Flowmeter OREO for DN100 mm - Pressure 0.1-25 bar - Flow 1.2 – 300 m3/h

® OREO (flowmeter)
Main features


This flowmeter is a mechanical inspection device to check flow and volume for fire hydrants.

The mechanical flowmeters DB100A and DB100AL comply with the requirements of the users in terms of metric flow reliability; they are handy and easy. The DB100 displays the volumes and the flows for use from 1 to more than 300 m3/h with a precision of reading of 0.1 m3 for all measures. The use of batteries EF with very high longevity enables a permanent and autonomous operation during 10 year.

Measure - flow measurement from 1.2 to 300m3/h

To meet all your needs, the DB100 display the volume and flow from 1.2 to more than 300m3/h with an accuracy of 0.1 m3. Manometer precision 0.05 bar.

The new manometers color offers a static and dynamic reading very precise of the pressure from 0.1 to 25 bars.

Handiness – Easy checking

The foam handle and the conception in one piece stainless steel EF enable a very good catch in hand without tiredness.

Featherweight: 6.5 kg for the DB100A. The DB100A is at the moment the lightest flowmeter on the market thanks to the choice of materials of low density

Protection – Reinforced fittings: 25 bars

The high resistant fittings 25 bars, and the epoxy coating, ensure longevity in difficult working conditions.

Tight electronics: IP68 STAINLESS

To secure the electronic display of any water projection, all the DB100 are equipped with flexible tight protection.


Energy: minimize the external consumption of energy from the longevity of the batteries with low level of discharge + limit rejection batteries.

Materials: used in durability, that limits the consumption of raw materials.

Recycling: 90% of the DB100 are easily recycled (possible reprocessing by EF-OREO).

Repairing procedure

IndicationsCorrective actionRepair


Repair on site.

Scratched paint

To retouch with paint containing polyurethane (colour RAL 3000).

Damaged foam of the handle

To remove the handle support using a screwdriver and to change the foam of protection.

Damaged label

To unstick carefully the label with the cutter, to clean the residues of adhesive and to stick new labels.

Electronic display

Do not indicate any more the flow

To open the lid by unscrewing the 4 higher screws, to change the battery then to screw again the lid with its screws.

Do not indicate any value

To open the lid by unscrewing the 4 higher screws, to change the batteries.

Became wet

To open the lid by unscrewing the 4 higher screws, to remove the batteries and to let dry 72 hours minimum. To place the batteries, to change the tightness seal and to screw again the lid.

Unstable display after change of the turbine

To tighten the stainless nut which maintains the turbine on its axis of 1/8 turn

Mechanical pieces

Damaged manometer

To remove the old one and to replace it

Damaged electronic parts

To remove the lid, to disconnect the four electric wires, then connect them on the new electronics, and screw again the lid.

Damaged turbine

To remove the old one by withdrawing the stainless nut of the axis and to replace it.

Difficult or impossible rotation / difficult reading of the flow

To check that there are no foreign parts which block the turbine, if not to replace the PFTE washers by the similar ones.

Structure parts

Damaged body or damaged valve

No corrective action.

Control and calibration


Each device is checked in the factory.

At the end a report is written and attached to each device.


Each device is calibrated in a laboratory approved DRIRE under the number N° 80 380 2 05 01.

This laboratory has standards connected COFRAC. This laboratory can check any device of different marks.

At the end of the control a certificate is established and joined to each device.

Use (DB100)

- Before each test it’s always necessary to carry out a purge of the installation, without the flowmeter

- Don’t close the valve downstream too quickly in order to avoid the “water hammer” effects which could involve the deterioration of the flowmeter.

Before any checking

- to make safe the surface of checking and to materialize it,

- to check that the gate valve is opened with its maximum,

- to carry out a purge of the pipeline in order to prevent that any foreign elements, like stones for example, do not deteriorate the flowmeter DB100

Static pressure

- to install the DB100 respecting the right direction of assembly

- to install the valve downstream (if not integrated)

- to install the discharge pipe

- to open partially the valve downstream of the flowmeter DB100

- to open the valve of the fire hydrant (don’t exceed 100 m3/h)

- to close the valve downstream of the flowmeter

- to measure the value displayed on the manometer

Flow under 1 bar

- to open to the maximum the valve of the fire hydrant (13 turns)

- to regulate, by opening the valve downstream of the flowmeter, pressure at 1 bar (*)

- to record the value displayed in m3/h (letter R on the monitor)

- to close again, slowly, the valve of the fire hydrant

- to remove the flowmeter

(*) If the displayed flow becomes too important before to have obtained the pressure of 1 bar, measure the displayed pressure at 60m3/h to define the conformity of the fire hydrant.

Choice between FLOW and CUMULATED VOLUME

Through successive support, we obtain by alternation:

- If Flow (in m3/h): presence of the letter R before the display

- If volume (in m3): no letter before the display

R – not used

Operation limit

To take care of the measuring device avoiding all shocks and remains < 300 m3/h and 16 bars. IP68 resists to water projections without pressure, but the bill-poster cannot be drowned.

To refer to technical documentation to know the operational limits.
