Suited Applications and Usage of Water Flow Meter


A water flow meter is a tool used to gauge the flow rate or the amount of water used in domestic and commercial spaces. The water is fed to homes and offices through water supply orders. Water meters are used in all places, such as the source, to gauge the setup’s flow rate. Below are some water flow meter suited applications.

The ultrasonic water flow meter is one of the most used versions of water meters. It uses ultrasound to gauge the flow of water. There is a transit-time design of an ultrasonic meter that signals the downstream and another on the upstream.
From there, the flow meter com[ares the moving time for both signals to identify the flow speed. Once it has the readings, it uses them to get the volumetric rate of flow.
If you wish to gauge the energy and heat, you can use the difference between hot and cold legs. There is a wide range of applications for this meter in the industry. Some of them include the gauging of flows in huge tubes. IT is also used to measure flow in boiler feed water.

Electromagnetic Meters

Electromagnetic Meters
These meters operate by the use of a magnetic field based on Faraday’s law. The liquid moving through the magnetic field forms a charge. That means that when the liquid moves faster, there is an increase in voltage created equal to water motion.
Afterward, the water flow meter produces the voltage into the flow rate. One of the drawbacks of this meter is that you cannot use it for custody shift since it does not give accurate results. The water meter doesn’t operate on pure water since there are no ions to gauge.
Before choosing the right type of this meter, consider some factors. Some of these factors include chemical compatibility and flow speed. That will help you know the type of application that you desire.
You have to put in mind if the meter can react with the water used in the setup or if the dirt in the water could lead to blockages if you use a mechanical fastener with an intrusive link with the fluid. The last detail that has to be checked before carrying home your meter is the fluid’s flow velocity. Factor all this info onto the heart before you pick the best water flow meter for your application.
Pure water can be used with almost any type of meter. That is because water does not need special liner materials as it is docile with all popular liner material on flow meters. One liner that fits pure water and works optimally is hard rubber or polyurethane. If the setup used is likely to rust or process water needed for other things, you can look for a different liner to meet your needs.

Turbine flow meters

Turbine Flow meters
Do you need a cheap and accurate gauging meter that works with almost all water sources? It is time to get a turbine flow meter. That is due to the low price it is affordable to all, and hence it is the most popular meter in use.
A turbine gets readings of the water flow rate in a pipe with a spinning turbine or piston’s help. The meter is made in the shunt, propeller, or paddlewheel model. As the water moves in the pipe, it pushes against the turbine’s propellers, causing a rotational spin.
The turbine is fitted with magnets on the blades of the turbines. As the blades spin, magnets spin, causing a change in the magnetic field. The magnetic field is detected as an electric charge by the sensors on the flow meter.
Charge detected pro-rata to the rate of flow. The flow rate is pro-rate to the speed of the spin in the blades hence an accurate gauge.
Turbine meters have a shortfall, such as clogs when used in chunky or dirty water. This shortfall causes the meter to be hard to keep in process water as it raises maintenance costs. It, therefore, is preferred for clean water use alone.
But due to its cheap cost and wide availability, it is used for most water meters.

Vortex Water flow meter

vortex flow meter
A vortex flowmeter works by the Von Kaman effect. The law states that if a bluff body interacts with a fluid, it leads to vortices pro-rata to flow rate. Vortices are swirls that form as fluid moves past an obstacle.
In this type of meter, a sensor tab flexes from side to side as each vortex flows past. The flex causes a frequency pro-rata to the rate of flow. Multivariable vortex meters gauge up to five variables at once. They can gauge flow rate, density, stress, heat, and mass flow. Insertion meters work well with big pipes as they can be fixed by tapping with a refractor.
The meters are used for district heating. District heating takes heat from one place to residential or commercial spaces, such as ass space heating and water heating. The manager at the facilities gauges the steam using vortex meters.
Since a vortex meter can fit any pipe size, it is used in low steam measurement that would need fitting new pipes to use other flow meters. The fanged vortex can fit ½ of an inlet section but have good precision.
Breweries and food plants need to measure many factors such as heat, stress, and flow, which are managed with a single meter rather than buying each tool for every aspect. As you can see, vortex meters are very versatile and needed in many firms. As long as the firm uses water or water solutions or even steam, there is no place a vortex meter can’t be used.

Final Thoughts

Most water flow meter types are used for handling both hot water and cold water, dirty water, clean water, and slurries. The water flow meter has so many uses, as you have analyzed in the above list. The most common way of water flow gauging is velocity and displacement. Each meter used has merits and cons.
