H2Flow Controls LevelSmart Replacement Water Level Sensor

The H2Flow Controls LSRS is the replacement water level sensor for the LevelSmart wireless autofill system. It is the part that lives in the pool; the valve controller at the equipment pad is separate.

How it works

The sensor is positioned in the pool at the water level you want to hold. Every 30 minutes it wakes up, measures the current level and sends that reading wirelessly to the LevelSmart valve controller. If the water is low, the controller opens the fill valve for 7 minutes, then the sensor goes back to checking every 30 minutes until the level is right.

When to replace it

If your LevelSmart controller has stopped receiving readings or the pool is no longer topping up on its own, the sensor is the usual suspect. This is the same LSRS sensor the system shipped with, so it pairs with the existing controller.
