Description Small Diameter Electromagnetic Flowmeter Low Cost Flow Meter
Intelligent electromagnetic flowmeter consists of two parts, the
sensor and converter. It is based on the work of Faraday's law of
electromagnetic induction, used to measure the conductivity is
greater than 5μS / cm conductive liquid volumetric flow rate, is a
measure of the volume flow of conductive medium for induction
meter. In addition to measure the volume flow of conductive liquid,
it can also be used to measure the volume of a homogeneous
liquid-solid two-phase flow of a liquid suspension of acid and
alkali and other strong corrosive liquids and slurries, pulp and
paper pulp.
Widely used in flow measurement of petroleum, chemical, metallurgy,
textile, paper, environmental protection, food and other industrial
and municipal administration, water conservancy construction, river
dredging and other fields.
