Single-jet water meters

Single-jet water meters - precise measurement of water consumption

Single-jet water meters are   key measuring devices in water supply systems . They are used to precisely measure the amount of water flowing. At Onninen we offer a wide selection of these precise instruments. Our offer includes the renowned brands Bmeters and Apator-Powogaz. We provide comprehensive solutions for various applications.

Single-jet water meters are distinguished by their simple design. They operate on the basis of a single stream of water. It flows through the measuring chamber, setting the rotor in motion. The rotor revolutions are proportional to the volume of flowing water. The mechanism counts these revolutions and shows the result on the counter. This   a reliable and economical way to measure water consumption .

Types of single-jet water meters in the Onninen offer

In our assortment you will find various types of these devices:

• Cold water meters
• Water meters for hot water
• Pulse output models
• Versions adapted for remote reading

Each type has its own unique features and applications. Cold water meters are resistant to low temperatures. Hot water models can withstand higher medium temperatures. Pulse output versions allow automatic reading. They facilitate integration with building management systems.

We often come across questions about the differences between these types . The key is to match the water meter to the specific operating conditions. Water temperature, quality, and installation requirements are important. Our experts will be happy to advise you on choosing the right model.

Criteria for selecting single-jet water meters

Choosing the right water meter is a key issue. It affects the accuracy of measurements and the durability of the installation. When choosing a device, several important parameters should be taken into account:

• Nominal flow (Q3)
• Nominal connection diameter
• Metrology class
• Operating temperature
• Mounting position (horizontal/vertical)

Our experience shows that proper selection is essential . An inappropriate water meter may give inaccurate readings. It may also wear out faster. That is why we always recommend consulting our specialists before purchasing.

Nominal flow (Q3) is a key parameter. It determines the optimal operating range of the water meter. It should be selected for the actual water consumption in the facility. Too small Q3 can lead to device overload. Too large - to inaccurate measurements at low flows.

The nominal diameter of the connection must correspond to the installation. The most commonly used are DN15 and DN20. In larger facilities, larger diameters may be needed. The metrological class informs about the accuracy of the measurement. A higher class means better precision, especially at small flows.

The operating temperature is an important aspect. Cold water meters usually operate up to 30°C. Hot water models can withstand temperatures up to 90°C. The mounting position is also important. Some water meters are only designed for horizontal mounting.

Applications of single-jet water meters

Single-jet water meters are widely used. They can be found in various types of facilities and installations.   They are most often used in residential construction . They are installed in single-family houses and apartments. They are used for individual billing of water consumption.

In multi-family buildings, they are often used as sub-meters. They enable precise settlement of water costs between tenants. This is a fair and transparent solution. It also motivates economical water management.

Single-jet water meters also work well in commercial facilities. They are used in offices, shops or service premises. They allow for precise settlement of costs between tenants. This is important in the case of facilities with many users.

They are also used in light industry. They are used to measure water consumption in production processes. They help to optimize costs and control media consumption. This is important for effective management of the company.

We recently used these water meters in a project for a large housing estate . The client needed a solution for individual settlement of apartments. We chose models with the possibility of remote reading. This improved the process of data collection and settlement.

In the case of office reorganization, we most often recommend models with a pulse output. They enable integration with the building management system. This allows for automatic collection of consumption data. This is a convenient solution for property managers.

Single-jet water meters are also useful in small manufacturing plants. They help monitor water consumption in individual processes. This makes it easier to detect any leaks or irregularities.

In our daily practice, we see a growing interest in these devices. Customers appreciate their simplicity and reliability. They are also increasingly asking about models with remote reading capabilities. This is a trend related to the development of intelligent buildings.

Onninen recommends single-jet water meters as the basic measurement solution. They are economical and proven in operation. We offer models adapted to different needs and working conditions. Our experts will be happy to help you choose the right device.

We invite you to familiarize yourself with our full offer of single-jet water meters. You will find devices from renowned manufacturers. We guarantee professional advice and technical support. Together we will select the optimal solution for each installation.
