LS Series Liquid Flow Meters Controllers 11600

 Measure flow rate, line pressure and line temperature simultaneously, all in real time.  Alicat’s liquid flow meters offer accurate flow measurement and stable control for water or other liquids, including methanol, iso-propanol, ethanol, ammonia, dimethylether, iso-pentane, thiophene, iso-octane or heptane. All liquid flow meters include bleed screws for easy removal of air pockets.

 
For liquid flow measurement without a control valve, choose our L series of fast liquid flow meters, which measure flow, pressure and temperature in real time. Our LB series adds a rechargeable battery for easy audits of liquid flows outside of your lab. 
 
Instruments in the standard L or LB series are also available with an optional “S” configuration (LS or LBS) for use with corrosive liquids.  In this configuration, the flow body is upgraded to 316L stainless steel and the elastomers to FFKM.
 
Alicat’s liquid 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.  Other build options include your choice of display, output, and flow totalizers as well as performance options.  Need further customization?  Contact us and we’d be happy to help you build the instrument you need.
 
Each liquid flow meter comes with a NIST-traceable calibration certificate and an Alicat operating manual.  Power supply sold separately.
