So, what exactly is an Electromagnetic Flowmeter?
Well, it’s a measuring instrument used to determine the flow rate of fluids in pipes, based on the electromagnetic properties of the fluid flowing through them. This type of flowmeter is particularly useful for measuring water flow in irrigation and domestic consumption pipelines.
DIN flange connection
Regarding the DIN flange connection, we must say that it is one of the most commonly used connections in the industry. Additionally, it is important to mention that this connection is standard and commonly used in different types of pipelines. Furthermore, it allows for secure and hermetic fastening of the flowmeter.
Stainless steel tube and flange
As for the tube of the electromagnetic flowmeter, it is made of stainless steel, which guarantees high resistance to corrosion and durability. The stainless steel flange also provides excellent resistance and durability.
The PTFE (polytetrafluoroethylene) lining is a highly resistant material to corrosion, as well as to abrasion and extreme temperatures. It is used specifically to coat the interior of the flowmeter tube, providing a smooth and non-sticky surface for the fluid to pass through.
Stainless steel electrodes
Stainless steel electrodes are responsible for measuring variations in the electromagnetic field generated by the fluid flowing through the tube. These electrodes, in particular, being in direct contact with the fluid, must be resistant to corrosion and incrustations.
220V AC power supply
Finally, the electromagnetic flowmeter operates with a 220V AC electrical supply, making it compatible with most domestic and industrial electrical installations.
Precision and outputs
These flow meters offer a precision of 0.5%, ensuring reliable and accurate measurements at all times.
4/20mA and pulse outputs
Electromagnetic flowmeters also have two types of outputs: 4/20mA and pulse. The 4/20mA output is an analog signal that allows for communication with other devices such as controllers and monitoring systems. On the other hand, the pulse output is a digital signal that can also be used to count the volume of fluid passing through the flowmeter in a specified period of time. Both outputs offer different ways of processing and using flowmeter measurement information.
Applications of electromagnetic flowmeters
Measurement of flow in irrigation pipelines
For example, electromagnetic flowmeters are commonly used in measuring the flow of water in irrigation pipelines, allowing for efficient control and proper distribution of water in crops.
Measurement of flow in domestic consumption
It is also very useful for measuring the flow of water in domestic consumption facilities, providing valuable information for the management and control of water consumption in households.
The electromagnetic flowmeter is a precise and versatile measuring instrument that is used in various applications, such as controlling water flow in irrigation pipelines and domestic consumption. Its robust construction and corrosion-resistant components guarantee a long lifespan and accurate measurements at all times.
