For a card-based project, the software, reader, cards and meters must work together.
01
Vend the Credit
Use the compatible water-vending software.
02
Write the Card
Use a matching reader and project card.
03
Load at the Meter
Insert or present the card, depending on the model.
04
Use & Monitor
The meter deducts credit and manages its valve.
Bluetooth, infrared and wired projects use their own matching devices and software. Share your existing system details so compatibility can be reviewed.

Frequently Asked Questions
Recharge, compatibility and installation questions for prepaid-meter projects.
What is the difference between insert-card and contactless meters?
An insert-card meter uses physical card contact to load credit. A contactless model reads the card at a sensing area. Both support a prepaid workflow; the card and reader must match the selected system.
What happens when the balance runs low or is used up?
Low-balance alerts prompt users to recharge; the valve closes when the available credit or water allowance is exhausted. Ask for the threshold settings and recharge / reopening sequence for your project.
Can we use our existing cards or vending software?
Compatibility must be checked. Share your card type, reader, software and interface requirements before ordering. An IC-card label alone does not establish compatibility with another supplier’s system.
Are tiered tariffs and power-loss valve closure standard?
Tiered tariffs, minimum-consumption charging and power-loss valve closure are customizable functions. Include the functions and billing rules you need in your project inquiry.
Which version should we consider for a damp meter well?
A split electronic unit provides easier access in damp locations; the dedicated IP68 non-contact design offers a sealed alternative for demanding environments. These are different solutions; do not assume every recharge method is available in both designs.
Can every model use Bluetooth, infrared and a wired connection?
No. These are different recharge and communication routes. Select a matching model and supporting system rather than treating every interface as standard on one meter.
What sizes are listed for small-diameter prepaid meters?
General small-diameter LXSK dimensions are listed here for DN15, DN20 and DN25, plus dedicated vertical contact-card dimensions for DN15 and DN20. Those general tables do not establish the size availability of every special version.
