Yu Diamond's 2012 net profit increased by -18.42% year-on-year, lower than our expectation. In 2012, the company achieved sales revenue of 551 million yuan, operating profit of 137 million yuan, and deducted non-net profit of 115 million yuan, up 18.52%, -16.86% and -18.42% respectively. Earnings per share were 0.20 yuan, 0.4 yuan per 10 shares (including tax); in the report period, the company achieved a net profit margin of 22.45% and a net asset-weighted rate of 9.50%, down 7.99pct and 2.39% respectively.
The decline in Q4 performance was the main reason for the lower-than-expected annual results. Q4 gross margin and net profit margin were 31% and 8%, respectively, down 18pct and 21pct respectively, which was the lowest since the 16th quarter. The production of single crystals was in line with expectations, and the production and sales of polysilicon-cut micron diamonds were lower than expected.
Zhejaing Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter, Mass Flowmeter, Mass Meter, Flow Meter, Flowmeter, ATEX, IECEx & CE approved. The product range covers different size from DN03 to DN150, and bigger sizes are being developed.
Sealand mass flow meter is designed and produced according to world`s latest Coriolis technology with exelent appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
