Water Meter
The PPLA23UN encompasses a stylish dial panel for clear meter reading and easy maintenance and consists of:
- Water Meter
- STS Keypad Customer Interface Unit (CIU)
Using Radio Frequency Communication Technology, the STS meter communicates conveniently with its CIU to recharge the meter, request a balance and several other functions which provide comprehensive, reliable and advanced prepaid solutions to both landlords and tenants.
This meter is compatible with both velocity and volumetric flow rates and complies with OIMLR49, ISO4064 and conforms to STS standard protocol. Moreover the meter supports Anti-magnetic interference and Meter Cover open detection. If the meter cover is opened the valve will close automatically. The shut-off valve will close to stop the flow of water once credit is exhausted.
