WaterLOG® H-340-SDI
Tipping Bucket Rain Gauge with SDI-12
Specifications


General
Sensor: Tipping bucket with magnetic reed switch sensor

Accuracy/ Rainfall Rate
Built in microprocessor measures the time between bucket tips (rainfall rate) and uses this data to compute the bucket volume per tip at the current rainfall rate. A built-in math polynomial provides corrected bucket volume for rainfall rates between 0 and 25 in/hour.
Resolution: 0.01 Inches
Rain fall rate: 0 to 25 inches/hour (calibrated)

SDI-12 Output
Baud Rate: 1200
Protocol: SDI-12, 7-bit even parity, 1 stop bit.
Output Voltage Levels:  
   minimum high level: 3.5 volts
   maximum low level: 0.8 volts
   maximum cable length: 250 ft.
SDI-12 Output Data Parameters:  
   1: Accumulated rainfall since last measurement  
   2: Raw bucket count since last measurement  
   3: Total accumulation  
   4: Total daily accumulation (today)  
   5: Total daily accumulation (yesterday)  

Automatic daily accumulation using built-in crystal controlled time of day clock.

Power Requirements
Voltage Input: 10.0 to 16.0 Volts DC
Current:  
   Standby: 150uA typical
   Raining: 3.7mA for 60 seconds
   Communicating: 9.8mA
