Global Water Flow Probes

Now includes a Mylar-coated staff gauge for reading water depth.

The Flow Probe is a highly accurate, lightweight water velocity instrument that is excellent for storm water runoff studies, measuring flows in streams, rivers and partially filled pipes. The anodized aluminum telescoping handle is available in lengths that extend from 3 - 6' and from 5 - 15'. The key feature is a unique, free rotating turbo-prop propeller sensor protected inside a 2"-dia. PVC housing. The housing may be placed directly on the bottom of pipes or streams for measuring flows down to 2" in depth. The unit may be extended up to 25'L for measuring sewers and from bridges using standard PVC pipe and electrical extension cable.

A 3'L Mylar-coated staff gauge graduated in hundredths and centimeters is attached directly to the lower section of the probe for instantly measuring water depth and probe position. The waterproof digital readout, located on the top of the handle, displays instantaneous velocity as well as true velocity averaging. Two-button keypad also allows readout of maximum velocity, time, chronometer and totalizer. Easily replaced internal watch-type batteries power the unit for up to one year.
Each Flow Probe is shipped complete in a padded carrying case. Carrying Case: 9"W x 4"H x 4'L.
