Tailored to your needs, ista offers you high-performance cold water meters and hot water meters including comprehensive service. Whether radio, M-Bus or contact technology, whether for flats, houses or for large-scale water: we have the right solution for every area of application.
Water meters for accurate billing according to consumption
At ista, all flat, house or large water meters are available for both cold water and hot water. The precise measuring technology of ista water meters makes it possible to record water consumption exactly and to bill according to consumption. This means that you can no longer miss even the smallest withdrawals when billing, for example due to dripping taps.
Residential water meter
ista offers two modular residential water meters for consumption-based billing in flats. In the basic version, our water meter is supplied with a plug-in empty module. It can be easily removed at any time and replaced with another module. This means that the device can be used in three versions: as a contact, radio or M-Bus water meter. As dry-running meters, our water meters also enable increased operating and measuring accuracy, as the register does not come into contact with the flowing water. This prevents deposits in the register.
Areas of application
Depending on the accessories, the following types of installation are possible: flush-mounted, surface-mounted at the washstand or at the kitchen sink.
