Working Principle For The Metering Body
Macsensor series meter is positive displacement meter for liquids. They are designed for liquid metering both in  transfer and process control applications. Thanks to their design they are  easy to keep and can suit a wide range of applications. The meter consists of a housing where two bladed displacement rotors and a central single blocking rotor turn in synchronized relationship within three cylindrical bores with no metal-to-metal contact within the meter element. Each rotor is supported on either end by a bearing plate through which the rotor shafts protrude.


The bladed displacement rotors, alternately move through the two half-cylinder bores of the meter element, while the single blocking rotor rotates within its bore in such a way as to produce a continuous capillary seal between the unmetered upstream product and the metered, downstream product.

At one end of each rotor shaft is a timing gear. The blocking rotor gear, having twice the number of teeth of each of the displacement rotor gears, rotates at half the RPM of the displacement rotors.

Consideration of Class Types Based on Product:
Class 1 meters: For refined petroleum products like gasoline, diesel, and kerosene.
Class 2 meters: Specifically designed for aviation gasoline and jet fuels.
Class 3 meters: Suitable for a wide range of products including liquid sugars, oils, and corn syrup.
Class 10 meters: Designed for liquefied petroleum gas (LPG) and related products.
Class 14 meters: Ideal for crude oil and heated/viscous liquids.
Class 15 meters: For metering oil or water-based latex products and adhesives.
Class 16 meters: Designed for solvent metering including methanol, acetone, and alcohols.
