(1) Explosion-proof design for enclosure of the controller and instruments to ensure safety and reliability. Large screen of batch controller displays complete process flow, convenient and intuitive.
(2) RS485 interface communicated with MODBUS RTU protocol. Two modes: manual mode and IC card mode can be set to meet the monitoring requirements for users.
(3) Detail operation instruction during operating. The process bar shows the whole loading process, simple and intuitive.
(4) The flow rate can be controlled dynamically through flow control valve in the whole process to achieve optimal flow rate.
(5) Control the solenoid valves on the pipe of liquid, vapor, liquid collection and nitrogen. The valves could be controlled automatically during the loading process.
(6) Maximum 3 signals of ESD switch could be connected to interlock alarm control system. The signals include anti-static detection switch signal, position switch signal, pressure and temperature signal.
The LNG metering skid is an integrated solution for the LNG tank trailer loading & unloading. It is composed of liquid pipe, vapor pipe, venting pipe, circle cooling pipe, liquid collecting pipe, instrument air pipe and LNG loading arm. All the pipe are controlled by the valves.
Truck Loading and Metering Skid is mainly composed of Frame, Batch Controller, Flowmeter, Electrostatic alarm controller, Pressure gauge and pressure transmitter, Temperature Transmitter, Flow control valve, Emergency shut-off valve, and Safety valve etc., for LNG safe and efficient loading from the storage tank to the truck.
