Fuji FLR M-Flow PW Time Delta Ultrasonic Flow Meter

Fuji FLR M-Flow PW Time Delta Ultrasonic Flow Meter based on transit- time measuring method. Making full use of the latest electrics and digital signal processing technologies, we realized the equipment with improved anti-bubble performance high accuracy. The communication function (MODBUS: option) is also applicable.

Fuji FLR M-Flow PW Time Delta Ultrasonic Flow Meter General

  • This instrument provides a communication function by RS-485 interface, by which it can transmit and receive data to and from host computer, programmable controller, graphic display panel, etc.
  • When using the RS-485 interface, the communication system consists of master station and slave stations. Up to 31 slave stations (this instrument) can be connected per master station.
    Note that, because the master station can communicate with only only one slave station at a time, a party to communicate with must be specified by the “Station No.” set at each slave station.
  • In order that the master station and slave station can communicate, the format of the transmit/receive data must coincide. With this instrument, communication data format is determined by the MODBUS protocol and M-Flow protocol (our M-flow [Type: FLR]).
  • Please use an RS-232C ↔ RS-485 converter in case of designating a personal computer or other devices which have an RS-232C interface as a master station.
