Advantages And Disadvantages Of Using Flow Meters


Flow meters play a crucial role in terms of monitoring and controlling both pressure and rate of flow of liquids as well as gases. Device selection is based mostly on the state of liquid, presence of particles and viscosity. Ultrasonic flow meters are one great example that are based on new technology compared to mechanical and pressure based devices.

These ultrasonic meters are also made for particular applications. They may work on different types of liquids. As long as the speed of sound can pass through a liquid, particle size is bigger than 100um and less than 10% concentration and particles is higher than 100ppm. The device may even work on liquids such as seawater, pure water, wastewater and chemicals. These factors are applicable as well to Doppler meters. The transit time meters work on fluids with clean flow or perhaps, those that have minor particles. Lesser used devices are based on cross correlation which works best on the suspension flow or turbulent gas flow.

Ultrasonic flow meters are regularly used to measure blood flow rate and even pressure in asthma victims. This ability to calculate the flow rate of such wide varieties of fluids is what gives them the edge than pressure as well as mechanical based devices. The absence of movable parts even add to the benefit because of lower maintenance and the ease of use. As expensive as ultrasonic meters may be, the use of it in the long run turns out to be cost efficient than any other devices.

Portability could be achieved when using ultrasonic devices which is a clear benefit in systems that are heavy and bulky can’t be used. Wall mounted devices are a lot better for continuous control and monitoring but, there are handheld models that provide the same results as long as the environment is ideal.

When compared to other types of water meters Australia, ultrasonic flow meters don’t have to be inserted into pipes. Because they are not using pistons and any other movable objects, only the wavelengths, a simple clamp on exterior pipes is enough in getting accurate reading. To put it simply, the device do not corrode saving lots of cost on replacement.

On the other hand, there are pitfalls for making use of variable area meter and one is that there’s not much choice. Cost however is more expensive than traditional meters but this is balanced by making fewer repairs and its low maintenance as well.
