MODEL CR-400 Mass Flow Meter
The CR-400 readout unit, when connected to your mass flow control-ler or meter with a cable, provides the key mass flow functions, such as flow measurement and control as well as cumulative flow calcula-tions and flow event outputs. This readout unit offers RS-485 commu-nications capability, so multiple readout units can be controlled online by a host computer. * The CR-400 is fully compatible in size with the CR-300.
Features :
• Total flow is displayed in 8 digits : The upper 4 digits and the lower 4 digits are shown alternately.
• Various event outputs are available.
• With a width of 73mm and height of 73mm, it takes up little space.
• Equipped with forced open/close operation of mass flow controller valve.
• External control terminals are provided on the rear for remote control
• Mass flow control by RS-485 communications
• A lock key prevents accidental operation.
• Mass flow power : ±15 VDC (300 mA)
• Mass flow power: ±15 VDC (300 mA)
