Product details

FLDC series electromagnetic flowmeter is a fully intelligent flowmeter developed with the most advanced technology in the world. It has many advantages such as high measurement accuracy, high reliability, good stability and long service life. Since product structure design, material selection, manufacturing technology, production and assembly, factory test, every process in the chain follows strict and meticulous standards. Meanwhile, our engineers have also designed a set of the most advanced production equipment and real flow calibration device for electromagnetic flowmeter, so as to ensure the long-term high quality of products in both software and hard ware.

 

Methods can be selected.

1)      high accuracy with 0.2%,0.5%

2)      with 4-20mA output or pulse output, LCD display

3)      Grounding ring material: carbon steel. Stainless steel.

4) power supply:battery power supply

5) explosion-proof grade: Exd II CT3-6

6) flow range can be set from 0~10m/s.

 

Selection of electrode materials The electrode material should be selected according to the corrosiveness of the measured medium. Please refer to the relevant information on corrosiveness of the medium.

Corrosion tests shall be carried out for special medium
