To enhance dynamic behavior, it is equipped with a newly designed, energy-efficient microprocessor that incorporates an innovative multi-stage control loop. The new metal housing is compact yet highly robust. 【Features】 ○ Innovative sensors ○ Unique laminar flow elements ○ Advanced control valves ○ Upgraded electronics *For more details, please contact us or download the catalog.

• controller

It is a direct through-flow type instrument that applies the principle of a constant temperature anemometer.

The gas digital mass flow meter (flow meter) and controller have achieved a flow range coverage from 0.01…0.2 ln/min to 100…5000 ln/min (Air) as a result of continuous performance improvement efforts, resulting in a standardized and extensive product lineup in line with M+W's strategy. The instrument operates with an IP65 protection rating and is driven by a mainboard equipped with all the functions necessary for accurate flow measurement and control. The instrument is provided in commonly used digital or analog input/output forms. In addition to the standard RS232, it also supports communication protocols such as Profibus-DP, DeviceNet, Flow-Bus, and ModBus-RTU as standard options. A key element and innovative improvement is the modern multi-color, multi-function standard option indicator setting device. We offer instruments with an excellent price-to-performance ratio. This instrument can be used in laboratories, production facilities, and many industries. For more details, please download the catalog.
