TR-DTI series electromagnetic flow meters follow the Faraday law of electromagnetic induction.They can be used to accurately measure the flow rate of liquids which are electrical conducting, caustic, and mixed with liquids and solids.They are widely used throughout industries of petroleum, chemical engineering,pharmacology,paper making,electric power, environmental protection and so forth.
Structure:
TR-DTI series electromagnetic flow meters are made up of sensor and transducer,together with LCD screen,current and pulse output,alarm signal and RS-485 communication.
Operating principle:
Faraday’s laws of induction from the basis for the electromagnetic flow meters.It states that a voltage is induced in a conductor as it moves through a magnetic filed.
This principle is applied to a conductive fluid which flows through a magnetic field generated perpendicular to the flow direction(see Schematic).
The voltage induced in the fluid is measured at two electrodes,installed diametrically opposed.This signal voltage UE is proportional to the magnetic induction B, the electrode spacing D are constants,a proportionality exists between the signal voltage UE and the average flow velocity v. The equation for the volume flow shows that the signal voltage UE is linear and proportional to the volume flow rate. The induced signal voltage is processed in the converter into scaled, analog and digital signals.
