Variable area flow metr overview
A wide variety of flow-meters are available
in the market. Although the Variable Area (VA) flow-meters may not be the most
versatile equipment in their category due to the fact that they have numerous
limitations on their functionality, they're still hugely popular in the markets
all over the world. Arguably, the main reason for rotameter flow-meters to be
favored by many customers is their low cost.
The cost of a variable area rotameter
flow-meter is generally much lower than other types of flow-meters making them
an ideal choice for those users who need effective and inexpensive solutions.
While you're looking for a flow-meter, if cost is your main consideration, the rotameter
type is your best option.
Metal Tube Rotameter flow meter equivalent
HH50 series metal tube variable area flow meter is an
economical equivalent of many top brands VA flow meters, we can replace below
brands at very low price cost of below brands:
Rotameter, FLOW INDICATOR, TYPE METAL TUBE ROTAMETER, H250
KROHNE cheap equivalents
ABB Variable Area Flowmeters (Rotameters) inexpensive replacements
Brooks instruments , Armoured Metal Tube Flow Meter low cost equivalents

replacements.
Types of rotameter Flow-Meters.
Even among the variable area flow meters,
you get variations in cost. This is based on the material used for the meter's
construction. The cheapest rotameter meters are made of plastic, which may be
used for fluids having low temperatures and low to normal pressures. Glass made
VA meters may be used for average temperatures and pressures, while for high
temperature fluids with high pressures, metal tube varaiblea area flow meter/rotameter should be utilized,
which are the costliest.
There are different types of rotameter
flow-meters for different applications. If you're looking only to determine
whether there's any flow of fluid or not, without any alarm, there are rotameters flow meters for this task. In some cases, you might need a VA meter to measure the
flow. You can buy a VA meter, which gives the flow reading and has to be read
manually or you may go for a variablea area flow meter transmitter fitted VA meter with analog 4-20mA output.
Whatever may be your requirement, you can find a suitable Rotameter flowmeter
for it at an economical cost.
Utility of VA Flow-Meters. While the rotameter flowmeters are mostly used in processing industry, they also find wide variety
of other uses such as in laboratory testing and research works. They're
utilized for in these fields for air and gas flow measurements in low flow rate measurement applications. The VA meters are typically best for all fields where visual
measurements are adequate without much precision. They are sometimes also used
to keep a check on the functioning of other flow meters or as a secondary
measurement mechanism. Almost all OEM applications continue to use the metal-tube rotameter flow
meters including those made with plastic.
Latest Technological Developments in VA
Flow-Meters
The development of transmitter output for
variable area flowmeter has been one of the most important stepping stones in
the applications of these pocket friendly meters. Currently it can be with
digital display ,24V DC or 220V AC power supply , 4-20mA output or RS485 RTU
communication . Besides, the Highway Admissible Remote Transducer (or HART)
protocol is now available in some of the new models of VA flow meters, which
further enhances the utility of these equipment. They can be used as more than
just a visual indicator as it's possible to control and record readings remotely.
In a word, metallic tube rotameter with transmitters are widely used.
Another variety of variable area flow
meters, known as the purge-meters has recently been developed that can handle
different low flow applications. Float designs and metal tube construction
materials are other research areas for flow meters. In the overall scenario,
the VA flow meters continue to be used in almost all fields wherever precise
flow measurements are not mandatory.
