Smart Prepaid switchable post-payment mode keypad type Water Meter

The STW36-A water meter is a prepaid model, but can switch to a post-paid model of water meters.

Prepaid means that users must first pay for a certain service according to the amount they want to use before using it. For example, if our water meter users want to use 1 ton of water, they have to pay for 1 ton of water on our Vending platform, get a receipt, input 20 Tokens, and then use the water. Once the fee is used up, the meter will turn off automatically and the customer will not be able to use it again without paying the fee. This type of payment method is mainly used for customers who do not have self-control. because in some areas, due to the limited living standard, some users will default in payment of water fee. But the post-payment water meter will not automatically close the valve after use, so many users will default or even refuse to pay the fee after use. This will cause great losses to the supplier, often can not collect the fees to change. And prepaid water meters, a good solution to these problems. If you pay for the amount of water you use before you use it, you don’t need to pay for it. Convenient but also save manpower and material resources.And our water meter can be prepaid and post-paid two modes to switch, as long as the corresponding input code can be broken. In the way, no matter in which region, no matter what kind of payment model customers need, our water meter can be realized, both convenient and fast.
