Gas Top Loading Arm With Liquid Level Alarm for Truck
Product Description
Land/truck loading arm is a kind of important fluid transfer equipment nowadays in the petrochemical industry. It is mainly used for transferring the fluid such as petroleum, LNG, LPG, gasoline, diesel, oil, liquid ammonia, EO or other chemicals etc between the pipe system and the tankers.
It mainly consists of pipeline, swivel joint, spring or counterweight balance system, flange, vapor cone or seal cap, level sensor, vacuum breaker, drop pipe deflector, quick coupling, dry coupling, emergency break away coupling etc.
Equipped with loading platform, folding stairs and safety cage, overfilling&grounding alarm, batch controller etc to make the land loading arm into a complete loading system.
According to the products, models and requirements of customers, the operating modes could be manual, pneumatic or hydraulic etc.
Basic characteristics:

Top loading arm is one kind of truck loading arm. It means the loading arm is used for filling top connection of the tank. Depending on the product character, this connection may be open (hole not sealed), closed (seal cap or cone, flange, quick coupling or dry coupling). A closed connection indicates that the product is dangerous or toxic and made by a flange to the top pf the tanker. Sometimes equipped with hose to balance the vapor pressure or prevent the vapor from being released into atmosphere.
