In tropical countries such as the Philippines, there are a large number of rice husks ... and of course there are a large number of termites. Recently, a team of students from the University of California Riverbank Engineering decided to use rice hulls to make particleboards that can resist termites. In general, chipboard is made by sticking wood chips together. Unfortunately, termites will eat these woods when used in construction or other areas. This can also happen in plywood and bamboo. On the other hand, the rice husk contains silica, which makes it difficult for termites to consume them. Also, rice husks are rich in resources and are often used to make beds for farm animals. According to statistics, the 4x8 foot (1.2x2.4m) rice husk plate value is about 18 US dollars, while the traditional wood chips of the same size are currently priced at about 25 US dollars. Another disadvantage of wood chipboard is that the glue used in the production process contains formaldehyde, which releases harmful gases. The epoxy resin used by students is also harmful. They are considering using vegetable tannin or casein in milk instead of epoxy to solve this problem. So far, the tannin rice hull plate has sufficient strength but lacks water resistance, and the casein board has reached the waterproof effect but the strength is insufficient. These problems can be solved by using a waterproof coating, or by adding shrimp shells or rice straw with straw to increase strength. Other possible or current applications of rice husk are: as a source of silicon nanoparticles in batteries, as a "green" cement ingredient, as an environmentally friendly plastic material, and as a biochar material for reducing greenhouse gases.

Sealand is a trustworthy supplier of Mass Flow Transmitter, Mass Flow Sensor, Mass Flow Metre, Coriolis Metre, ATEX, IECEx & CE approved.
Sealand 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.
