cold water meter

1/2 "-2" cast iron body dry dial multi-jet water flow meter

multiple jet water meter, the operating principle is based on a system that forces the passage of the incoming water through a precise series of open pipes in a capsule. This represents the distributor, which contains the turbine inside. The water inlet produces a series of symmetrical jets, which constantly impact the turbine, which thus remains in equilibrium.

1/2" -2" cast iron body dry dial multi-jet water flow meter




Terminology interpretation


A single jet meter has an operating principle based on the tangential incidence of a single water jet with a particular turbine. This is mounted inside the counter body, in a radial position. The rotary motion of the turbine transmits the necessary motion to the meter. This is what allows the measurement of the volume of water that is transited through the meter

In the case of a multiple jet counter, on the other hand, the operating principle is based on a system that forces the passage of the incoming water through a precise series of open pipes in a capsule. This represents the distributor, which contains the turbine inside. The water inlet produces a series of symmetrical jets, which constantly impact the turbine, which thus remains in equilibrium.





Wet, dry and semi-dry dial counter

The wet dial counter is completely immersed in the circulating water. The rollers are instead contained in a separate and perfectly sealed capsule. The transmission therefore passes from the turbine to the gears.

The dry dial counter has a hermetically sealed meter from the section in which the water flow is present. This area therefore remains completely dry. Given the separation, the transmission takes place exclusively through a magnetic coupling between the same meter making and the turbine.

The semi-dry (or semi-dry) dial counter owes this definition to the roll chamber filled with liquid, with a section of the sealed dial, in order to protect from any kind of penetration, of dust, moisture or liquid, the innermost parts of the system.



Counter with remote reading

The counter with remote reading uses a remote control system, which allows to monitor and pilot the technological installations at a distance in private users. All this makes it possible to optimize the performance of the systems in the home, increasing both their safety and efficiency. All this therefore leads to a reduction in costs .

Thanks to the automation of the management, an automatic real-time control of the network is possible , as well as the management of every necessary maneuver, such as the remote management of alarms for example. In this way a 24 hour surveillance of the water network and the tanks is guaranteed, also guaranteeing the quality of the water that is consumed day after day.

Water consumption can be controlled remotely, in order to make the process easier and the general management more transparent for the user. In this way it is also possible to view any losses due to breakages in parts of the plant in the subsoil or under the flooring.
