VISI-RATE - Low Cost Flowmeters and Flow IndicatorsA compact, rugged line of low-cost flow rate meters and flow indicators to place a new twist on the way you measure flow.
- Superior Readability
- The extra long 3-1/2" [90 mm] scale provides excellent flow rate measuring resolution compared to competitive products. Dual measuring units — U.S. (GPM) and Metric (LPM) graduations are standard.
- Compact and Rugged
- VISI-RATE's tough polysulphone construction measures less than 5 inches (125 mm) long and 1-1/2 inches (38 mm) in diameter, making it suitable for permanent installation in lubrication, cooling and hydraulic pump case drain systems.
- Mount in Any Orientation
- VISI-RATE will provide stable, accurate readings when mounted in any piping orientation.
- Inspect the Fluid
- The transparent body of the meter permits visual inspection of fluid conditions. Excessive aeration, contamination or discoloration can be diagnosed "at a glance".
- Sensing Method
- VISI-RATE's patented (Pat. No. 4,393,723) helical-torque sensing method assures measurement accuracy of better than 95% of actual flow rates - even with variable fluid parameters.
Operating Theory
The VISI-RATE flowmeter has a low mass axial turbine which is urged towards zero flow rate by a precision torsion spring. As the fluid flows past the turbine blades, a rotational torque is imposed onto the turbine and spring causing the turbine to rotate to a position where the spring's return force equals the fluid torque. Since variable fluid flow rate causes variable fluid torque, flow rate is measured by correlating turbine rotational displacement to flow rate. A dual reading measurement scale, GPM and LPM, is imprinted on the circumference of the turbine. Simply aligning the scale with the stationary pointer on the meter body provides positive flow rate readings.
The VISI-RATE flow indicator operates without the torsion spring, allowing the turbine to spin freely within the fluid stream. A chart appears on the side of the VRI flow indicator and approximates turbine RPM to GPM/LPM. Flow rates as low as 0.2 GPM (0.8 LPM) can be reliably indicated.
