Bulk water meter with dry dial
Stepping away from the conventional, our Woltman helix water meter with vertical installation brings a fresh perspective to large-diameter pipeline metering. This meter is known for its dynamic flow handling and minimal pressure impact. When water courses through this meter, it drives the uniquely shaped helical impeller in an axial flow, converting the water's velocity into a quantifiable volume displayed on the meter.
Applications
- From the kitchen to the bathroom, Woltman helix water meters are ideal for metering household water usage.
- Tracks water flow in commercial establishments and light industrial facilities.
- These water meters are a reliable choice for water measurement in schools, hospitals, and other public institutions.
