Liquid Controls steel-case MS-Series rotary motion positive displacement (PD) meters deliver exceptional accuracy for bulk custody transfer of various liquids, including petroleum products, aviation fuels, LPG, crude oil, petrochemicals, and industrial liquids.

Design and Construction

  • Shell Structure: Spherical steel-case shell with flanged inlet and outlet ports.

  • Metering Element: Traditional LC design with synchronized rotors for accurate volumetric measurement.

  • Sealing Mechanism: Hydraulic sealing using a stationary boundary layer of liquid ensures low wear and long service life.

Optional Components

  • Inlet Accessories: Bolt-on strainers and air eliminators.

  • Outlet Accessories: Manual or solenoid-actuated valves.

  • Registration Options: Mechanical and electronic registration equipment with printers.

Model Pressure Rating
MS 150 psi / 10.5 BAR
MSAA 275 psi / 19 BAR
MSA 300 psi / 21 BAR
MSB 720 psi / 50 BAR
MSC 1,440 psi / 100 BAR

 

Ideal for petroleum, petrochemical, aviation, LPG, and industrial liquid transfer processes requiring high accuracy and durability.

  • Meter housing: Steel or stainless steel (epoxy coated steel available for aviation and other applications)
  • Meter element and rotors: Cast aluminum (other metalurgies available including cast iron and stainless steel)
  • Internal components: Aluminum, Ni-Resist, stainless steel, iron
  • Seal materials: Buna-N, Viton®, PTFE
  • Bearings: Carbon, PTFE, Ni-Resist

Liquid Controls MS-Series meters meet NTEP (NIST Handbook 44) and International Weights and Measures accuracy requirements as well as U.S. Military specifications.

Class 1 Refined petroleum products, such as  leaded and unleaded gasoline, fuel oils, diesel fuel, kerosene, and ethylene glycol (antifreeze) and propylene glycol.  Also used on motor oils, crop oils and rotogravure ink at reduced rates of flow.
Class 2 Aviation gasoline and jet fuels
Class 3 Variety of products such as: liquid sugars, corn syrup, corn sweeteners, dextrose, fructose, sucrose maltose, lactose, corn oil, soy bean oil, cotton seed oil, coconut oil and shortening’s etc.
Class 4 Treated waters and certain solvents where no red metals are allowed.
Class 7 Chlorinated solvents such as: perchloroethylene, trichloroethylene, trichloroethane and methlyene chloride. Also used for general solvent service.
Class 8 Acid pH liquids such as: nitric, phosphoric, glacial acetic acids, citric (fruit juices) and vinegars.
Class 10 Liquefied petroleum gas (LPG)  including butane, isobutane, pentane, ethane, freons, and propane.
Class 12 Anhydrous ammonia (NH3).
Class 14 Crude oil. For heated and/or viscous liquids including animal fats, resins, #6 oil and non-abrasive asphalt emulsions.
Class 15 Oil or water based latex products, polyester resins, adhesives, herbicides, nitrogen fertilizers.
Class 16 General solvent metering service such as: methanol, toluene, xylene, naphtha, acetone, MEK, MIBK, and alcohols including ethanol (also 200-proof alcohol). Class 7 meters should be used if the
application involves the use of chlorinated solvents
Class 20 Batch process water meter service. May be used for solvents and other liquids compatible with brass.
Class 27 Alkaline pH liquids: latex products, adhesives, some liquid fertilizers (10-34-0).
Class 30 Herbicides such as  such as Aatrex, Atrazine, Bicep, Bladex, Dual, Lasso, Lasso ME, Treflan, Sutan, Sutazine, and Eradicane (requires PTFE seals).
Class 37 Sodium hydroxide (caustic) solutions, high sulfur crude oil (LACT and NOD), and other alkaline pH liquids  including non-abrasive asphalt emulsions, liquid feed (molasses) supplements, and some resins. Construction suitable for heated and/or viscous liquids.
Class 47 Mildly abrasive liquids.
