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.

1. Soil fertilization. That is, when the base fertilizer, the seed fertilizer or the top dressing is applied, the trace element fertilizer is applied to the soil. Although this method of applying fertilizer has a low utilization rate, it has a certain aftereffect. Industrial waste containing trace elements and slow-acting micro-fertilizers often use this method of fertilization.
2. Seed treatment. Including soaking and seed dressing. When soaking seeds, the seeds are immersed in a trace element solution, the seeds absorb the solution and expand, and the fertilizer enters with water. The usual concentration is 0.01% to 0.1%, and the time is 12 to 24 hours. Seed dressing is to dissolve the trace element fertilizer with a small amount of water, spray the solution on the seed, stir evenly, so that the outside of the seed is stained with the solution and then dry and sowed, generally 2 to 6 grams of fertilizer per kilogram of seed.
3. Root dressing. That is, the trace element fertilizer solution is sprayed onto the plant by a sprayer, and is moved into the plant body through the leaf surface or the pores. A commonly used solution concentration is from 0.01% to 0.1%.
