Scully Signal Company

Scully Signal Company designs, engineers and manufactures liquid detection and handling systems for the safe loading, transport and storage of petroleum and chemicals. Founded in 1936 by Francis P. Scully and now in its third generation of family ownership, the company is headquartered in Wilmington, Massachusetts, with sales and service support across Europe, Africa and worldwide. It has operated for more than 85 years and is described as an industry leader in overfill prevention, static ground verification and liquid transfer equipment.

The company's products are built around a self-checking, dynamic fail-safe engineering approach. Its overfill prevention systems pair sensors installed at loading racks with sensors in vehicles to prevent dangerous overfills during loading, transporting and storage operations. Static ground verification equipment confirms grounding to increase safety during liquid transfer, while its liquid transfer equipment is engineered to improve transfer safety and to reduce operational and liability costs.

Scully Signal serves the petroleum, chemical, fluid handling, liquid transport and storage, and loading rack industries. Technical work spans fluid detection, fail-safe sensor systems, overfill prevention and liquid transfer equipment.
