Liquid Controls
Liquid Controls is the maker of the original tri-rotor positive displacement flow meter, a design patented in 1954 and first used by the U.S. Air Force, and today an IDEX Energy brand. Its meters measure refined fuels, aviation fuel, LPG, ammonia, crude oil and industrial liquids for custody transfer, and the LCR.iQ register controls and records the delivery. Seven Star LLC sources and supplies these meters and registers for fuel depots, LPG plants and tanker fleets in Oman.\n\n

Where tri-rotor meters are used
\n\nTypical uses are truck-mounted fuel delivery, LPG bobtail delivery, aviation refuelers, bulk plant and terminal loading of tanks, railcars and ships, and industrial transfer of syrups, solvents and oils. The manufacturer points to sustained accuracy, because there is no metal-to-metal contact in the measuring chamber.\n\n

Frequently Asked Questions
What is a tri-rotor positive displacement meter?
It holds one blocking rotor and two displacement rotors in three bores of one housing. The rotors turn in synchronized relationship and divide the liquid into uniform volumes, which are counted without metal-to-metal contact in the measuring chamber.
Which liquids can Liquid Controls meters measure?
The range covers refined petroleum products, aviation fuels, LPG and anhydrous ammonia, crude oil, solvents, treated water, syrups and oils. The meter class and materials are chosen for the liquid, so state the product and its viscosity when you enquire.
Which registers go with the meters?
Meters take mechanical registers or electronic registers such as the LCR.iQ, with options for temperature compensation, strainers, air eliminators, printers, valves and pulsers.
Do Liquid Controls meters have weights and measures approvals?
The manufacturer brochure states that its meters meet NTEP, Measurement Canada, OIML and military weights and measures specifications. Approvals depend on the configuration, so name the approval your authority requires when you ask for a quote.
Is Seven Star LLC a distributor of Liquid Controls?
No. Seven Star LLC is an independent supplier in Muscat that sources genuine Liquid Controls products through commercial channels, checks the model and configuration against the manufacturer documentation, and provides the datasheet with the order on request.
