Reliability

There are many ABB VA meters still operating after

30. 40 and even 50 years or more. Why?

• ABB’s VA meters are renowned for being the highest

quality available

• They last longer, with millions installed since 1937.

when Fischer & Porter launched their first variable

area flowmeter

• Our trouble-free operation ensures years of accurate

flow measurement

excellent repeatability yields consistent products

Flexibility

ABB’s VA meters are found in almost every application

and industry, with millions sold over the years. Why?

• ABB’s VA meters can be used to measure a wide variety

of liquids, gases and steam

• They require no power and can be used anywhere

• ABB’s VA meters are easily converted to measure

different fluids and capacities

• They are available with alarms, transmitted output

and even HArT communications

Cost effectiveness

Many are discovering that ABB VA meters provide

cost-effective flow measurement for many of their

applications. Why?

• All ABB VA meters are low cost compared to other

flow measurement devices

• In addition they have very low installation costs;

no upstream/downstream straight piping requirements

• Plus their reliability combines for an extremely low

cost of ownership

• Long life expectancy also brings low life-cycle cost

Used for a wide variety of liquids and

gases in most industrial processing

facilities.

Monitors all kind of industrial gas flows, cooling fluids to

protect equipment, sampling systems in laboratories and

flow rates into and out of large tanks.

• easy range change and cleaning-no removal from the

line required

• excellent visibility of flow rate over a 12½ to 1 range

on a linear scale

• Optional one or two bi-stable alarms for contact closure

(or opening) on rising or falling flow

Typical industry applications

• Aeration

• Gas sampling systems, nitrogen generators

• Burner control

• corrosive liquids

• Food and beverage applications

Ideal for many low flow rate applications,

such as purging control lines and

instrument enclosures.

excellent for fluid sampling, liquid specific gravity, level

measurements and other low flow applications.

• simple snap-in tube construction minimizes downtime

for cleaning and replacement

• Internal backcheck to restrict backflow and draining when

tube is removed

• Optional one or two bi-stable alarms for contact closure

(or opening) on rising or falling flow

Typical industry applications

• Aeration

• Gas sampling systems

• Burner control

• Level measurement

• Purging appliications

Suitable for most low flow, high pressure

and corrosive applications in municipal

and industrial settings.

used for gas analyzer systems, various sampling systems,

and situations where glass meter tubes are not appropriate

for safety reasons.

• Measures even dirty and corrosive gases or liquids

• Optional: 4 to 20 mA transmitter output,

minimum ±/or maximum alarms

Typical industry applications

• Water purification

• Gas sampling systems, nitrogen generators

• Burner control

• chemical injection

• Food and beverage applications

The armored VA meter is ideal for the chemical, pharmaceutical

and food industries.

It is exceptionally successful metering aggressive or

opaque fluids, or where glass tube variable area

flowmeters are not appropriate for safety reasons.
