Digital oval gear flow meter for oil measurement
The oval gear flowmeter is a widely utilized volumetric flowmeter or positive displacement flow meter ( PD flow meter), known for its high accuracy, adaptability to high-viscosity oils, and robust resistance to external interferences. This type of digital oil flowmeter features two oval-shaped gears installed within the flowmeter housing that mesh together. When a differential pressure is present between the inlet and outlet of the flowmeter, the gears rotate, continuously displacing the oil contained within the "flow space" between the gears and the housing. By tracking the number of gear rotations, the volumetric flow of the oil passing through the flowmeter can be determined.
The measurement mechanisms for this PD oil flowmeter include mechanical gear types and magnetoresistive types. For the digital oval gear flow meter supplied by Silver Automation Instruments, the magnetoresistive method is employed. This involves embedding permanent magnets at both ends of the oval gears, with a magnetoresistor positioned above the meshing center of the two gears. Each full rotation of the gear is detected by the magnetoresistor as it senses the magnetic field, generating a pulse current signal. This pulse signal is directly proportional to the oil flow rate. The flowmeter's display instrument (or counter) calculates the flow rate by multiplying the number of pulses per unit time by a proportional coefficient, known as the flow compensation coefficient, specific to the flow rate. As a result, by setting the appropriate compensation coefficient, the flowmeter can deliver oil flow values within its range that meet the required accuracy standards.
