It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
Characteristics:
◆RS485 analog output for direct communication to central unit
◆Relay output for connecting external device
◆LED display screen
◆Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
◆Password verification for repeat operation, avoid fault operations.
