Sampi SPA IDEX Energy Group

Liquid Controls is a flow meter maker. The site says it is an IDEX Energy brand within Advanced Flow Solutions. Its main office and customer service team is in Oklahoma City, Oklahoma. The company traces its start to 1954, when its founders introduced the first tri-rotor meter.

The company makes M-Series and MSAA meters for refined fuels. It makes MA and MSA meters for liquefied petroleum gas. The site says these meters are the industry standard for safe and accurate LPG transfer. It also makes the LCR.iQ electronic register, which helps fuelers spend less time pressing buttons.

Aviation fuel is one of its markets. The site says its Class 2 aviation meters began in 1956 with the US Air Force. They are still the preferred meter for aviation fueling today, according to the site.

The site describes the meter design as a positive displacement flow meter. It says there is no metal-to-metal contact inside the measuring chamber. The site claims this keeps accuracy over time, with fewer recalibrations and a longer service life.

Fred Wacker was also a racing enthusiast who competed in several major races. The site also has a campaign called LC Salutes that honors fuelers and drivers.
