1.  Cast iron construction, widely used for metering various oil products and liquids that do not corrode cast iron.

2.  Cast iron oval gear flowmeter, with aluminum alloy gears, is applied to the measurement of low viscosity, low radiation liquids (such as gasoline).

3.  Cast steel material, utilized for metering high-pressure, low-corrosive liquid media.

4.  Stainless steel construction, extensively used in measuring highly corrosive liquid media, including acids, alkalis, salts, and organic compounds.

5.  Lightweight oval gear flowmeter, commonly used for metering low-corrosion liquid media, such as water.

6.  Micro-flow oval gear flowmeter, specifically suited for precise measurement of minute flows in boiler fuel, oil products, chemicals, and other liquids.  Made of stainless steel, it is capable of measuring micro-flows of beverages like alcohol, milk, vegetable oil, and other liquid foodstuffs.
