Product Description I. Overview Roots flowmeter is used for pipeline flow continuous or intermittent measurements of high precision measuring instruments. It has high accuracy, good reliability, light weight, long life, easy installation features, is typical of positive displacement flowmeter. Roots Flowmeter mainly by the metering chamber, sealing couplings and counter three parts, can now instruct the cumulative flow and instantaneous flow, together with the sender and intelligent traffic control device, enabling remote measurement and control. Widely used to accurately measure the petroleum, chemical, power, metallurgy, transportation, food processing, pharmaceuticals, defense, commerce and other sectors of the oil and petroleum products, chemical solution and other fluids. Second, the principle when the measured liquid flows through the measuring chamber, the pressure in the formation of the import and export meter, waist wheel rotating in this pressure boost. While fixed to the waist by a pair of axle drive gears, the two back wheels to maintain continuous rotation. As the wheel rotates back, the liquid is continuously discharged through the metering chamber flowmeter. The amount of fluid flowing through each of the metering chamber volume four times, by sealing couplings, gear box, after passing the number of rotations decelerated to counter, that indicates the instantaneous flow rate and cumulative flow of liquid. Install sender organization that became the counter with the sender's waist wheel flowmeter. And display instrument or computer systems supporting, enabling remote (quantitative, cumulative, instantaneous, and other functions) automated measurement and control. Third, the technical parameters 1, the working pressure (MPa): 0.6,1.0,1.6,2.5,4.0 2, the working temperature (℃): - 10 ℃ ~ 60 ℃ 3, medium viscosity (mpa.s) 0.6 ~ 150 4, precise grade: 0.5, 0.2 5, flow range: (m3 / h)
