Digital irrigation flow meters mainly are ultrasonic flow meters and magnetic flow meters at present. Digital flow meters have been widely used for agriculture and turf, and typical application including the following:
- Agriculture fertigation
- Golf Watering
- Pivot irrigation
- Irrigation sprinkler
Water has been one of the most precious resources in the world,and more and more places are facing the problem of water lacking.Most of countries and areas have charged fees for water consumption.Agricultural irrigation always requires plenty of water for crops.Thus, a precise irrigation flow meter for DN50-DN100mm is essential to measure how much water has been used. Meanwhile, as agricultural irrigation has its unique application:irrigation flow meters may be carried for different of applications in different farm,so its weight shouldn't be too heavy.
In the past, mechanical water meters or flow meters were used for irrigation flow metering and mainly include water meters,liquid turbine flow meters,etc. The flowmeters have moving parts and have many disadvantages:pressure loss, shorter life,accuracy reduced after using, bigger weight,etc. Thus,proper irrigation flow meters are required to avoid those problem: they are ultrasonic flow meter and electromagnetic flow meter.
Even though use the two kinds of digital irrigation flow meters, there are still several different solutions.
1.Solar Powered Clamp On Ultrasonic Flowmeter
Clamp on ultrasonic flow meter dosen't require to cut pipe and easy to install&operate. But clamp on flowmeter may cost power much sharply than inline&insertion type. So built-in battery is not good solution for several days flow measurement. But if you just require a day measurement,our portable flow meter with battery is a good choice.Other a storage cell is required.If just want the flowmeter to work for several days,e.g. a week, a storage cell should be enough. But if want to work for more days,solar power is required.
2.Battery Power Inline or Insertion Ultrasonic Flowmeter
As our ultrasonic flow meter is lower power consumption,thus inline or insertion flow meter can be powered by built-in 3.6V battery. Such solution can make irrigation flow meter work for 4-6 years,even longer,so the solution doesn't require external storage cell or solar panel.
If irrigation pipe size is below DN65mm, inline ultrasonic water meter is a better solution. If over DN65mm,insertion and inline type are all right. You can select it as your requirement.
3.Battery Power Ultra-light Ultrasonic Flowmeter
In order to reduce the weight of irrigation flow meter, we specially designed ultra-light insertion flow meters for irrigation. It has a compact body and very light weight.It is also powered by built-in 3.6V battery and can work for 4-6 years. Its main size is DN80mm and DN100mm. And its price is much cheaper than other types. It is an ideal type for your irrigation flow measurement.
4.Battery Power Inline Magnetic Flowmeter
As the main competitor of ultrasonic water meter,battery power magnetic flow meters are also often selected as irrigation flow meters.But its price is much higher than ultrasonic water meters,meanwhile, its weight may be bigger than ultrasonic type.
We can make the two types flow meters and provide them as your requirement. But we recommend ultrasonic type as first choice.
5.Plastic Inline Turbine Flow Meter
This solution has moving parts and not recommended.But there are still many suppliers to provide such solution. End users are not familiar with flow technologies,but as distributors or manufacturers, the solution shouldn't be recommended unless requirement.
Anyway, in order for such requirement,we also provide plastic type turbine flow meters. Plastic body can reduce the weight. The turbine flowmeter uses impeller rotation to 'sense" water flow,thus its working doesn't require external power.But if require signal output, its converter will require,but in regard that it is just signal, a battery power should be enough. If battery power costs up, user can replace a new one.
6.Woltman Water Meters
Woltman water meters have ever been the main selling type in irrigation application. Though its technology is backward, it is easy to manufacture,thus they have been sold and installed in many countries and areas. It also uses rotation impeller to calculate water flow rate. However, it is facing the problem of eliminating.
7.Paddle wheel Flow Sensor Meter
Our paddle wheel flow meter sensor is not heavy and has pulse output. Meanwhile, its price is not higher. Thus, paddle flow meter sensor is often selected as irrigation flow sensor. We have developed related digital flow controller to make it as digital irrigation flow meter.
Landscaping and Turf Irrigation Flow Meter Sensor
Unlike agriculture irrigation, turf and landscaping irrigation may use smaller size pipe.e.g. below DN40mm. For such application,we can provide small size digital water flow meter or water flow sensor,which mainly includes
- Hall effect flow sensors
- Plastic variable area flow meter
- Turbine flow sensors
- Ultrasonic flow sensor
- Other customizing flow devices
In a word, ultrasonic flow meter and magnetic flow meter should be the main irrigation flow meters at present. When you need to purchase flow meters for irrigation watering,it is better to select either as your first choice.
You may easily find the result: yes, ultrasonic flow meters and magnetic flow meters are the better solution for digital irrigation flow metering. Comparing with mechanical irrigation flow meters, they have very good advantages as below:
- Higher accuracy
- Lower velocity sensitivity
- Longer using life obviously reduces your average investigation
- Powerful function to record positive/negative/NET flow rate
- Stronger communication ability: batch controller, data logger, GPRS/GSM wireless communication, Modbus for network,etc
- Clamp on ultrasonic flow meters don't need to cut pipe and lightweight to carry for different test points. Reduce your comprehensive investigation.
- Low cost clamp on flow meter solution from ABEST only. With cutting edge technology,we have reduced the price of clamp on flowmeter to a very low point that will give you a big surprise.
