The Role of Pressure Transmitters and Flowmeters in the Process of Sea Water Desalination

In the process of desalination of seawater, the reverse osmosis method is used. In this method, saline water is converted to fresh water after entering a reservoir through a reverse osmosis membrane module. Monitoring equipment is required for this system. A special integrated electromagnetic flowmeter and a special vortex flowmeter are designed for this purpose.

The Integrated electromagnetic flowmeter:

This type of flowmeter is suitable for raw water environments with conductivity higher than 5uS / cm, ± 0.2% F, or ± 0.5% FS accuracy is for option.

Different output signals are accessible. The product features a backlit wide temperature LCD display, which is intuitive to display, and complete functions, handy to operate, decreasing the problem of on-site use and maintenance.

The vortex flowmeter:

The Role of Pressure Transmitters and Flowmeters in the Process of Sea Water Desalination

This type of flowmeter is particularly used for flow measurement of ultrapure water. It is appropriate to set up at the water outlet to monitor the flow of purified water. The product has a particularly designed high-quality guide vane, which significantly decreases wear and tear. It is sensitive and may reliably monitor data in hostile environments. The output signal is pulse output, which is simple to digitize. The accuracy can usually reach ±0.5%R, ±1.0%R to warrant precise measurement.

The most crucial phase in the complete desalination procedure is to apply a high-pressure pump to compress the pure water withinside the seawater.

In addition, special intelligent liquid level switches and smart pressure switches have been designed and produced which could visualize process pressure and switch contact status via analog output, switch output, and a display. They offer several output configurations for specific applications. The switch has a delay setting and supports range scaling of more than 25% FS. It presents functions such as manual zero reset, base point, and peak value display that can efficaciously display whether or not the water flow pressure reaches the established pressure value and control the size of the water flow, so that the high-pressure pump is more precise whilst compressing.

The transfer has a put off-putting and helps variety scaling above 25% FS. It presents capabilities consisting of guide 0 reset, base point, and top fee display, that can efficaciously display whether or not the water goes with the drift stress reaches the setup stress fee and manipulate the dimensions of the water go with the drift so that the high-stress pump is greater correct whilst compressing.
