1.1 Designated use
The measuring system Promag 51 is PTB certified for custody transfer with cold water and may be
used for measuring the flow of freshwater having a minimum conductivity of 5
µ
S/cm. A minimum
conductivity of 20
µ
S/cm is required for measuring demineralized water.
The Promag 51 is operated with a totalizer display suitable for custody transfer and, optionally, with
a pulse output suitable for custody transfer. The measuring system operates within a temperature
range of 0...+30 °C and can be deployed, for example, in the supply of drinking water:
• Internal monitoring of delivery pipe network (local water network)
• Calculation of the bill from the main supply pipe (junctions)
• Monitoring of the water source. For example, the amount of ground water (tank inlet points,
incl. pump stations).
• Certification for the amount supplied to the delivery network (tank outlet points).
• Monitoring of the withdrawal and supply of different water works in a supply pipe (overland
supply pipe of a water network).
Resulting from incorrect use or from use other than that designated the operational safety of the
measuring devices can be suspended. The manufacturer accepts no liability for damages being
produced from this.
1.2 Installation, commissioning and operation
Note the following points:
• A calibrated Promag 51 measuring system is protected by seals on the transmitter or the sensor
connection housing from manipulation of calibration parameters. As a rule, these seals may only
be broken by a representative of the appropriate approval authorities.
• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorized to perform such work by the facil-
ity's owner-operator. The specialist must have read and understood these Operating Instructions
and must follow the instructions it contains.
• The device must be operated by persons authorized and trained by the facility's owner-operator.
Strict compliance with the instructions in the Operating Manual is mandatory.
• Hauser will be happy to assist in clarifying the chemical resistance properties of parts
wetted by special fluids, including fluids used for cleaning.
• If welding work is performed on the piping system, do not ground the welding appliance through
the Promag flowmeter.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams. The transmitter must be grounded, unless special protective measures have been
taken (e.g. galvanically isolated power supply SELV or PELV).
• Invariably, local regulations governing the opening and repair of electrical devices apply.
