Variable Area Flow Meters

46 Products
Direct Reading Analog Display Flow Meters

The FL-W7100 Series uses a basic variable-area flowmeter design: a float and tapered tube. As a result, these meters have longer, linear scales and good pointer stability.

Variable Area In-line Flow Meters For Air

The FLMG flow meters feature rugged construction and direct-reading flow rates of air. The units are calibrated at 100 psi pressure, idea for most compressed air applications.

Easy-view Flow Meters For Water and Oil

The OMEGA's FL-9000 EZ-View flowmeters provide accurate, in-line indication of oil or water flow rates at an economical cost and can be mounted with no straight pipe runs

Easy-View Flow Meters with Adjustable Flow Alarm

The FL9000-AC flowmeters are ideal for a wide range of flow monitoring applications. Additional features include an adjustable flow alarm externally mounted on the meter.

Variable Area Flow Meter for Accurate Measurement of Air and Liquids

The OMEGA's precision variable-area flow meters for air, water, and gases have up to ± 2% of full scale accuracy. (Models ending in "07" or "45" have ± 5% FS accuracy).

Heavy Duty Flowmeters With Stainless Steel Enclosures

The Omega FL900 series are heavy duty flowmeter with SS enclosures, unique float stop design allowing internals to be reomoved and replaced without disturbing the tube.

Variable Area Flow Meter For Liquids

Made of PTFE, PFA, and PCTFE, the Model FL-10 liquid flow meter is excellent for high-purity flow applications or with corrosive liquids. Available with or without a valve.

High Accuracy Stainless Steel Variable Area Flow Meters

In-line Variable Area Flow Meters

OMEGA's FL-6400A in-line flowmeters are designed for use with many caustic or corrosive fluids. These meters feature SS construction and can be mounted in any position.

Variable Area Flow Meters

Variable Area Flow Meters support flow measurement, switching, control, or installation work in liquid, gas, air, water, and process systems. Products in this category span PTFE, PFA, and PCTFE liquid meters, acrylic variable area kits, inline meters with limit switches, easy-view water and oil meters, multi-tube and gas proportioning meters, acrylic air and water meters, oxygen direct-read panel meters, and meters with valves or alarm modules.

Applications include laboratory gas flow, oxygen panels, water and oil flow indication, high-purity chemical lines, corrosive liquid measurement, process sampling, gas blending, purge flow, and local visual flow checks. Products represented in the source data include Omega Engineering and Dwyer Instruments.

Applications include:

  • Read flow visually from a float position
  • Measure compatible liquids, gases, air, water, and oxygen
  • Use acrylic, PTFE, PFA, PCTFE, or panel-mount construction
  • Add valves, limit switches, alarms, or multi-tube assemblies
  • Support laboratory, process, and gas proportioning work
