FP101/201 Flow Probe

The FP101 Flow Probe is a easy to use water velocity instruments for measuring flows in open channels and partially filled pipes. The Flow Probe consists of a protected turboprop positive displacement sensor coupled by an expandable telescoping probe handle (3 to 6 ft. or 5 to 15 ft.) to a digital readout display. The digital readout display receives an electrical signal from the propeller, amplifies the signal, and converts the reading to feet per second (or meters per second). The readout unit is water resistant and incorporates a unique two button operation for changing functions and zeroing the display. The Readout displays instantaneous velocity and true average velocity. When the readout is zeroed by pushing both buttons or when the probe is inserted into flowing water, a running average is started. As long as the probe remains in the flow, the averaging continues. Once the average reading becomes steady, the true average velocity has been obtained. When you pull the probe from the water, this average value is frozen on the display until reset. The probe housing may be placed directly on the bottom of pipes or stream beds for measuring low flows down to 2" in depth. Specifications
