L-Series: Liquid Flow Meters

L-series Liquid Flow Meters simultaneously measure volumetric flow rate, liquid pressure, and liquid temperature in real time.
  • Fast, multivariate data. Millisecond-response times immediately upon powering up, to display liquid flow, pressure, and temperature readings in real-time, in your choice of engineering units.
  • Easy integration. Custom process ports and electrical connectors in addition to your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications options enables easy integration into your industrial process.
