SFE900 electromagnetic flowmeter is a product with high precision and high reliability after continuous upgrading and improvement. The flowmeter has reached the domestic advanced level in terms of excitation technology, lining technology and intelligent technology
Product Description
The electromagnetic flowmeter can handle critical flow applications to enhance accuracy, reduce system maintenance, and meet the demands of challenging liquid conditions. This volumetric flowmeter has no moving parts, making it ideal for wastewater applications or any dirty liquids that are conductive or water-based.
Utilizing an integral welding structure, the device ensures excellent sealing performance.
The structure with no moving components internally is straightforward and dependable, leading to minimal pressure loss.
The instrument demonstrates quick responsiveness, providing an output signal that linearly corresponds to the flow rate with a broad measurement range.
Utilizing low-frequency square wave excitation, the device exhibits excellent anti-interference capabilities and stable zero-point performance.
With excitation fault alarm function and electrode fault data judgment function.
The converter has good interchangeability, and accuracy measurement can be achieved without recalibrating.
Featuring parameter setting storage function, it can restore the original settings with a single key press.
The installation requirements are simple. The front straight pipe section is 5D or above, and the rear straight pipe section is greater than 3D (D is the inner diameter of the instrument).
Equipped with an empty pipe alarm function to prevent measurement errors caused by flow meter data fluctuations due to empty pipe interference.
Only the lining and electrode of the instrument are in contact with the measured medium, so the requirements of corrosion and wear resistance can be achieved on more occasions.
High measurement accuracy with minimal interference from factors such as flow velocity distribution, pressure, temperature, etc., and it supports bidirectional measurements.
The sensor has low power consumption, with the total power consumption of the complete instrument being less than 10VA (DC 10W), irrespective of the sensor size.
Featuring a display angle configuration function, it supports display angles set at 0°, +90°, 180°, and -90°.
The L-shaped meter head design facilitates installation in process industries, as well as parameter observation and data reading.
Magnetic Field Generation: Two electromagnetic coils generate a magnetic field perpendicular to the flow of the conductive fluid inside the meter tube.
Induced Voltage: As the conductive fluid moves through the magnetic field, it acts as a conductor, inducing a voltage.
Electrode Detection: Two electrodes placed on the inner walls of the flow tube detect the induced voltage, which is proportional to the fluid velocity.
Flow Rate Calculation: The induced voltage () is given by the formula:
Where:
Since the pipe’s cross-sectional area is known, the volumetric flow rate () can be calculated:
Where is the cross-sectional area of the pipe.
