Variable speed drives, soft starters and irrigation meters

Our society is made by the combination of various sectors like residential sector, commercial sector and so on. One such sector is agricultural sector. Irrigation system plays an integral role in establishing and maintaining our agricultural sectors. Basically, irrigation system can be defined as the process in which water is supplied from some artificial source to the crops or to landscapes. There are various types of irrigations systems but on a general level we can divide this system into types. One type of irrigation system is in which water is sprayed through various emitters and is known as low flow irrigation system. Then there is another type of irrigation system in which water is quite sufficiently provided all over the crops and is known as high flow irrigation system. Obviously, this supply and consumption of water must be measured properly to keep the check on the irrigation efficiency. This check is maintained by various technological devices that have been introduced to us; thanks to science. In this article, we will be discussing about variable speed drives, soft starters and irrigation meters. 

Flow measurement: 

Maintaining the agricultural sector is not an easy task. The functioning of this whole irrigation system must be properly controlled. You cannot just provide as much water as you want to the crops rather the supply of water must be properly measured. Irrigation efficiency is maintained when the water supplied perfectly matches with the water consumed by the crops. This irrigation efficiency can only be kept in check by measuring the flow of water. Basically, there is this process of flow measurement in which the flow of any kind of gas or liquid is measured by the use of various devices. One such device which is used to measure the flow of water for the irrigation systems is known as irrigation meter.  

Irrigation meter: 

In simplest words, irrigation meter can be defined as the kind of a meter which is used to measure the amount of water that is supplied to the crops, landscapes or any other huge land. Even though this meter does not change the consumption of the crops or the land but it does change the water bill which is separated from the water coming from the sewer pipes. It won’t be an exaggeration to say that irrigation meters are the essential requirement if you want the proper functioning of irrigation system. 

Soft starters: 

As we have already mentioned that there are various devices which are used for the proper functioning of irrigation system and ultimately the agricultural sector so one such device is known as soft starter. Soft starter is the device that is used to regulate or control the flow of electricity current while it is being started. The flow of current might come with the excess load which can result in damaging the whole meter system so this soft starter is used to regulate the current’s movement. The name of this device clearly explains its purpose. 

Variable speed drives: 

Variable speed drive is the kind of a device that is used to control or regulate the varied frequencies of electric current, magnetic flux or impedance. There are many alternative terms which are used for variable speed drives like variable voltage and frequency drive, adjustable frequency drive or variable frequency drive. Another noteworthy point in here is that soft starters and variable speed drives are not the same thing rather soft starters are used while initiating the process. However, variable speed drives are used throughout the functioning of the system.


Irrigation system plays a major role in the maintenance of the agricultural sector. Irrigation system is much more than merely watering the crops and cutting them once they are ripped rather it involves various other necessary steps as well; one of which is to keep a check on the irrigation efficiency. This check is provided by measuring the flow of water and regulating its movement. The devices like irrigation meters, variable speed drives and soft starters play an essential role in maintaining the irrigation system. “Macquarie valley irrigation meters” offers the best quality of irrigation meters, variable speed drives as well as soft starters.
