HWE WOLTMAN WATER METER
HWE Woltman Water Meters are designed for accurate measurement of high-volume water flow in transmission lines, distribution networks, industrial plants, water treatment plants (WTP), sewage treatment plants (STP), irrigation systems, and municipal water supply schemes.
The meter operates on the Woltman turbine principle, where water flow rotates a turbine positioned in the flow stream. The rotational speed is directly proportional to the flow rate, ensuring reliable and precise measurement over a wide operating range.
Key Features
- High accuracy and repeatability
- Suitable for large diameter pipelines
- Low pressure loss across the meter
- Robust cast iron body construction
- Epoxy-coated body for corrosion resistance
- Magnetic drive mechanism
- Dry dial register for clear reading
- Available with pulse output for remote monitoring
- Long service life with minimal maintenance
- Conforms to relevant international standards
Applications
- Municipal Water Supply Networks
- Water Treatment Plants (WTP)
- Sewage Treatment Plants (STP)
- Industrial Water Distribution Systems
- Irrigation Projects
- Cooling Water Systems
- Commercial Complexes
- Residential Townships
- Bulk Water Measurement Stations
Working Principle
The Woltman Water Meter consists of a turbine rotor installed in the flow path. As water passes through the meter, it drives the turbine at a speed proportional to the flow rate. The turbine rotation is transmitted magnetically to the register, which records the total volume of water passing through the pipeline.
This design provides accurate measurement while minimizing mechanical wear and maintaining long-term reliability.
