Flow Sensors and Transmitters

Flow Sensing for Maxicom2®, SiteControl™ and ESP-LXD

Reliable and simple flow sensors for use with Rain Bird Maxicom, SiteControl and ESP-LXD central control systems.

Rain Bird flow sensors send flow data to central control or stand-alone control systems for precise and accurate flow monitoring.

For (Hard Wire) Two-Wire Satellite Systems (Maxicom2 and SiteControl), the Flow Sensor is installed with a Pulse Transmitter and a Rain Bird Pulse Decoder (DECPULLR).

For Link Radio Satellite Systems (Maxicom2 and SiteControl), the Flow Sensor is installed with a Pulse Transmitter (no decoder required).

For SiteControl Decoder Systems, the Flow Sensor is installed with a Pulse Transmitter and a Two-Wire Decoder Sensor Decoder (SD210TURF).

For ESP-LXD Decoder Systems, the Flow Sensor is installed with a Two-Wire Decoder Sensor Decoder (SD210TURF) - no pulse transmitter required.

Surge protection (FSSURKIT) is recommended for all systems - One at the Flow Sensor, and if more than 50' of wire run, one at the Pulse Transmitter.

Suggested Operating Range

The following table indicates the suggested flow range for Rain Bird Flow Sensors. Rain Bird Sensors will operate both above and below the indicated flow rate. However, good design practice dictates the use of this range for best performance. Sensors should be sized for flow rather than pipe size.
