H-3521 Fluid Pressure Sensor
The WaterLOG® H-3521 “Fluid” is a SDI-12 compatible, NIST traceable pressure sensor. The sensor can directly measure water, antifreeze or other fluid pressure with an accuracy better than 0.05% FSO.

 
Key Features
 Directly measure water, glycol or fluid pressure
 Works with rain gauges, snow pillows, artesian wells, piezometers and water tank
 Ideal for industrial applications such as monitoring culinary water pressure
 Pressure accuracy is 0.05% full scale
 Accuracy over temperature range exceeds ±0.02 ft. (6mm) of water
 Built-in temperature compensation
 Operating temperature range -30 to +60C
 SDI-12 output provides measurement data in engineering units such as feet or meters
 Industrial outputs: 4-20mA and Modbus RTU
 Enclosure is nonconductive and corrosion proof
 Low current operation (150uA standby)
 Extended SDI-12 command for setting the Stage to the current water elevation or pressure
