MA-920 Series Micro Flowmeter
Brand: Tokyo Keiso Co, LtdMA-920 MICRO FLOWMETER is a metal tube variable area flowmeter which has local indication with transmitting of minute flow rate of liquids and gases. TOKYO KEISO's long time production know-how and recent electronics technology have been successfully combined. The existing micro flowmeters generally need a signal linearizer due to mechanical problem of very minute sensing part. In MA-920, integrated microprocessor takes care of these automatic compensation based on individual stored calibration data and achieves high accuracy even for small flow rate. The 4 to 20 mA with 2-wire system makes field wiring easier.
Features- Covers very low flow rates of 0.6 to 3 L/hr
- 2-wire 4 to 20 mA DC output
- Magnetic field sensor detects the float movement with electronics to eliminate hysteresis. High accuracy and repeatability have been achieved.
- Easy to read digital LED display
- No liquid dampers are needed even for gas measurement applications
- Ex d IIC T6 flameproof construction suitable even for Hydrogen atmosphere
