Electromagnetic flow Meter Accuracy Electromagnetic flow Meter accuracy is how close the measurement is to the true value. That means how close the output of the meter is to its calibration curve. Zero Instrument calibration was performed on every meter, within ±0.5% of reading accuracy at the calibrated (typical) flow velocity and within ±1-2% of …
It is known from fluid mechanics that when liquid flows in a pipe, the velocity of each point on the Cross section of the pipe is not equal, but the velocity distribution can become axisymmetric after a certain distance of straight pipe, no matter Laminar or turbulent flow The velocity is maximum at the center …

Electromagnetic flowmeters are connected by flanges. The inner diameter of the sealing washer should be slightly larger than the inner diameter of the pipeline to ensure the steady flow of fluid in the pipeline. Installation should avoid direct sunlight or high ambient temperature, to prevent the excitation coil due to ambient temperature is too high, …

When the measured liquid flows through the sensor, the impeller is forced to rotate under the action of the fluid, and its rotational speed is proportional to the average pipe velocity. The impeller rotating periodically changes the magnetoresistance value of the magnetic circuit, and the magnetic flux in the detecting coil changes periodically, which produces …
Requirements for pipes, the internal diameter of the upstream and downstream piping should same with the turbine flow meter Requirements for the straight pipe section, The flowmeter must be installed on the pipe (the pipe inclines within 50). When installed, the flowmeter axis should be concentric with the pipe axis, and the flow direction should …

When the measured medium passes through the cone measuring tube from bottom to top, the upper and lower ends of the float generate differential pressure to form an upward force. When the lifting force of the float is greater than the weight of the float in the fluid, the float rises, the area of the …
