358 Series L Liquid flow meters
Multi-parameter laminar liquid flow meter.
358 Series L Liquid flow meters designed to measure volumetric flow, liquid pressure, and liquid temperature across flow range from 0.5 mL/min to 10 L/min 2% to 100% of full scale.
Millisecond-response times immediately upon powering up, to display flow, pressure, and temperature readings in real-time, in your choice of engineering units. Backlit LCD readout (Optional color TFT dispay)
Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Profinet, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.
Also available in Portable Battery Pack or anti-Corrosive option.
