Paddlewheel flowmeters are famous in the flow measurement industry. They are easy to install and maintain, that is why they are popular. Always make sure to locate paddlewheel meters well in the existing pipe. They have one moving part, and this makes them more durable compared to other meters.
Paddlewheel flowmeters are essential. And you should always know several things before you buy them. Paddlewheel flowmeters are necessary for;
· rural areas for irrigation
· wastewater facilities
· and many other applications
Also, if the liquid flow is turbulent, the paddlewheel sensor can be used for thick fluids. Paddlewheel flowmeters are the best meters for many applications. Always make sure of the following factors before you buy a paddlewheel flow meter.
Things to Consider Before Buying A Paddlewheel Flow Meter
The Fluid Media
When choosing a paddlewheel sensor, always make sure to understand the process media fluid. Ask yourself whether it is a gas, a liquid, or steam measuring. These meters measure wastewater, clean, or even corrosive.
Also, before you buy a meter, make sure you understand its chemical properties. If you fail to consider this, you will get some extra maintenance or replacement costs.
The Accuracy Levels
Accuracy is essential in measuring the flow of liquids. Paddlewheel flowmeters should be accurate for better measurements. Make sure you check the accuracy levels before buying it. Also, make sure you know how accurate your measurements have to be for the best results.
The best meter has to be plus or minus 0.01 percent of the full scale. But you will have to pay more if you want this kind of accuracy. If you measure the flow of liquids in industries like;
· biochemical
· medicine
· or food and beverages,
your paddlewheel meter should be more accurate. In other industries, the flow is less critical, so the accuracy levels have to be good, not precise.
The Repeatability
When buying a paddlewheel meter, always make sure to ask the seller about its repeatability. It is as important as its accuracy. Repeatability means the consistency of the meter during the flow measurement. Most meters are calibrated to channels flowing certain, and so the accuracy can drop. Knowing about the repeatability of the paddlewheel meter will help you to compare accuracy in different meters. Make sure you know the repeatability of the meter before buying it.
The Installation Process
Before you buy paddlewheel flow meters, make sure to understand their installation. The installation process is different in every meter. So you should always seek help from the seller. Paddlewheel meters will require a straight pipe and run upstream for a stable flow profile. If you do not follow the instructions given to you by the manufacturer, your accuracy levels will be lower.
Also, if you put the meter too close to the pumps, valves, or other instruments, it will lead to unstable flow. This will then lead to maintenance problems. Always make sure you understand the installation process of a paddlewheel flow meter before you buy it.
Maintenance Cost
Ask the seller about the maintenance needed of the paddlewheel flow meter before buying. Make sure you know how often you need to clean and inspect the meter. A paddlewheel meter has one moving part. And so this makes the maintenance cost lower compared to other meters.
The Durability of the Meter
Before you buy a paddlewheel sensor, make sure you know its life cycle. Some meters last up to twenty-five years and do not require maintenance. Other meters last for only two years. The durability of a meter depends on the application. When selecting a paddlewheel meter, always make sure it is long-lasting. Doing this will save some money.
The Operating Temperature and Pressure
Paddlewheel meters may be affected by fluid temperature and pressure. If this affects its accuracy, you will need to buy a meter that has built-in temperature replacement. Buy a meter that can withstand high temperatures and pressure for better accuracy levels.
Some meters work well in regular flow rates while others in high turndown applications. Paddlewheel flowmeters have one moving part. And so they are suitable for high temperature and pressure fluids.
Battery or AC Operated
Before you buy a paddlewheel flowmeter, make sure to know whether or not they are advanced. Most paddlewheel meters today use batteries, and this removes the electrical connections. The batteries last for a minimum of one year because of technology. If you replace these batteries, you will not destroy the meter.
Paddlewheel flowmeters the best capabilities like;
· batch process control
· analog output signals
· and remote readouts
The meters use a power source supplied by AC/DC transformer. Also, make sure to understand the flexibility of a paddlewheel meter before buying it.
Conclusion
Paddlewheel flow meters are always the best if you want highly accurate measurements. They are also easy to maintain and install and measure flow in either direction. Before you buy a paddlewheel flow meter, make sure you research more about it. The above considerations will help you buy a suitable meter.
