There are many types of flowmeters
and flowmeter-related equipment available on the india marketplace. These include, but are not
limited to, industrial and sanitary turbines, variable area flowmeters, flow
transmitters, flow alarms, flow indicators, specialist medical gas flowmeters,
multipulse positive displacement flowmeters, batch meters, insertion meters,
electromagnetic flowmeters, Watermeter flowmeter and irrigation meters.
Vortex Flowmeter (VSF) is a kind of the vibration meters. It simple configuration, and
install conveniently. It can measure and control various liquid (e.g.: water,
oil, petroleum, alcohol, acid, alkali and different chemical fluids) gas (e.g.:
air, oxygen, N2, natural gas, coal gas), and steam (e.g.: saturation steam,
overheated water vapor).
Thermal
sensor consists of two sensing elements - a velocity sensor and a temperature
sensor that automatically corrects for changes in gas temperature(figure1). The
transducer electronics heats the velocity sensor to a constant temperature
differential above the gas temperature and measures the cooling effect of the
gas flow.
Addmas
balanced PD Flowmeter is kinds of energy saving and have several function
apertures, which could make flow area balanced into ideal current, leading a
innovation to global measurement technology. it has already been widely used
among petroleum, chemicals, metallurgy, electricity and natural gas.
Flow meters are devices used to gauge gas or fluid flowing through it. They're used in a variety of applications where measuring flow is needed to check for leaks, control pressure and even prevent asthma attacks in asthma patients.
The devices are categorized based on
driving systems with mechanical, ultrasonic, pressure, electromagnetic Flowmeter being
a few examples. Let's look at how they work.
Mechanical flow meters
These are traditional devices which
still continue to be used. Basic types use turbines or wheels inserted into
pipes to measure velocity and calculate volumetric flow by using the area on
the pipes they're located.
Mechanical flow meters can be of
various types with common examples being piston meters - which use rotating
pistons -, gear meters - which use a pair or more than two gears rotating at
right angles - and single jet meters - which use impellers to increase and
decrease liquid flow.
