Advantages of Volumetric Rotary Piston Water Meter

High durability

Woltman Water Meter meters are made of robust materials, such as brass, stainless steel, or cast iron, that can withstand corrosion, abrasion, and wear and tear.

High capacity

Woltman Water Meter meters can handle high flow rates, ranging from 1.5 to 10,000 cubic meters per hour. They can also operate at high pressures, up to 16 bar. This makes them suitable for applications that demand large volumes of water, such as irrigation, cooling systems, fire protection, and water supply networks.

High flexibility

Woltman Water Meter meters can be installed in various positions and orientations, such as horizontal, vertical, or inclined. They can also be equipped with different accessories and features, such as pulse output, remote reading, data logging, and tamper detection.

Types of Woltman Water Meter

Horizontal Woltman Meter

In this configuration, the meter's turbine rotates horizontally in alignment with the flow of water. This design is suitable for situations where installation space is limited, and the flow direction remains consistent.

Vertical Woltman Meter

In the vertical variant, the turbine rotates vertically, perpendicular to the water flow. This design offers versatility, as it can accommodate changes in flow direction. Vertical Woltman meters are often preferred for applications where installation flexibility is crucial.

Features of Woltman Water Meter

No worm gear transmission mechanism, the impeller direct drive counter, transmission efficiency, low initial flow.

Wide range, suitable for large changes in traffic occasions.

Full flow detection, high precision measurement.

Dry magnetic structure, to ensure that the counter clean, clear display.

Six-digit increase in digital character wheel display readings, reading more clearly.

Removable measuring movement structure, easy maintenance.

Internal adjustable structure, to prevent unauthorized regulation.

Built-in stainless steel filter, the effective protection of measuring institutions.

High wear-resistant bearing system ensures long-term product stability and reliability.

Optional tamper protection cover. (To prevent damage or change the measurement structure, anti-theft effect).

Components of Woltman Water Meter

A body, a measuring insert, and a register. The body is made of metal and has flanges or threads for connecting to the pipe. The measuring insert contains the turbine and a transmission mechanism that transfers the rotation to the register. The register is a device that displays the total volume of water that has passed through the meter.

Woltman Water Meter Installation Steps

Install inline strainer upstream to protect the impeller.

Mount the meter horizontally or vertically, ensuring upward flow if not horizontal.

Ensure adequate straight pipe runs and secure flanges per specifications.

Connect pulse or communication modules (e.g., NB-IoT, M-Bus, RS485) for remote reading.

Applications of Woltman Water Meter

Industrial Settings: Industries with high water consumption, such as manufacturing plants, power generation facilities, and mining operations, rely on Woltman Water Meter to monitor and manage their water usage efficiently.

Agriculture: In large-scale agricultural operations that require substantial water supply for irrigation, Woltman Water Meter meters provide accurate measurements essential for efficient resource allocation.

Municipal Water Distribution: Woltman Water Meter play a crucial role in measuring water consumption within municipal water distribution networks, ensuring equitable billing and resource management.

Fire Hydrant Testing: Fire departments utilize Woltman Water Meter to assess the flow capacity of fire hydrants, enabling them to determine firefighting capabilities accurately.

FAQ

Q: What is a Woltman type?

A: A Woltman-type cold water meter is a large-volume, velocity-based flow meter used primarily in industrial, agricultural, and municipal applications to measure high flow rates.

Q: Is it a good idea to have a smart water meter?

A: Benefits and how they affect your bill
More accurate bills based on actual water use. Your water company will alert you to leaks to prevent water waste and high bills. Better for the environment by helping you to understand and reduce water use and spot leaks.

Q: How many years does a water meter last?

A: About 15-20 years
Water meters, like any other mechanical device, have a lifespan. They typically last for about 15-20 years, but this can vary depending on the type of meter, the quality of the water, and the environmental conditions.

Q: How to check water quality meter?

A: Turn on the meter and remove the protective cap. Dip the meter in a glass of your tap water. Wait for the reading to stabilize. Note down the TDS value in parts per million (ppm).

Q: How often should I check my water meter?

A: If you have a water meter, it should be read at least once a year, and read by your water company at least once every two years. Some water companies might read your meter more frequently. Often the water meter is installed so that your company can read the meter remotely.

Q: How do I identify a leak using my water meter?

A: Near or at the center of the meter display is a colored triangle or asterisk. This triangle or asterisk is sensitive to water flowing through the meter and can be used to detect leaks.

Q: How often do water meters need to be calibrated?

A: Once a year
Install master meters at all water sources (produced or purchased) and test at least once a year and calibrate as necessary to the printed recommendations of the meter manufacturer.
