Wallace & Tiernan Metal Tube Variable Area Flowmeter
Metal Tube Varea-Meter® Variable Flow Meters are designed for the measurement of high-volume flows of aggressive liquids and gases. The advanced design of the float and the tapered tube extends the meter capacity to match that of comparable meters costing much more. The 316 stainless steel construction makes these meters suitable for a broad spectrum of applications.
Metal Tube Varea-Meter® Variable Flow Meters are easy to install, calibrate and configure. They provide reliable long term performance in gas or liquid service. Available in a variety of tube sizes (½-, ¾-, 1-, and 1½ inches) and flange facings and ratings, these flow meters measure over a 10:1 range for aggressive fluids at high temperatures and pressures. Metering accuracy is 2% of full scale.
Anti-Magnetic Particle Float has a reduced flux density and is located above the metering disk. This discourages accumulation of magnetic particles, especially on the disk edge where they can cause errors in indication. Meter design directs the flow into a pattern, which scrubs the float and guides clean. The Metal Tube Varea-Meter® unit is ideal for suspensions and slurries.
When the float is at rest, nothing projects beyond the flanges. Spool pieces are not required for installation and a frequent cause of damage when removing meters from a line is gone. In and out piping is vertical.
For reliable indication, a powerful magnetic linkage exists between the float magnet and the indicator magnets. Transmission and indication are reliable even under sudden flow surges.
The indicator unit, with optional 4-20mA transmitter or flow switch, are independent. A mounting clamp attaches each to the meter tube. The same clamp attaches the transmitter or flow switch 180 degrees from the indicator unit. Clearance between any of these units and the tube leaves room for steam or electric tracing.
