    BELZ―3 DC12V/24V power supply Voltage pulse+three wire 4-20mA current 
    BELZ―3S DC12V/24V power supply Dual voltage pulse
    BELZ―4 DC24V power supply Two wires 4-20mA current+hart 
    BELZ―5 DC12V/24V power supply Voltage pulse+RS485 communication 
    BELZ―6 DC24V power supply Voltage pulse+3-wire 4-20mA current+RS485 communication 
    BELZ―7 DC24V power supply Voltage pulse+three wire 4-20mA current+hart 

The BELZ series flow digital display counter can be matched with various volumetric flow meters to form advanced digital flow meters.

The total cumulative flow, single cumulative flow, and instantaneous flow can be directly read on the flowmeter.

Can achieve wireless remote transmission function,on-site data can be remotely read.

After external power supply,it can also output flow pulses, analog currents of 4-20 milliamperes, and achieve Hart communication and RS485T communication modes, making it a very advanced flow digital display counter.
