Accuracy: Level: ☐.25% of actual Range or 0.04 in (1 mm), whichever is greater.Outputs: 4-20 mA Velocity and 4-20 mA Level, 1000 ohm at 24 VDC.Level Range: 1.8 to 144 in (45.8 to 3658 mm) from bottom of sensor.The Bigfoot is designed to provide water level and water velocity measurements in irrigation open channel applications and storm water applications which typically have well defined channels for more accurate area calculations.īigfoot Area Velocity Sensor Specifications: It can be mounted in irrigation pipes, channels, turn-outs, ditches, or culverts with defined dimensions. The 4-20 mA outputs can be connected to dataloggers, SCADA systems or PLC measuring systems, we like to use the CR300 or CR850.įlow can be calculated from the Bigfoot transmitter outputs by using the formula:ĬFS Flow = Area (square feet) x Velocity (Feet per/second), where Area is the cross-sectional area of the channel at the level measured by the Bigfoot, and Velocity is the speed of the water. The Bigfoot can be powered from solar charging systems using DC power supplies. This sealed, ultrasonic sensor provides a solution for continuous water measurement in open channels and partially filled pipes. Mount the Bigfoot flow sensor on the bottom of a pipe or channel to measure both water level and water velocity.
