    The Model 90 GEOFLO Borehole Groundwater Flowmeter is an easy-to-use portable instrument, capable of direct measurement of water flow rates in rock boreholes. This extremely sensitive flowmeter operates on heat-pulse principles. The direct readings, displayed on the screen of the laptop computer as ml/min upflow or downflow, eliminate the need for tedious dye and salt tracer tests. The flowmeter gives measurements within five minutes and is capable of taking as many as 80 field measurements per day.

    The Model 90 GEOFLO Borehole Groundwater Flowmeter consists of a probe with cable length up to 450 ft (150 m), an interface box, and a laptop computer (customer- or vendor-supplied), plus interlocking aluminum rods for lowering the probe into the borehole or well. A pneumatic packer is used for easy insertion into boreholes. The unit may be used in 2-inch up to 8-inch diameter boreholes or vertical wells.

    KVA flowmeters are used for inflow-outflow analysis, fracture zone location, well-screen positioning, grouting requirements, and recharge zone determination. They are also useful in oil and hazardous waste investigations and remediation.
