Why Does Electromagnetic Flowmeter Matter in Flow Measurement?
Flow measurement is paramount in liquid transfer through pipes. Accurate measurement tools like electromagnetic flowmeter offers vital advantages such as quality control, safety, and cost-effective operations. The parameter ensures the right liquid going through the right liquid at right velocity. This certainty offers better quality in operations. Besides, having a good flowmeter is essential to make the processes safer and giving a healthy environment for those who work in the industry.
How does electromagnetic flow meter work?
Diverse substances are transferred through pipes including acid, alkalis, paints, pastes, water, wastewater, etc. And electromagnetic flowmeter makes the flow measurement easy and error free. The basic physics behind the principle of electromagnetic flow meter goes back to Michael Faraday, who invented that electrical current can be generated with a magnetic field.
Let’s see how electromagnetic flowmeter works. In the electromagnetic measuring principle, the flowing medium is the moving conductor. The voltage induced is proportional to the flow velocity and is supplied to the amplifier by means of two measuring electrodes. The flow volume is calculated by means of the pipe cross-sectional area. The DC magnetic field is created through a switched direct current of alternating polarity.
Electromagnetic flowmeter type PEM-1000
Electromagnetic flowmeter type PEM-1000 is manufactured by one of the leading providers of high-quality process solutions. With its high accuracy and wide application, PEM-1000 is used by several industries for flow measurement. The flowmeter consists of a transmitter and a sensor.
Two types of PEM-1000 are available based on where the sensor is located. One is compact version, PEM-1000ALW in which transmitter and sensor form a mechanical unit. The other PEM-1000NW known as remote version, in which sensor is mounted separate from the transmitter.
Advantages
Using an electromagnetic flowmeter has several benefits. It is manufactured in different sizes to measure flow in pipes of any size. Unlike other flowmeters, there is no obstruction to flow that may cause pressure drops, thus the most accurate result will be derived. Besides, the output is unaffected by changes is characteristics of liquids such as viscosity, pressure and temperature.
When it comes to PEM-100 series of electromagnetic flowmeters, there are some added benefits. Firstly, it is quite easy and simple to assemble. As said earlier, it has two versions. However, depending on the process you can easily change from compact to remote version in less time. The transmitter is made of high-quality materials, and it help you use it for every flow analysis application. And to maintain the quality and durability, robust and resistant cover of sensor and transmitter is offered.
