TUF-2000 has an isolated serial port, the RS485.
TUF-2000 can support more than 4 different communication protocols by the same time; include MODBUS-ASCII, ASCII-RTU, Meter-BUS, the Fuji Extended Protocol and more than 10 compatible communication protocols used by Huizhongs flow meters.
MODBUS is a very commonly used industrial protocol. Both the RTU and the ASCII format of MODBUS is supported
The Fuji Extended Protocol is developed based on the protocol used in a Japanese ultrasonic flow meter. It is totally compatible with that of Version 7 flow meter.
TUF-2000 can be used as a sample RTU terminal. The 4-20mA output in the TUF-2000 can be used to open an analog proportional valve; The OCT output can be used to control the turn-on and turn-off of other devices such as a pump. The analog input can be used to input pressure or temperatures signals.
There is a programmable device address (or ID number) located at window M46. When TUF-2000 is used in a network, all the parameters of the flow meter can be programmed through the network, except the device address that needs the keypad.
At most occasions, data should be obtained by polling the flow mete with a command, the flow meter will respond with what the master asks.
TUF-2000 can also set to automatically output data at a period which is programmable.
The TUF-2000 also has a special command sets to facilitate the use of the flow meter in a GSM network.
