The MF4700-Serie: Gas Massflow Meters The advantage to work with extended accuarcy (Display, output signal linearized Voltage or RS485) independent from the gas pressure with selectable different gases. Available features like max./min. flow, accumulated flow rate allow a better process control and knowledge about the gas consumption. MF400-Series are available in 3 different sizes and cover a variety of flow ranges:
  • MF4701...0~100, 200, 500 mln/min **Ø 1 mm, Anschluss: wahlweise NPT1/8, NPT1/4, BSPT1/8, BSPT1/4
  • MF4703...0~1, 2, 5 SLPM **Ø 3 mm, Anschluss: wahlweise NPT1/8, NPT1/4, BSPT1/8, BSPT1/4
  • MF4708...0~10, 20, 50 SLPM **Ø 8 mm, Anschluss: wahlweise NPT1/4, NPT3/8, BSPT1/4, BSPT3/8
