Installation Requirements & Safety Instructions

Installation Environment

• Install the equipment indoors only
• Ensure good ventilation
• Avoid wind, rain, and direct sunlight

Do NOT install the equipment in the following conditions:

• Where temperature or humidity exceeds operating limits
• Areas containing corrosive, flammable, or explosive gases
• Environments with excessive dust, salt, or metal powder
• Locations where water, oil, or chemical liquids may splash
• Areas subject to strong vibration or mechanical impact
• Near electromagnetic interference sources

Electrical & Environmental Protection

• Use appropriate shielding measures when installed near:
  • Power lines
  • Strong electric or magnetic fields
  • Static electricity sources
  • Electrical noise or AC contactors

Maintenance & Cleaning

• Perform regular maintenance to extend equipment life
• Do not disassemble or repair the unit yourself
• Clean only with a soft, dry cloth
• Do not use alcohol, gasoline, or organic solvents, as they may cause discoloration or deformation

Emergency Notice

If water ingress, smoke, unusual odor, or abnormal noise is detected:

1. Immediately disconnect the power
2. Stop using the device
3. Contact the supplier or manufacturer promptly

Measuring Box Dimensions

• Width: 350 mm

• Height: 450 mm

(Custom pump and valve control available:
AC220V / AC380V, 2.2kW–5kW for high-power pumps or special applications)

Key Button Functions

1. Start

• Starts the quantitative program after setting the target value

• For multiple batches or different units (L, Kg, t), configure parameters first, then press Start

2. Pause

• Temporarily pauses the operation

• Pump and valves stop

• Press again to resume

3. End

• Terminates the quantitative task immediately

Product Overview:

This quantitative controller uses a high-performance PLC + HMI touch interface, compatible with:

• Turbine flow meters

• Vortex flow meters

• Electromagnetic flow meters

• Solenoid valves and pump systems

It is designed for flow accumulation and precise dosing control.

Applications

• Petroleum & chemical industries

• Pharmaceutical production

• Food & beverage processing

• Quantitative filling, batching, loading, discharging, gas filling, and material dispensing

Key Features:

• Intuitive visual HMI interface

• Compatible with most flow meters and fluid media

• Multiple measurement units: L, m³, Kg, t

• Safety protections:

  • Flow interruption alarm

  • Pump overload protection

  • High / low liquid level alarm (optional)

• Data recording:

  • Power on/off logs

  • Quantitative operation records

• Cumulative reports for total and batch flow

• Modbus RTU communication

• Permanent data storage (retained after power loss)

Technical Specifications:

• Display: 7-inch industrial touch screen

• Controller: High-performance quantitative accumulation chip

• Flow Input: Pulse signal (<5000 Hz, DC 24V)

• Relay Outputs:

  • 3 relays

  • 3A @ 250VAC / 5A @ 24VDC

• Power Supply:

  • AC 220V / 380V, 50Hz

• Custom outputs available upon request

Terminal Descriptions (Main Connections)

• 485A / 485B: Modbus communication

• 24V / 0V: Flow meter power supply

• Pulse Input: DC 24V pulse signal

• Current Signal Input: Optional

• L1 L2 L3 N: 3-phase power input (5-wire system)

• U1 V1 W1: Water pump power output

• Large Valve / Small Valve: Solenoid valve control

⚠️ Proper grounding is mandatory for both controller and pump to ensure safety and reduce interference.

Operation Interface:

Main Control Screen

• Instantaneous Flow: Real-time flow display (read-only)

• Quantitative Setting: Target dosing value

• Quantification Times: 1–100 cycles

• Current Quantitative Value: Real-time dosing progress

Control Buttons

• Start

• Pause

• Stop

System Notices

• Automatic stop and alarm if flow signal is lost

• Liquid level alarms available as optional features

Parameter Settings Overview:

• Flow meter coefficient (pulse mode)

• Measurement range (current mode)

• Large valve advance closing

• Small valve advance closing

• Pump advance shutdown

• Pump start delay

• Batch interval time

• Cut-off alarm flow/frequency & delay

• Density (for mass measurement)

• Measurement units selection

• Pulse mode / Current mode selection

Pulse mode is recommended for higher accuracy and wider applications.

Manual Control Mode:

Manual operation is available only when the system is stopped:

• Large valve ON/OFF

• Small valve ON/OFF

• Water pump ON/OFF

⚠️ Pump can only start when at least one valve is open.

Data Recording:

• Total accumulated flow

• Last batch quantitative value

• Automatic overwrite when memory is full

• Manual data clearing available (irreversible)

Alarm History:

• Records all system alarms

• Useful for maintenance analysis

• Alarm records can be cleared manually (cannot be recovered)
