Variable Area Flow Meters
Economical machined cast acrylic block construction makes these meters great for OEM use. Optional inlet metering valve available
The Bailey-Fischer & Porter PURGEMASTER® 5 inch scale purgemeters are low capacity variable-area flowmeters for both liquid and gas with a nominal accuracy ±2% of full scale. The meter features a corrosion resistant stainless steel body and is available with or without a built in control valve. Other features include a quick,...
The PURGEMASTER® 3 inch scale purgemeters are low cost variable-area flowmeters for low capacities of both liquid and gas with a nominal accuracy ±10% of full scale. The meter features an optional built in control valve, a corrosion resistant stainless steel body, quick, easy snap-in tube constructions and a safety tested operator...
The armored variable area flowmeter offers new possibilities for metering small flowrates of liquids and gases.The instrument is particularly well suited for metering cloudy, opaque or aggressive fluids.
The ABBSeries 10A2235A Ratosight flow rate indicator is a rugged, low cost, glass tube, variable area flowmeter that provides stable and reliable operation while measuring liquid or gas flow rates. This indicator can be supplied with Ratoalarm extension (Series 10A2235-OA) for alarm actuation. The alarm unit can house one or two vibration-proof...
The Purgemaster Purge Meters are low capacity variable area flowmeters for both liquid and gas with an excellent selection of material and scale lengths in a single product family design. They provide optimum flexibility with minimum component proliferation. The meter features a corrosion resistant, high strength stainless steel body, quick,...
VA Master FAM540 variable area flowmeters are installed vertically in a pipeline. The flow must travel in an upward direction. Keep the meter as far as possible from pipeline vibrations and powerful magnetic fields. The pipeline should be the same size as the connection size of the flowmeter. Inlet and outlet straight pipe length are not...
Acrylic block construction with direct reading scales have white screen printed backs to enhance scale readability. Connections are in-line for easy installation.
Available with NPT or flange connections, vertical or horizontal, this 127 mm scale glass tube meter offer value and versatility in 304 stainless case construction.
Side plate style meters with 75 mm or 150 mm borosilicate glass tube and 316L stainless steel or brass connections. Valves optional. Also available with PVC ends and Hastelloy® C-276 construction for greater chemical resistance
A real value in general purpose rotameters. Vertical connections are from 3/8 NPT to 2 NPT
Our variable-area flowmeters are designed for liquid or gas applications where rotameters often fall short. These models have large dials with bold markings and characters that are easy to read from a distance. They also handle high line pressures and can be mounted in any orientation.
Like rotameters, they are mounted directly in...
Our fixed-orifice flowmeters are designed for low flow applications, from 0-2 to 0-40 GPH. Like our variable-area flowmeters they are built from solids blocks of metal making them a favorite for high line pressure applications, to 3000 psi. You will find many in hydraulic and pneumatic systems.
Though rugged, they maintain the...
The Rate-Master® flowmeter line of direct reading precision flowmeters incorporates many unique user features at moderate cost. These low cost flowmeters are ideal for general use.
Easy to read design — The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the...
The Visi–Float® flowmeter bodies are cut and precision machined from solid, clear acrylic plastic blocks. This construction not only produces a handsome finished product, but permits complete visual inspection. As a result, the Visi-Float® flowmeters are especially popular for medical and laboratory equipment applications.
