Electromagnetic induction flow meters An electromagnetic flow meter consists of a sensor and a transmitter. The flow meter is used to measure the volumetric flow rate of conductive fluids and waste water. The measurement is independent of the density, viscosity, temperature and pressure. The conductivity of the fluid must be greater than 5μS/cm. The measuring instrument must not be crossed by fluids carrying solid bodies of high dimension that cannot be considered suspended solids. Head losses are absent and straight stretches reduced upstream and downstream of the instrument are necessary. Several...
