Who Buys It
The same technology is bought for different reasons depending on who is signing.
Revenue collected before water is used — the token closes the valve at zero, so arrears stop growing this budget cycle.
No more door-to-door collection rounds. Tenants load credit themselves and the account is settled the moment they pay.
STS certification answers the technical clauses of most tender documents, and battery power means no cabling on site.
STS is a hard requirement in many African and Southeast Asian tenders — with certified stock you can quote those documents the day they open.
Size from the measured demand, not from the pipe diameter. A meter one size down from the flange usually reads better across the real flow range.
Yes. Fit one, test it on your own bench, and the bulk order follows your result rather than our description of it.
Yes — dial face, nameplate, model numbering and packaging can carry your brand. Tell us at enquiry so it is built in rather than added on.
Calibration and test records filed against your order, plus packing list, commercial invoice, certificate of origin and bill of lading.
Two fields are enough for us to come back with the models that fit.
