LC-M series meter is positive displacement meter for liquids; it is a kind of bulk fuel flow meters. They are designed for bulk liquid metering both in transfer and process control applications; it is perfect for oil and fuels bulk flow measurement.
Working principle of Positive displacement flow meter
The meter consists of 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.
Advantages of LC-M series positive displacement flow meter
-
Excellent stepless adjusting mechanism allows a micro adjustment of the meter
-
High accuracy and repeatability over the wide strange of flow, superior accuracy at constant flow
-
Low maintenance, no metal-to-metal contact in measuring chamber, long life service Low pressure loss, a true gravity flow meter
-
High accuracy flow measurement regardless of pressure fluctuations, temperature variation, viscosity change
-
Positive displacement flow meter accessories include air eliminators, strainers, valves, and a choice of mechanical or electronic registers and printers for presetting, totalizing deliveries, and printing tickets.
