LC meter selection (by flow rate)a Class 1 Refined petroleum products, biodiesel Class 2 Aviation and jet fuel Class 3 Variety of products including: liquid sugars, sweeteners, syrups, vegetable oils Class 4 Treated waters and solvents where no red metals are allowed Class 7 Chlorinated solvents, ethanol Class 8 Acid pH liquids including: nitric, phosphoric, glacial acetic acids, citric juices, vinegar, ethanol Class 10 Liquified petroleum gas (LPG) Class 12 Anhydrous ammonia (NH 3 ) Class 14 Crude oil, heated products, viscous liquids Class 15 Oil- or water-based latex products, polyester resins, adhesives, herbicides, nitrogen fertilizers Class 16 General solvents, 200 proof alcohol, ethanol Class 20 Batch process water meter service Class 27 Alkaline pH liquids: latex products, adhesives, liquid fertilizers Class 30 Herbicides Class 37 Sodium hydroxide solutions, high sulfur crude oil, alkaline pH liquids Class 47 Mildly abrasive liquids a Standard LC meters (with the exception of the M-10, M-25, M-40 and M-80) are suitable for operation on products with viscosities up to 1,000,000 SSU. b Aluminum-body meters are suitable for intermittent overspeed operation at 125% of rating for clean, lubricating fluids. Consult the factory for details. c Maximum, non-shock working pressure ratings are based on products at temperatures below 160ºF (71ºC). Consult the factory for pressure ratings at elevated temperatures. d 275 working pressure available for meter only. e Recommended operation for Class 8 and Class 20 meters should not exceed 80% of maximum rated capacity. Recommended maximum flowrate may be less depending on viscosity. f M-80 Class Class 2 meter may be operated at flow rates up to 1,000 GPM for a limited period of time on jet fuel only.
