Electricity Meter Selector Switch

Customer: SIPA Verteilanlagen AG

The meter selector-switch for washing-machines consists of two components, the control unit installed in the power distributor and the card reader, which is mounted next to the washing facilities. The meter selector-switch is operated by individual key-cards assigned to each tenant.

  • WZU Contactless System

    The controller is installed at the power distributor and provides the switching between meters. When a washing machine is activated by a card reader, the meter is switched to the counter of the correct apartment, charging the account of the respective user.

  • Card reader

    The card reader is the interface to the user. An intuitive design allows easy operation: simply put the card into the card reader and remove it when the wash cycle is finished.

  • Keycard

    The keycard cannot be manipulated or copied, preventing use of the system by unauthorised people. It can also be easily blocked and replaced, if lost or stolen.

Optical Reader

Customer: Aquametro AG

Aquareader® is an optical read-out module for water meters, that on request automatically reads identification number, nominal diameter, fluid and the current meter reading via M-BUS or CS interface. The device configures itself automatically within 30 seconds after installation using the data stored on the RFID chip built into the cover and does not require a battery as it is supplied with energy when connected to a powered bus.

Aquareader Display

Aquareader® is available with three connection options: two connector types for BKW and Volga, plus one version which allows connection of a cable (enables IP68).
