DESCRIPTION: EPD34 FLANGE ANSI 300Lbs REMOTE
EPD34 offers the industry’s widest range of liners, electrodes and sizes to meet the needs of even the most demanding process applications in sectors as diverse as chemical, power, oil & gas and metals & mining. The powerful transmitter is easy to use and provides the output signal that meets your needs. With EPD30 you get a versatile, reasonably priced, most accurate flow meter tailored for your applications. A flowmeter with base functionality, short delivery and a simple and clearly understandable documentation.
EPD34 electromagnetic flow meter is a high-accuracy flow meter manufactured based on the latest international technology. It is widely applied in papermaking, chemical industry, metallurgical industry, drainage, waste water treatment, liquid high-pressure metering, medical care, food, and environmental protection industries.
It is used to measure the non-magnetic liquid and plasma in the enclosed pipe
WORKING PRINCIPLE: EPD34 FLANGE ANSI 300Lbs REMOTE
The working principle of the electromagnetic flow meter is based on the Faraday law of electromagnetic induction. When the conducting liquid flows in the orthogonal direction of the magnetic line direction, it will cut the magnetic lines and generate induced voltage, which shows linear relationship with the flowing speed. Thus, the fluidic volume flow can be calculated.
EPD electromagnetic flow meter is mainly composed of the sensor and transmitter. The measuring tube of the sensor is equipped with the excitation coils upward and downward. The transmitter supplies the excitation current, which generates the magnetic field which goes through the measuring tube once it is powered on. A pair of induction electrodes installed on the inner side of the measuring tube comes in contact with the liquid to guide the induced voltage to the sensor.
