ARAD WST Pulse Kit

The ARAD WST pulse kit is essential for connecting your meter to an BMS system. To install, replace the existing dial with the pulse-ready dial that includes a convenient mounting point for the pulse lead.
This ARAD pulse kit can be retrofitted while the meter remains inline, eliminating the need to shut off the water supply.

Note: New ARAD WST meters come standard with a pulse kit pre installed.
