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
Practical advantages for distributors, contractors and project buyers selecting a water meter for daily metering work.
Two measuring paths
Dual-channel reading compensates for disturbed flow downstream of elbows and valves
What it means for youYou can install it in a tight plant room without the straight pipe runs a single-path meter demands, and accuracy still holds.
Nothing in the flow path
No obstruction means no head loss from the meter and nothing to foul
What it means for youNo added pressure loss for the pumps to overcome, and the meter does not become a maintenance item of its own.
Wide measuring range
Overnight minimum flow and daytime peak are measured on the same meter
What it means for youOne meter spans night leakage and daytime peak instead of you buying two to cover the range.
Long battery life
More than six years from a single lithium battery
What it means for youThe replacement cycle stays off your maintenance plan for six-plus years — no battery campaign in year two.
On-board history
24 months of stored records for loss analysis and dispute resolution
What it means for youTrace a loss or settle a dispute from the meter itself, without a logger or a site visit.
Alarms on the things that cost you
Sensor failure, over-range flow and low-voltage warnings
What it means for youYou hear about a burst, a fault or a dying battery while it is still cheap to deal with.
