Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of LPG Mass Flow Meter, LPG Mass Flowmeter, LPG Flow Meter, LPG Flowmeter, LPG meter, ATEX, IECEx & CE approved.
Sealand have DN03 to DN150 size meters and are developing bigger models. Each meter can be connected with your computer through a USB-to-RS485 converter. The detail steps are as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.

At the same time, patents on polyurethanes appeared in Germany. In 1952, another patent was publicly announced. The inventor of the patent fixed an unmolded polymer insulation polymer in a heat-insulating groove for aluminum alloy profiles by bonding or mechanical force. Then, As you can see today, cutting off the joints at the bottom of aluminum alloy profiles is the prototype of today's "pouring process" technology.
Up to now, many domestic manufacturers have introduced pouring equipment, including imported and domestic ones. Most of these manufacturers have introduced pouring equipment while they are wearing a strip type equipment.
In the process of wearing the strip, the two sections of the aluminum profile are connected by two heat insulating strips, so as to prevent the conduction of heat inside and outside the aluminum section and achieve energy saving.
According to incomplete statistics, there are nearly 100 domestic companies that use imported wear strip production equipment and domestic wear strip production equipment, and less than half of the total number of normal production.
Both the pouring process and the stripping process have good thermal insulation properties and are the development direction of energy-saving aluminum alloy building materials. The country has also clearly pointed out the necessity of the development of cold bridges. The national standard for aluminum alloy heat insulation building profiles will be introduced this year. The market for thermal insulation and energy-saving profiles will become clearer by then.
Cast and strip insulation aluminum profiles
Casting process Insulation energy-saving technology originated in the United States, its main role is to cast a mixture of sealing wax into the middle of the aluminum doors and windows for thermal insulation.
