Discover Our Range of Water Meters for Any Application domaqua®m & istameter®m.

At ista, we offer a complete range of water meters for all types of properties, whether it's apartments, houses, or bulk water meters, for both hot and cold water. Our water meters are equipped with precise measuring technology that accurately records water consumption and allows for consumption-based billing. This ensures that even the slightest withdrawals, such as from dripping taps, are accounted for in the billing process.

Hot water meters are used in property units if the hot water is heated centrally in the boiler in the basement. This ensures that the hot water costs can be billed fairly according to consumption in the heating bill.

Wireless Data Collection

Remotely collects consumption data without entering any property

M-Bus System

Central recording of Heat and water consumption

Modular System for many application areas

For example as flush and surface mounted meter

The picture shows a modern, open-plan office space where two people are standing in the center of the room. In the background on the left are cupboards containing files and a presentation board. To the right, you can see two white walls raised close together that do not reach the ceiling of the room. A railing is attached to the right-hand wall, which extends to the right-hand side of the picture and to the wall there. The wall of the railing itself is made of a grey grid and the floor is attached to a steel beam that can be seen from the side. The lattice provides a clear view of the black wall behind it. Two large desks can be seen in the center of this elevation, with two chairs on either side. On the right-hand side, against the brick wall, there is another desk with a chair and a passageway in the wall. In the foreground you can see two people walking towards the cupboards on the left. These two people are only vaguely recognizable as they are in motion and therefore blurry. In front of the railing in the center of the picture are two large tables that have been placed opposite each other and form a large group of tables. There are two chairs to the left and right of the group of tables. Three plants can be seen on the right-hand edge of the picture, their branches protruding into the picture. In the center of the picture, a younger man is standing next to a younger woman, right before the group of tables. The man has short black hair and a black beard and is wearing a black jacket with grey trousers and brown shoes. The woman has open red wavy hair and is wearing a white blouse, a grey metallic skirt and white pumps. They are both smiling while the woman has a tablet in her hand and is presenting the smart metering options from ista to the man.
