M series meter is a 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 a 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.
3.0 Typical Application:
Check the loading/unloading operations of fuel and petrochemical products in fuel bulk plants and/or refineries
On-truck tanker for fuel/LPG transport and delivery
Heavy-duty fuel dispensing system for big vehicles and aeroplanes
Typical Application of Aluminum Construction
Class 1 meter: refined petroleum products, such as gasoline, fuel oil, diesel fuel, kerosene,
ethylene glycol, motor oils and rotogravure ink.
Class 2 meter: aviation gasoline and jet fuels.
Class 3 meter: a wide variety of products such as liquid sugars, corn syrup, com sweeteners,
dextrose, fructose, sucrose, maltose, lactose, corn oil, soybean oil, cotton seed oil, coconut oil,
and shortening etc. rate of flow is based on viscosity-to pressure loss relationship.
Class 10 meter: liquefied petroleum gas(LPG) including butane, isobutene, pentane, ethane,
freons and propane.
Class 14 meter: crude oil, also for heated and/or viscous liquids including animal fats, resins,
#6 oil and non-abrasive asphalt emulsions.
Class 1 5 meters: for metering oil or water-based latex products, polyester resins, and adhesives
(neutral pH). also available for metering herbicides and nitrogen fertilizer solutions (requires
Viton and Teflon seals).
Class 16 meter: for general solvent metering, such as methanol, toluene, xylene, naphtha,
acetone, MEK, MlBK, and alcohols including ethanol.
