Description

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.

Environment

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).

Maintenance

The DB100 don’t need any particular maintenance. A cleaning from time to time and a respect of the water material are sufficient to keep the flowmeter in good conditions of operation.

Repair: 90% of all the problems can be solved by the user through these instructions.

Assistance: If necessary, please contact our technical department.

Control and calibration

Control

Each device is checked in the factory.

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

Calibration

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.
