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

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.

Repairing procedure

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.
