Good quality Weigh System - JJ-LIW BC500FD-Ex Dripping System – JIAJIA
Good quality Weigh System - JJ-LIW BC500FD-Ex Dripping System – JIAJIA Detail:
Function principles
The meter controller collects the weight signals of the measuring tank in real-time
Convert the weight per unit time into an instantaneous flow
PID controller calculates the instantaneous flow rate and the preset value
According to the PID algorithm results, the meter controller outputs 4-20mA analog signals to the regulating valve/inverter to make precise flow control
At the same time, the meter controller accumulates the weight of the material flowing out of the measuring tank. When the accumulated value is equal to the set value, the meter controller closes the valve/inverter and stops the dripping.
Features
Highlight display interface, simultaneously display instantaneous flow and cumulative total
Automatic feeding function
Remote, local switching, and manual and automatic control
Comprehensive status monitoring and chain alarm function
Real-time monitoring of sensor load, convenient for maintenance and troubleshooting
Can coordinate with DCS/PLC through the data bus
Standard RS232/485 dual serial ports, MODBUS RTU communication
Extendable a 4~20mA input and a 4~20mA output Optional Profibus DP interface
Features
Case 1: Weighing flowmeter
1. The weighing method is not affected by temperature, density, installation method, etc.
2. High measurement accuracy
3. No contact with materials, no cross-infection
Case 2: Automatic control of dripping by the instrument
1. Automatic drip control of the instrument

3. On-site operation display, simple and intuitive
Case 3: Meter metering flow, DCS control dripping
1. The weighing method is not affected by temperature, density, installation method, etc.
2. The meter directly provides flow data, and DCS controls the process
3. Fast sampling frequency and high measurement accuracy
Case 4: DCS instruction, meter automatically controls dripping
1. Automatic dripping control
2. The instrument participates in the process
3. Reduce the cost of PLC/DCS software and hardware
