The electromagnetic flowmeter RIF130 using Faraday's law of electromagnetic induction to measure the flow of electrically conducting liquids, according to which a conductor crossing a magnetic field generates a potential oriented perpendicularly to the field itself.
In our case, the conductor is the pipe made of AISI304 stainless steel with flanges made of carbon steel that has two coils installed at the top and in the bottom.
The electric current flowing through the coils generates the magnetic field that causes in the electrodes a difference of potential proportional to the flow.
This potential has very low values, and for having the possibility to measure it, the inside of the measuring tube is electrically insulated. Accordingly the process liquid never comes into contact with the material of the tube or with the material of the flanges.
The flowrate converter generates the current supplying the coil, it acquires the potential difference by the electrodes, processes the signal to calculate the flow rate and manages the communication with the outside.
- Good accuracy
- Measuring device fixed
- Suitable for dirty liquids and abrasavi
- No limitation on the viscosity of the fluid
- Possibility of bidirectional measures
- High labor camp
- Pressure drop void
The main applications are made in the following sectors: chemical industry, energy sector (generation and distribution), mining, water treatment, paper industry, pharmaceutical industry, food industry and environmental protection.
The measurement is independent of density, viscosity, temperature, pressure and conductivity (> 5μS/cm) of the fluid.
The measurement tool must not esserepercorso from fluids carrying solid bodies of high dimension which can not be considered solids in suspension.
They are assentile load losses and are necessary rectilinear reduced upstream (3Diametri) and downstream (2 diameters) of the instrument.
