Applications
Top loading arm inclination homing coupler
The AW–GC-U type homing coupler is suitable for top loading arm. It mainly automatically detects whether loading
arm are homing to locking device of loading arm bracing during use, at the same time outputs general dry contact signals
to batch controller and other automatic control systems to realize effective loading safety interlock control.
The equipment meets requirements of relevant safety standards, and is especially suitable for loading and unloading of
flammable and explosive liquid petrochemical products.
Features
Homing coupler is an intrinsically safe instrument with ultra-low power consumption.
Homing coupler mainly judges inclination angle of loading arm to determine whether it is homing, and is suitable
for various top loading arm;
AL2543 Bottom loading homing coupler
AW–GC-2543 type loading arm homing coupler is suitable for AL2543 bottom loading arm. It mainly
automatically detects whether loading arm is homing to locking device of loading arm bracing during use, at the
same time outputs a dry contact signal to batch controller and other automatic control systems to realize effective
loading safety interlock control.
Homing position provides homing detection for liquid phase loading arm and gas phase loading arm, and is
installed on the short arm locking device of liquid phase and gas phase of loading arm bracing. When loading arm
is hung into the locking device, Sensor of homing coupler can accurately Reliably judge whether loading arm is
locked, so as to detect whether loading arm returns to its original position.
The equipment meets the requirements of relevant safety standards, and is especially suitable for loading of
flammable and explosive liquid petrochemical products.
Features
Homing coupler is an intrinsically safe instrument with ultra-low power consumption.
The shell of the equipment is made of high-strength aluminum-magnesium alloy shell material, which is strong,
reliable, beautiful and durable, easy to install, and can be installed or modified on site without fire;
Homing coupler provides liquid phase loading arm and gas phase loading arm homing detection;
AL2543 Loading Arm Connection Detector
AW–SL2543 Loading Arm Connection Detector is suitable for detection of connection between loading arm
quick coupler and tank truck port, judging whether connection between loading arm quick coupler and tank truck
port is in place, outputting the general dry contact signal to batch controller and Other automatic control systems,
realize effective loading safety interlock control.
The equipment meets requirements of relevant safety standards, especially suitable for loading and
unloading of flammable and explosive liquid petrochemical products.
Features
The detector is an intrinsically safe instrument with ultra-low power consumption.
The core part of detector is handle and its internal magnetic induction element, which is made of aluminum alloy
and stainless steel, which is strong, reliable, beautiful and durable, easy to install, can be installed or modified on
site without fire;
Anti-slip alarm
AW–CS type Anti-slip alarm is mainly equipped with quantitative loading control system. The moving alarm
distance can be set on batch controller. Once moving distance of tank truck exceeds set value during loading
process, batch controller will immediately Close valve and close pump to stop and load the vehicle to realize
effective loading safety interlock control.
The equipment meets requirements of relevant safety standards, especially suitable for loading and
unloading of flammable and explosive liquid petrochemical products.
Features
The controller is an intrinsically safe instrument with ultra-low power consumption.
Small structure, small installation space.
Long measuring stroke (100-1300mm optional), high precision (0.3%FS), protection class IP65.
Shell and wire wheel have been treated with anti-corrosion, Traction rope is made of stainless steel coated with Teflon,
can work in harsh environments.
Optional output modes are: current, absolute pulse type.
Features
The manager is an intrinsically safe instrument with ultra-low power consumption.
Shell of manager is made of stainless steel shell material, which is strong, reliable, beautiful and durable;
The key jack of manager is versatile and can be inserted into various keys;
Voice prompt controller
AW–VP voice prompt controller is mainly equipped with a quantitative loading control system, which provides voice
prompts for process during loading process and voice alarms for various safety alarms during loading process. It uses
RS485 communication mode and provides MODBUS RTU protocol, supports up to 200 voice content, controlled by batch
controller, PLC and DCS. The controller facilitates driver's operation and enhances safety alarm of loading process.
The equipment meets the requirements of relevant safety standards,especially suitable for loading and unloading of
flammable and explosive liquid petrochemical products.
Features
Controller is an intrinsically safe instrument with ultra-low power consumption.
Controller shell is made of stainless steel shell material, which is strong, reliable, beautiful and durable;
