Woltex M

Horizontal Woltmann meter with extended accuracy range for water distribution applications

Woltex M is a horizontal Woltmann meter available in sizes from DN 50 to 500. With its extended accuracy range it is dedicated to all applications around water distribution where high reliability and accuracy is requested.

FEATURES AND BENEFITS

  • Hermetically sealed register (copper can/mineral glass envelope)
  • Extended range approval
  • Interchangeable approved mechanisms without re-calibration
  • Pre-equipped through Cyble as a standard
Endurance & Peak Flow Resistance          Communication Device
This extended approval is the result of          Pre-equipped for future communication
more than twenty years experience in           through Cyble.
Horizontal Woltmann design, from the
fi rst hydrodynamically balanced helix
patent in 1985 still resulting in unmatched
endurance capabilities to the use of high
quality materials.

Extended Approved Range

Variable Qn EEC/ISO approval of Woltex M ensures an unmatched approved range of 107:1 (from Qmin to Qmax) instead of 66:1 for standard class B meters. This is ensuring accurate and reliable data collection in a large scope of fl ow-rates typical of water network applications. Leakage detection as far as peak demands are accurately monitored initially and over time.

Ease of Installation, Read and Maintenance

Woltex M range is available in various lengths and connections to minimize installation costs. Interchangeable approved mechanisms allows easy maintenance without re-calibration. Ease of read in the toughest environments (ie: fl ooded pits) is secured by orientable hermetically sealed register (copper can/ mineral glass envelope).

Deskripsi

WORKING PRINCIPLE

The water velocity is rotating the horizontal axis propeller. Special shape of its inlet and outlet bearing 1 is counteracting the natural hydraulic thrust applied on the propeller then preventing any downstream pivot wear.This hydrodynamic balance was fi rstly patented on Woltex range in 1985 and still features Woltex with unmatched enduring capacities. This results in a meter able to withstand sustained high fl ows without impacting low fl ow accuracy. This allows Woltex to be approved according the provisions of EEC/ISO with variable Qn extended range. The propeller rotation is transmitted by  a protected transmission and direct magnetic coupling 2 to the register. The cast iron body 3 is durably protected against the effects of corrosion by epoxy powder coating. The hermetically sealed copper can/mineral glass register 4 is safeguarding the read and integrity of the indicator in the toughest environments. (fl ooded pits, mechanical tampering attempts, …).

COMMUNICATION

Woltex M is supplied pre-equipped withCyble Target Allows communication and remote reading through:

  • Pulse output (Cyble Sensor)
  • M-Bus protocol (Cyble M-Bus)
  • Radio frequency wireless link (Cyble RF)

Compatible with Itron complete offer for Metering Point Management (Automated Remote Reading, Metering Point Analyser, Automated Meter Data Collection):

  • AnyQuest
  • EverBlu
  • WaterMind

These Cyble modules allow the Woltex M meter to be connected with various associated systems if and when desired. They are particularly adapted to commercial and industrial applications where a need for frequent meter monitoring is expressed especially in hard-to-read locations.

INSTALLATION REQUIREMENTS

» Woltex M could be installed regardless of position (EEC/ISO approval class B all positions).

  • Installation of a strainer upstream of the meter is recommended to protect the hydraulics against raw particles (see Itron strainer leafl et).
  • We recommend the installation of a fl ow straightener directly upstream of the meter to
    cancel the effects of hydraulic perturbations on Horizontal Woltmann accuracy (see Itron straightener leafl et).
