Electromagnetic Flowmeter
Electromagnetic Flowmeter
Electromagnetic Magnetic Flowmeter - A conductive process fluid is run through a magnetic field. As it creates an electric charge through its interaction with the field, the charge is measured to find the speed of the flow.

George Fischer Signet : 2551 Magmeter Flow Sensor
George Fischer Signet : 2551 Magmeter Flow Sensor

The Signet 2551 Magmeter is an insertion style magnetic flow sensor that features no moving parts. The patented* sensor design is available in corrosion-resistant materials to provide long-term reliability with minimal maintenance costs. Material options include PP with stainless steel, PVDF with stainless steel, PVDF with Hastelloy-C, or PVDF with Titanium. Utilizing the comprehensive line of Signet installation fittings, sensor alignment and insertion depth is automatic. These versatile, simple-to-install sensors deliver accurate flow measurement over a wide dynamic range in pipe sizes ranging from DN15 to DN300 (0.5 to 12 inches), satisfying the requirements of many diverse applications.

Signet 2551 Magmeters offer many output options of frequency/digital (S3L), 4 to 20 mA or relays which are available on both the blind and display versions. The frequency or digital (S3L) sensor output can be used with Signet’s extensive line of flow instruments while the 4 to 20mA output can be used for a direct input to PLCs, chart recorders, etc. Both the 4 to 20 mA output and digital (S3L) sensor interface is available for long distance signal transmission of up to 1,000 ft. An additional benefit is the empty pipe detection which features a zero flow output when the sensors are not completely wetted. Also, the frequency output is bi-directional while the 4 to 20mA output can be set for uni- or bi-directional flow using the display or the RS232 set-up tool which connects to PCs for programming capabilities.

More about Electromagnetic Flowmeters
The operating principle of magnetic flowmeters is based upon Faraday's Law of electromagnetic induction,
" It states that a voltage will be induced in a conductor moving through a magnetic field."
Faraday's Law :
E=kBDV Where
E = Induced Voltage,
B = Strength of the magentic field,
D = Conductor Width,
V = Velocity of the conductor.
The magnitude of the induced voltage E is directly proportional to the velocity of the conductor V, conductor width D, and the strength of the magnetic field B. Magnetic field coils placed on opposite sides of the pipe generate a magnetic field. As the conductive process liquid moves through the field with average velocity V, electrodes sense the induced voltage. The width of the conductor is represented by the distance between electrodes. An insulating liner prevents the signal from shorting to the pipe wall. The only variable in this application of Faraday's law is the velocity of the conductive liquid V because field strength is controlled constant and electrode spacing is fixed. Therefore, the output voltage E is directly proportional to liquid velocity, resulting in the linear output of a magnetic resulting in the linear output of a magnetic flowmeter

Magnetic Flowmeters
Magnetic flowmeters are based on Faraday's Law of Magnetic Induction. In a magnetic flowmeter, the liquid acts as a conductor as it flows through the pipe. This induces a voltage which is proportional to the average flow velocity - the faster the flow rate, the higher the voltage. This voltage is picked up by sensing electrodes mounted in the meter tube and sent to the transmitter which takes the voltage and calculates the flow rate based on the cross sectional area of the meter tube.

Where to use

  • High percentage of solids
    Sludges, slurries, minerals, paper, sewage - flows with high levels of solids which cannot be measured other types of meters.
  • Obstructionless measurement
    Nothing projects into the flow stream, no head loss, no parts to maintain.
  • Very corrosive liquids
    Acids, caustics and corrosive chemical additives are isolated from the meter by inert linings and electrodes.
  • Conductive Liquids
    Liquids where conductivity is at sufficient levels to induce measurable voltage
