Smart water meters by QUNDIS.

QUNDIS water meters at a glance

QUNDIS supplies both mechanical and electronic water meters. These products – called Q water – reliably record the cold and hot water consumption within the building. Depending on the type of device and installation material, all our devices can be integrated with the water pipe on the surface or in the wall.

Our metering instruments offer great advantages for metering service providers and end users: thanks to our radio add-on modules, mechanical water meters can also be used for the complete automation of consumption data acquisition. All our meters offer optimum protection against tampering of any kind.

Benefits

Simplified annual billing

Automation of remote meter reading thanks to innovative radio technology.

Standardised interfaces

And therefore suited to practically every application.

Precise metering

Certified measurement and testing facilities guarantee the metering accuracy of our water meters

Transparent metering

Information and meter readings for tenants can be viewed on the display at any time, and even retrospectively in the case of electronic models

Upgradable and flexible

Mechanical meters can be upgraded with radio technology or a complete system change (e.g. from walk-by to AMR readout) at any time.

The various types of water meter

We distinguish between mechanical and electronic water meters in our Q water products. The various advantages and disadvantages are outlined here:

Electronic water meters

  • Annual consumption values are automatically saved on the readout date
  • More transparency for tenants (they can check the stored values on the display)
  • Various displays possible
  • Monthly statistics are transmitted automatically
  • Analysis of consumption behaviour possible
  • Easy error detection by algorithms (e.g.: leaks are quickly detected)
  • Tamper proof

Mechanical water meters

  • Readout must be on the scheduled day
  • The roller counter only shows the current reading
  • Counts forwards and backwards
  • Tamper proof
  • Inexpensive to buy
  • Upgradeable with QUNDIS radio add-on modul
  • Extendable functions: storage of monthly statistics, automatic transfer of the annual consumption on the scheduled date

FAQ

What is the meaning of the numbers and symbols on the display of the electronic water meter?

We offer various types of electronic water meter. The data sheets on our website will explain to you what appears in the display of your water meter.
