Types of Flow meters - Vortex Flow Meter, PD, Electromagnetic & More

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.
