The target flowmeter first appeared in the 1960s and was originally mainly used to solve the flow measurement problem of high viscosity and low Reynolds number fluids. The typical application has gases and liquid field. Gases: coal gas, air, compressed air, hydrogen, natural gas, oxygen, nitrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane,

Earthing rings are normally used or suppress electrical interference at the location of installation for magnetic flow meters. Hence, they are offered in pairs and the installation happens upstream or downstream of the flow meter. The good thing about grounding rings is that their design is meant for installation between the series of magnetic flow

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
