2. Two wire electromagnetic flowmeter specifications
Two wire electromagnetic flowmeter with integrated structure adopts dual frequency excitation method, suitable for pipes of different specifications. The nominal pipe size range is wide, generally ranging from 25mm (1.0 inch) to 100mm (4.0 inches), and explosion-proof types also cover this range. Its working voltage is between 14.7 and 35V DC, using a two-wire system to provide current output, including digital output options, supporting pulse, alarm, or status output. The electrode material is made of high-quality stainless steel JIS SUS316L (AISI 316L SS/EN 1.4404), or Hastelloy C27
6, tantalum, platinum iridium and other materials, which have good corrosion resistance. The fluid temperature adaptation range is -40 to 130 ℃ (-40 to 266 ℉), depending on the model. The ambient temperature is limited to -40 to 55 ℃ (-40 to 131 ℉). For conductivity, flow meters require a fluid conductivity of at least 10 µ S/cm, which is also influenced by nominal pipeline size and fluid conditions. The lining is made of PTFE PFA material, and the surface has been treated with a mirror mesh. The laying length is divided into two types according to the flange size: flange size 80mm (3.0 inches) to 100mm (4.0 inches) and flange size 25mm (1.0 inches) to 100mm (4.0 inches). The flowmeter is equipped with a full dot matrix LCD display, which is easy to operate and comes with 4 electromagnetic switches, including a button
