A flow meter
refers to a device that measures the mass or volume of a gas or liquid. Just as
the name flow meter suggests, it measures the flow of either gas or liquid.
Other names for flow meters include flow indicator, flow gauge, and liquid
meter. Flow meters are used in different industries, including the
pharmaceutical/ chemical industry, food and beverage industry, water companies,
and gas and oil plants. Different types of flow meters apply to these various
industries. This article discusses chemical flowmeters.
They refer to flow
meters that measure both corrosive and non-corrosive gas and liquid passing
through them. They can measure various substances, including solvents, acids,
detergents, pesticides, and many more. Chemical flow meters are common in
industries like petrochemical plants and refineries. In such industries, they
play a vital role in the manufacturing process since they help to enhance
Different types of
chemical measurement-Variable area rotameter/ magnetic flow meter
industries use magnetic flow meters to facilitate the aggressive measurement of
chemicals. You can use magnetic flow meters
to measure corrosive chemicals like
hydrochloric acid, sulphuric acid, caustic soda, and brine. However, only
magnetic flowmeters that have suitable electrodes and liners are efficient in
measuring such corrosive liquids. Additionally, you can also measure the
aggressive chemicals/fluids using digital rotameters that are lined with PTFE
Low corrosive, low
viscous and clean liquid measurement -Turbine flow meters (TUF)
These are flow
meters that measure liquids that are clean, less viscous, and less corrosive.
Such fluids include solvents, solutions, ethanol, diesel, and clean water. Turbine flow meters
are less expensive and usually have chemical flow sensors
that have a compact design. These flow meters are volumetric, meaning that they
can measure liquids passing through them either indirectly or directly. Some of
the advantages of using turbine flow meters are that they have high accuracy,
can measure high pressure, and have a large measuring range.
Low flow rate flow
meter -Rotameter or micro type oval gear flow meter
measures the flow rate of a gas or a liquid. It comprises a measuring scale,
float, and a tube. A low flow rate rotameter
detects a minimum/low flow rate in
a liquid/gas. In this category of rotameters, we supply a rotameter known as
the metal tube. The tube in the metal tube is usually tapered and has
indicators. The function of the indicator is to display the measuring results
after measuring. These tubes also have pulse output/4-20Ma transmitters, which
facilitates control. Rotameters are cost-effective since they are easy to
construct. Therefore, using them helps to save costs. They also have a small
design hence portable.
LC-M Series Micro oval Gear flow meter can detect ultra mini
chemical flow, It is a kind of positive displacement flow meter for precise volume
flow measurement of mini or low chemical flow liquid, the liquid include
chemical, sealant, toluene, glue, detergents, gelectrolyte, ethylene, additive,etc
chemical flow meters-Coriolis flow meter & oval gear flow meter
Both the oval gear
flow meter and the Coriolis flowmeter measure fluids that have high viscosity.
Such fluids include glue, resin, asphalt, and molasses. Oval gear flow meters
have two oval gears which they use to trap the fluids. On the other hand, a Coriolis
flowmeter has a tube and a vibrator for fluids measurement purposes. The flow
sensors present in these two flow meters have a rugged design and are bulky
too. The flow meters have different protocols and outputs, which helps to
control processes in the factory facility.
