Using a camera modified to accept the FloVi- F <br /> Won device,visual observations and cable movement are used toT �I�Tquantify fluid rate and direction. Highly accurate in clear wa- LO 1ON <br /> ter,especially with recent refinements,FloVision provides a re- <br /> liable alternative to the mechanical flowmeter and the heat <br /> pulse flowmeter. <br /> FloVision measures down to .1-2 feet per minute of VERTICAL WA'CER FLOW MEASURING DEVICE <br /> fluid movement and can be repeated accurately. <br /> Measurements UPPLOW NO FLOW DOWNFLOW <br /> • Visual Measurement of Fluid Velocity and <br /> Direction <br /> ' wa rauv spa wW WS MEASMM <br /> i <br /> Applications <br /> • Flow measurement within the borehole TOP VIEW SIDE VIEW <br /> • Identification of permeable zones <br /> Operating Conditions <br /> • Fluid filled open hole <br /> • Minimum borehole size -2.00 Inches <br /> • Maximum borehole size- None <br /> 0 Maximum borehole depth - 6000 Feet <br />
