measuring, counting and recording industrial waste

PORTABLE FLOWMETER DPN 7/4

• Self-cleaning Bubble to Bubble.

• Multicurve flowmeter and recorder with automatic editing of report analysis.

• Autonomy : up to 3 weeks.

• Robust : box made of reinforced polyester.

• 70 preprogrammed curves within flowmeter and downloading of other curves via a computer or a portable terminal.

• Facility for other associated measurements (pH, temperature, conductivity, dissolved oxygen, rain, etc...).

• Facility for data processing (Macintosh and PC).

• Facility for connection to one or two water samplers.

• A bubble gauge with built-in compressor and recorder DPN 7/4,
• A battery with charger (about 3 weeks autonomy),
• an optional graphic printer EGN 8/2,
• a rain gauge interface,
• 2 physical-chemical inputs (pH, temperature, conductivity, etc...).

The DPN 7/4 model included in the box measures the water level by injecting a very small air flow through a pressure pick-up (Bubble to Bubble system).

The flow is calculated according to the level and the type of contraction used.

The model DPN 7/4 is supplied with a built-in compact air generator.

On every single site, the user can choose from a variety of curves Q(h) including :

• Venturi, NEYRTEC and HYDROLOGIC flumes,
• NEYRTEC and HYDROLOGIC weirs,
• 2/1 and 1/2 streamlined triangular weirs,
• streamlined trapezoidal weirs,
• rectangular sharp-crested weirs,
• V-notch weirs (28.4, 45, 53.8, 60 and 90 degrees).

Any other curve may be downloaded by the user via a PSION terminal or an IBM computer.

Multiple site, data can be stored then transferred either in memory modules of an PSION terminal or in an IBM PC.

Data can be stored, analysed, and edited with our software OMNIDRO compatible, with the micro-computers IBM PC or Macintosh.

The portable flowmeter can be added to a portable waste water sampler (ranging from a single composite container to 24 individual containers).
