The electromagnetic measurement system enables the measurement of flows with minimum conductivity. The minimum speed is usually 0,2 m/s in order to start the measurement and offers high accuracy (0,25% error).
Two formats can be distinguished:
Flow meters to insert in line.
They are installed in line in order to measure the circulating flow by flanges or thread. We also have models for pipes from DN15 to DN1000 and pressures up to 40 bar. Its main advantage is the good accuracy offered and the main disadvantage is that it must be installed as a pipe section.
The most common supplied series are the el EFM-115, MQI 99 y MID1.
Insertion flow meters.
Installation by a “picaje”, this is, they are inserted into the pipe with a thread or flange. Available for pipes 25 mm although they are more frequent in big pipes because the system is more economic (its price is not proportional to the diameter) and they exist version prepared for instalación en carga (installation or change of sensor without changing supply).
The most frequent models are F6.60, F6,61, 2551and 2552.
