Electromagnetic Flowmeter advantage
Good stability, precision 0.5, repeatability of 0.25%, measurement accuracy, no pressure drop, no moving or protruding parts, wear resistance, corrosion resistance. Can be installed in any piping system with low conductivity measurement of liquid, slurry and mud ideal instrument.
Electromagnetic Flowmeter
Intelligent electromagnetic flowmeter is based on the principle of electromagnetic induction Ferrari and weight distribution function of the magnetic field developed good technical success of a stable, high-precision intelligent electromagnetic flowmeter. Flow measurement for a variety of conductive liquid, such as water, sewage, mud, various beverages, chemicals, viscous liquids and suspensions.
Electromagnetic flowmeter works
Faraday's law of induction (refers to when a conductor through a magnetic field is generated in the conductor inside EMF) is the basic principle of electromagnetic flowmeter measurements. This measuring principle can be applied to a conductive fluid, the fluid in the fluid inflow conduit direction perpendicular to the magnetic field, electric potential induced in the fluid can be used to generate a symmetrical arrangement of the two electrodes is measured. Signal voltage UE and the magnetic induction B, the electrode spacing D and V is proportional to the average velocity of fluid. Since the magnetic induction B and the electrode spacing D is a constant, so the signal voltage UE is proportional to the average flow velocity V. The equation used to calculate the volumetric flow rate signal indicating the voltage UE is linearly proportional to the volume flow. Induced voltage signal is converted in the converter indexing, analog and digital output signals.
Electromagnetic Flowmeter Features
• 16-bit embedded microprocessors, computing speed, high precision, programmable frequency-wave excitation at low frequency, improve the stability of flow measurement.
• Full digital processing, anti-interference ability, reliable measurement, high accuracy flow measurement range up to 30:1.
• There are three totalizer within, can forward the accumulated, and the difference between the cumulative reverse totalizer respectively, has not power down the internal clock, it can record 16 power-down time.
• Easy to use, just plug in the power supply after installation, without any other operation, you can output standard signal, easy to use non-professionals.
