VA550 Insertion flow sesnor-ATEX
Germany- CS instruments
Description：
As the fluid passes over a heated sensor element, it removes heat and causes a change in temperature. By measuring this temperature change, or determining the amount of energy required to maintain a constant temperature of the heating element, the flow rate of the fluid can be accurately calculated.
The VA550 is an industrial-grade thermal mass flow meter, certified with ATEX II 2D Ex tb IIIC T90°C Db explosion-proof protection, and is designed to be waterproof and UV-resistant, making it ideal for harsh environments.
Developed by CS Instruments Germany, the flow meter features a hot-swappable installation design, allowing it to be inserted or removed at any time without system shutdown, while still ensuring accurate measurement of all types of dry gases.
