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.

Cold water meters are located in every residential unit and measure the individual water consumption, for example from tap water or the washing machine. This consumption forms the basis for the water bill.

Hot water meters are used in residential 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

The picture shows a row of narrow but tall terraced houses. The terraced houses have alternating grey and white façades. On the left you can see a house with a white façade and on the far right a house with a grey façade. They are also always built at different heights, so that there are never two houses of the same height next to each other. All the houses have a large square window front in the upper half, consisting of 30 small square windows. The window front of the fourth house from the right is the only one covered by a blind. All of the houses have four individual windows under the fronts, with two on the left and two on the right below each other. Above the houses you can see the almost completely cloudless blue sky. In the foreground in front of the houses you can see a lawn with many bushes and a total of four trees, three of which can be seen on the left at the edge of the picture and one tree on the right.
