Genuine Zenner Hot Water Meters – Threaded and Flanged Connections

Zenner hot water meters are specialized flow measurement devices designed for systems using high-temperature water, including hot water supply systems, boilers, heating systems, manufacturing plants, and industrial facilities. Designed to operate in high-temperature environments of up to 90°C or 130°C, depending on the model, Zenner hot water meters provide stable flow measurement, helping monitor water consumption and reduce losses throughout the system.

The Zenner hot water meter range is available in various sizes and connection types, including threaded meters from DN15 to DN50 and Woltman flanged meters from DN50 to DN300. This allows the products to meet the requirements of applications ranging from small hot water systems to main water supply pipelines in factories, industrial parks, and production facilities.

What Is a Zenner Hot Water Meter?

Zenner is a German water metering equipment brand known for mechanical water meters and flow measurement devices used in a wide range of applications.

Unlike conventional cold water meters, Zenner hot water meters are specifically designed to operate in high-temperature environments. Depending on the model, the meter can handle maximum operating temperatures of 90°C or 130°C.

One notable feature of this product range is the Dry Dial design. The transmission mechanism and register are isolated from the water flow, helping prevent moisture from entering the register, keeping the display easy to read, and supporting stable operation throughout the service life of the meter.

Key Features of Zenner Hot Water Meters

1. Designed for High Water Temperatures

Zenner hot water meters are suitable for systems carrying high-temperature fluids, with models designed for maximum temperatures of 90°C or 130°C, depending on the specific model.

This makes them suitable for a variety of systems, including:

• Hot water supply pipelines.

• Central hot water systems.

• Boiler systems.

• Industrial heating systems.

• Food processing plants.

• Textile and dyeing factories.

• Production systems using hot water.

2. Multiple Connection Options: Threaded and Flanged

Depending on the pipe size and required flow rate, two main product groups are available:

• Zenner threaded hot water meters: Typically used for smaller pipelines, commonly from DN15 to DN50.

• Zenner Woltman flanged hot water meters: Designed for larger pipelines and higher flow rates, commonly available from DN50 to DN300.

The availability of different connection types makes it easier to select a meter compatible with the existing pipeline system.

3. Easy-to-Read Dry Dial Design

The Dry Dial design isolates the register from the flowing medium. This is particularly important for hot water applications, where moisture and high temperatures may affect the readability of the meter display.

4. Flow Measurement for Consumption Management and Monitoring

Using a hot water flow meter allows businesses to monitor water consumption in individual areas or production processes.

The measurement data can be used to:

• Monitor hot water consumption.

• Allocate water usage costs.

• Evaluate system operating efficiency.

• Detect abnormal flow conditions.

• Support energy management and optimize operating costs.

Technical Specifications of Zenner Hot Water Meters

Depending on the product range, Zenner hot water meters may have the following reference specifications:

Note: Actual specifications depend on the specific model and product configuration. When selecting a meter, the system temperature, pressure, pipe size, and actual flow rate should be carefully checked.

Common Types of Zenner Hot Water Meters

Zenner Threaded Hot Water Meters

The threaded series features a compact design and is suitable for DN15–DN50 pipelines. It is a popular choice for hot water systems with low to medium flow rates.

Typical applications include:

• Domestic hot water systems.

• Apartment buildings and commercial buildings.

• Central hot water systems.

• Small-scale heating systems.

• Secondary pipelines in factories.

Zenner Woltman Flanged Hot Water Meters

The Woltman flanged series is designed for large-diameter pipelines and high flow rates. The flanged connection makes these meters suitable for industrial pipeline systems and main pipelines.

Typical applications include:

• Manufacturing plants.

• Industrial parks.

• Central hot water supply systems.

• Boiler systems.

• Industrial heating systems.

• High-flow hot water pipelines.

Applications of Zenner Hot Water Flow Meters

Thanks to their ability to operate in high-temperature environments, Zenner hot water meters are used in a wide range of industries and applications.

Central Hot Water Systems

The meter can be installed on hot water supply pipelines to monitor the amount of water supplied to individual areas, apartments, or consumption points.

Boiler Systems

The meter helps monitor the amount of feedwater or hot water circulating through the system, supporting operational monitoring and management.

Food Processing Plants

Hot water is widely used for cleaning, sterilization, and heating processes. Flow measurement helps businesses control water consumption for each production stage.

Textile and Dyeing Factories

Hot water is used in various treatment and heating processes in the textile and dyeing industry. Hot water flow meters help monitor water consumption and support system management.

Industrial Heating Systems

The meters can be installed on hot water pipelines used for heat exchange, heating processes, and other industrial production applications.

How to Choose the Right Zenner Hot Water Meter

To select the correct Zenner hot water meter, you should not rely solely on the pipeline diameter. The following factors should be considered together:

1. Pipeline Size

Determine the nominal pipe size (DN) to select a meter with a suitable connection size.

2. Water Temperature

This is a particularly important factor. If the system operates at high temperatures, select the correct model with the appropriate temperature rating, especially for applications above 90°C.

3. Working Pressure

Determine the actual system pressure and select an appropriate pressure rating, such as PN10, PN16, or a higher rating depending on the model.

4. Required Flow Rate

Determine the minimum, normal operating, and maximum flow rates to select a meter with a suitable measuring range.

5. Connection Type

Smaller pipelines generally use threaded hot water meters, while larger pipelines and industrial systems typically use Woltman flanged hot water meters.

Zenner Threaded or Flanged Hot Water Meter?

The choice mainly depends on the pipeline size and system flow rate.

If you are unsure which model is suitable, provide the pipeline DN size, temperature, pressure, and flow rate so the appropriate product can be recommended accurately.

Why Choose Zenner Hot Water Meters?

Compared with using a cold water meter in a hot water system, selecting a dedicated hot water meter ensures that the device operates within the temperature conditions specified by its design.

Key advantages of Zenner hot water meters include:

• Specifically designed for hot water flow measurement.

• Models available for temperatures up to 90°C or 130°C, depending on the model.
