid.
3.6 Pumps
Pumps must always be installed before the turbine in order to avoid cavitation.
This way the presence of air pockets in the flowmeter is avoided, which could cause
unbalance of the propeller which could damage the turbine.
Note: To avoid cavitation the pressure at the outlet of the turbine should be higher than
twice the pressure loss of the turbine (see table Nº 2) plus 1.25 times the vapour pressure
of the liquid or its most volatile component.

Page 7
3.7 Electrical connection
It is important to keep the connecting cable between the flowmeter and the auxiliary
electronics away from mains or power supply cables, in order to avoid interferences. In
any case, those should be separated at least 5 cm.
The turbine flowmeter has an IP65 connector fastened to the counter by means of 4
screws. The connector consists of 3 parts joined by threaded nuts. (See figure).
Loosening the larger nut in the middle of the connector allows us to withdraw the half
where the cable will be later soldered.
The other half of the connector is fixed to the counter and should not be removed, except
when servicing the detector (See point 4.5 of the MAINTENANCE section).
The removable part of the connector consists of the cable gland at the top and the
electrical connection protector housing.
Before starting the installation, check that the cable gland is the right size for the cable to
be used. This will guarantee the instrument will stay watertight. The cable gland used is
for cables with outside diameters between 6 mm and 10 mm.
The electrical connection protector housing is dismounted by loosening the second nut.
When this is removed, the three connector terminals are visible.
7
Page 8
The terminals are numbered 1 to 3 and the connection is as follows:
Nº 1: Ground
Nº 2: Coil
Nº 3: Coil
Before soldering the connections, unscrew the cable gland and feed it, together with the
electrical connection protector housing, over the cable.
The joint between the cable and the connector should always be soldered, and should be
tidy and without short circuits between terminals.
Peel the outside insulation to free the inner cables. It is recommended to tin the ends of
the wires to avoid loose ends.
Once the connections have been made, the housing should be mounted screwing it on
and then the cable gland should be tightened to avoid entry of any liquid or humidity.
Once assembled the half of the connector, the mounting in the base has only one position
defined by the keyway between the two parts.
Check that the rubber seal is in its position inside the connector base. If this is the case,
introduce the connector half in the base, positioning by the keyway, and screw on the nut
until the end of the thread is reached.
4 MAINTENANCE
The simple construction of the TM turbine results in a long life in normal working
conditions.
The life of the parts depends mainly on the abrasive characteristics of the product to be
measured and the maximum flow rate.
The combination of these two factors make it difficult to estimate the life of the
components in good working conditions.
If the maximum flow rates given for each DN in the following table are exceeded the life is
considerably reduced.

The only parts that may need periodical maintenance are the propeller shaft and bearing.
The rest of the pieces will only need maintenance when there is chemical attack or
abrasion by the fluid being measured.
It has been confirmed that the life of these parts under normal working conditions is longer
than 20.000 hours.
4.1 Disassembly
The numbering of the different elements corresponds to the table and drawing in the
“Parts List” section on Page 10.
Inside the metering tube (1) are located the deflectors (2) (9) and the propeller (6). The
inlet deflector (2) has a stop (4) inserted and the outlet deflector (9) has a shaft (8).
The deflectors are dismounted by withdrawing the circlips (3) which hold them in. They
are mounted at about 5 mm from the ends of the metering tube and are easily removed
with a screwdriver.
Remove the circlip of the outlet deflector. Place the turbine in a horizontal position and
withdraw the deflector. The propeller assembly will come out together with the deflector.
Remove the circlip at the other end and withdraw the inlet deflector.
4.2 Cleaning
The propeller assembly contains the bearing (7) and the tungsten disk (5). These must
not be disassembled.
To clean the inside of the bearing use a cloth or soft paper wrapped around a fine shaft;
do not use abrasive elements. Cleaning liquids can be used to help remove dirt or grease.
To clean the propeller shaft (6) clean with a cloth soaked in alcohol, soapy water or
solvent. The propeller should rotate freely on the shaft but should not be loose. It should
not have a play of more than 1 part in 50 of the shaft diameter.
The rest of the pieces can be cleaned with the same products.
4.3 Mounting
Before starting to mount the turbine make sure that all the pieces are completely dry, with
this we can prevent the propeller shaft from seizing.
The turbine should be mounted as follows:
Slide the inlet deflector (2) in its place (use the flow direction arrow to determine the
correct end) and fix it with a circlip (3).
Fit the propeller assembly on the shaft (8) of the outlet deflector (9).
With the metering tube (1) in a horizontal plane introduce the outlet deflector assembly
and fix it with a circlip (3).
Check that the assembly is not loosen and that the two circlips are correctly seated. There
should only be about 0,5 mm axial play of the propeller assembly on its shaft.
The turbine is ready for installation and operation.
4.4 Pickup
To determine if the pickup group is working properly, the impedance between terminals 2
and 3 of the base connector (14) have to be measured with a multimeter. The value
should be between 1500 and 2500 Ohm.
4.5 Replacing the pickup
The female plug (13), as indicated in the Installation section, can be removed from the
base (14) by unscrewing the larger nut. The male connector base is fixed to the coil
support (11).
Unscrew the female connector in order to separate the cable and after that unscrew the
pickup group from the turbine metering tube (1).
To insert a new pickup group, follow the inverse process.
