Williams Instrument Company, Inc. was established in 1965 as a supplier of specialized equipment to the USA natural gas distribution industry. Williams revolutionized the natural gas distribution industry by developing a method for the positive injection of mercaptans, chemicals for introducing odor into natural gas. Prior to the use of positive injection, the gas industry used the inaccurate bypass method of odorizing natural gas. The Williams’ design approach, which introduced precision, increased safety in an industry that requires a very high level of safety because the public is a customer.

Chemical Industry

Accuracy, flexibility and performance for the industry’s harshest chemical processes
