Advantages and disadvantages of Plastic Rotameter
Benefit: We can use them for liquid, gas, or steam applications. Their design is simple and therefore economical. They are very light (it depends on the measuring tube). They do not need a power supply. Flow readings can be easily performed during installation. Low-pressure drop.
Their accuracy is not very high. A specific calibration is required for each fluid. Usually, they do not have an accumulation function (although for different electronic converters, this function is already provided in the instrument). The flowmeter must be installed in a vertical pipe with the upstream flow, although there are also options for vertical pipes for downward and horizontal flow among the options for metal measuring pipes.
Due to its low price, Solenoid Valve Manufacturer's variable area flow meter is one of the most widely used types in the industry and has generally proven to be one of the most effective solutions for low flow applications.
They are also widely used as simple flow regulators by adding manual regulating valves integrated with the main body of the flow meter. In this way, adjusting non-automated processes is very simple.
Therefore, different sectors, such as water treatment and purification, gas processes, mechanical control and measurement, control and research laboratories, industrial and process refrigeration, chemical pharmacy and cosmetics industries...all these sectors use variable area flow meters, It can be used as emergency control even in case of emergency, power outage.
