- Woltman Helix Water Meter (Vertical Installation)
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.
