The battery-powered electromagnetic flow meter converter adopts internal battery power supply without external power supply. It is suitable for working conditions where the field power grid cannot be reached and the power grid is difficult to lay. It is especially suitable for the monitoring, metering and settlement of the tap water supply system.
where w (x, y) is the weight function. The excitation mode of electromagnetic flow meter includes DC excitation, sinusoidal wave excitation and low-frequency square wave excitation. In the DC excitation mode, a permanent magnet produces a uniform magnetic field, but will polarize the conductive fluid be polarized.
Place the meter where there is enough access for installation and maintenance tasks. Battery Operated Flow Meter offered by China manufacturer Q&T Instrument Co., Ltd. Buy Tri-clamp Electromagnetic Flow Meter directly with low price and high quality.
This means that battery-powered versions are now commercially available. Also, whereas conventional electromagnetic flowmeters require a minimum fluid conductivity of 10 μmho/cm 3, new versions can cope with fluid conductivities as low as 1 μmho/cm 3.
Electromagnetic flowmeters, or as they are known by their more common name, magmeters, have become one of the most common flow metering technologies over the past 50 or more years. They are simple to operate, have no moving parts, cause no flow obstruction, and can provide a high level of accuracy and turndown ratio.
The measuring principle of electromagnetic flow meter is based on the assumptions as follows (Michalski et al., 2001): Flowing liquid is characterized by magnetic permeability μ = μ0. The conductivity of the measured liquid is isotropic and not functions of the magnetic field and the density of the liquid such as the Hall effect is excluded.
