Roots flow meter, also known as gas waist wheel flow meter, is an instrument that although looks bulky, has very precise measurement. Because its volume is larger than ordinary flow meters, many people are not optimistic about it, but it is still one of the most precise instruments currently.

Roots flow meter product introduction:

The rotor has good consistency and symmetry, ensuring good repeatability.

Accurate measurement can be maintained even when the flow rate changes greatly.

It has small initial flow rate, small pressure loss and wide range ratio, and is suitable for measuring micro-flow.

Special processing technology makes the flow meter operate more reliably and have a longer service life.

Made of aluminum alloy, small in size and light in weight, it is more convenient to install and maintain.

Advanced microcomputer technology and high-performance microcontroller make the whole machine more powerful and superior in performance.

   The intelligent integrated design can dynamically detect the temperature and pressure of the medium, perform automatic compensation and compression factor correction, and directly display the standard instantaneous volume flow rate and standard total volume of gas.

Using RS485, RS232C, MODBUS protocols, it can be matched with a dedicated MODEM to build an automatic meter reading management system through the telephone network, with a high degree of automation.

Through the above understanding, we know that although the Roots flow meter looks large, it is easy for people to be confused by its appearance and think that its technology is immature. However, on the contrary, it has higher measurement accuracy than those small flow meter, so we need to have a deeper understanding of this unique flow meter.
