VSAN Electromagnetic Flow Meter is a high-performance precision flow measuring instrument specifically designed for measuring the volumetric flow of electrically conductive liquids. Utilizing Faraday's Law of Electromagnetic Induction, the flow meter provides highly accurate, repeatable, and maintenance-free flow measurement across a wide range of industrial applications. Since the meter contains no moving parts inside the measuring tube, it eliminates mechanical wear, pressure loss, and frequent maintenance requirements, making it one of the most reliable flow measurement solutions available for modern process industries.
Manufactured using advanced electronics and high-quality sensor technology, VSAN Electromagnetic Flow Meters deliver excellent long-term stability even under harsh operating conditions. The instrument is capable of measuring clean water, wastewater, acids, alkalis, slurries, chemicals, pulp stock, beverages, and many other conductive fluids with exceptional accuracy.
The flow meter is available in wafer type, flanged type, insertion type, sanitary type, and battery-operated versions to meet diverse industrial requirements. Depending on customer requirements, the instrument can be supplied with PTFE, PFA, Neoprene, Hard Rubber, Polyurethane, Ceramic, or other liner materials, along with SS316, Hastelloy, Titanium, Tantalum, or Platinum electrodes for compatibility with corrosive media.
Designed with a rugged IP65, IP67, or IP68 enclosure, the transmitter ensures reliable operation in demanding industrial environments. Multiple communication options such as 4–20 mA, Pulse Output, RS485 Modbus RTU, HART Protocol, Profibus, and GSM/GPRS-based remote monitoring are available to support Industrial Automation and Industry 4.0 applications.
The transmitter features a large backlit LCD display capable of displaying instantaneous flow rate, totalized flow, velocity, conductivity, alarm status, and diagnostic information simultaneously. Advanced self-diagnostic functions continuously monitor sensor health, cable integrity, and electronic performance, thereby minimizing downtime and ensuring uninterrupted operation.
With excellent reliability, robust construction, superior measurement performance, and low lifecycle cost, VSAN Electromagnetic Flow Meters have become the preferred choice for industries requiring dependable and maintenance-free flow measurement solutions.
The flow meter operates based on Faraday's Law of Electromagnetic Induction. When a conductive liquid flows through a magnetic field generated by the sensor coils, a voltage proportional to the flow velocity is induced across the measuring electrodes. The transmitter converts this induced voltage into an accurate volumetric flow rate. Since there are no moving parts inside the flow tube, the measurement remains unaffected by viscosity, density, temperature, or pressure variations.
