Alicat MW Series Low Pressure Drop Meters

Accurate: Measure flows with NIST-traceable accuracy for a variety of gases down to 0.01% of full scale, or define your own gas composition with COMPOSER™.
Easy to Use: As soon as you turn on the flow meter, it’s ready to display live flow, pressure and temperature readings in your choice of engineering units.
Connected: Alicat flow meters feature dual digital and analog communications by default and can be ordered with Ethernet/IP, EtherCAT, DeviceNet, Profibus or Modbus (RTU and TCP/IP) communications for easy integration into your digital industrial or laboratory network.

Performance
Available ranges: max 0-1000 slpm, min 0-0.5 sccm/0-500 sμlm (see Part Numbers tab for stock ranges)
Flow measurement range: 0.01% – 100% of full scale.
Standard accuracy calibration, NIST-traceable: +/- (0.8% of the reading + 0.2% of the full-scale range)
Optional high-accuracy calibration, NIST-traceable: +/- (0.4% of the reading + 0.2% of the full-scale range)
Repeatability: 0.2% of the full-scale range
Typical measurement response time constant: 5-10 ms
No warm-up time required
