Dual-channel Ultrasonic Bulk Water Meter CSW
Two ultrasonic paths from DN50 to DN200, so turbulent or disturbed flow still measures accurately on a large main.
Product overview
On a large main, flow is rarely clean and symmetrical — elbows, valves and reducers leave the profile distorted. The dual-channel CSW reads two acoustic paths through the same body, which averages out that distortion and holds accuracy where a single-path meter would drift.
It is specified for district metered area boundaries, large commercial complexes and industrial inlets, where the meter has to be trusted for loss accounting and for billing between two parties.
Key benefits
What this model does for the people who specify it, install it and pay for it.
Two measurement paths
Dual-channel reading compensates for flow disturbance downstream of elbows and valves.
No obstruction in the pipe
Nothing in the flow path means no head loss from the meter and nothing to foul.
Wide measuring range
Handles both overnight minimum flow and daytime peak on the same meter.
Long battery life
More than six years from a single lithium battery.
On-board history
24 months of stored records for loss analysis and dispute resolution.
Alarm functions
Sensor failure, over-range flow and low-voltage warnings.
