More About this Item

Water velocity flowmeter consists of a protected water turbo-prop positive displacement sensor coupled with an expandable probe handle ending in a digital readout display. Meter incorporates true velocity averaging for the most accurate flow measurements. Magnetic material in the propeller tip passes a pickup point in the water velocity meter handle producing electrical impulses that are carried to the readout display by an internal cable. The flowmeter propeller rotates freely on its bearing shaft with no mechanical interconnections for minimal friction.

The turbo-prop is easily removed for cleaning or replacement. The sensor is designed to shed debris and is protected inside a 2" diameter housing. Probe housing may be placed directly on the bottom of a pipe or streambed for measuring low flows down to 2" in depth.

Large Display LCD displays average, minimum, and maximum water velocity readings. Up to 30 sets of time-and-date stamped data points can be stored in the computer with the push of a button. The water velocity computer has a water-resistant housing and incorporates a unique four-button operation for changing functions and resetting the display, and and is powered by a non-replaceable battery that will last approximately five years with normal use. Low battery and end of data warnings will also display.

A 3-foot BoPET-coated staff gauge (graduated in hundredths of a foot and centimeters) is attached to the lower section of the water velocity probe for instant water depth measurements and accurate propeller positioning. Meter is ideal for measuring flows in streams, rivers, canals, stormwater, wastewater, inflow and infiltration studies, and industrial process waters.
