Helical Rotary Meter

The H4000 Helical Rotary Meter is a high capacity in-line Woltmann helical rotary type meter with a precision injection moulded measurement mechanism eminently suitable for high and sustained flows associated with bulk metering. Low pressure loss characteristics are due to minimum restriction and no change in flow direction as water flows through the meter. For maintenance purposes the complete measuring mechanism may be quickly replaced with a pre-calibrated measuring mechanism, or alternatively a blank cover may be fitted, making a by-pass unnecessary in most cases.

Standard Features

The Elster Helix H4000 range exceeds Measurement Class 2 requirements of the Australian Standard AS 3565.1-1998 (Meters for cold potable water) in horizontal, vertical and inclined pipelines. Generous length integral flow straightening vanes to negate the effect of non-ideal upstream flow conditions. The counter can be rotated 359° relative to the direction of flow. Flanges drilled to Australian Standard AS 2129 Table D. (Other drill patterns available on request). Maximum working pressure 1400 kPa. Maximum working temperature 50°C. Accurate in both forward and reverse flow for network management. (To Class 2 of AS 3565.1-1998).
