Alicat introduces MCRH 5000 mass flow controller

August 24, 2016 – Alicat Scientific has engineered a mass flow controller with a high top flow rate suitable to a wider range of applications. The MCRH can accommodate flow rates of up to 5000 slpm, without compromising speed or precision of gas control. The controller manages industrial processes with more chaotic upstream fluctuations, such as control of industrial combustion gases, or mass flow into food and packaging processes.

The MCRH 5000 slpm controls mass flow rate, volumetric flow rate, or back pressure of gases in high flow processes. To overcome the poor turndown ratio and slow response of existing methods (such as interlinking a meter with an external valve) Alicat designed a new flow geometry. This design accommodates the higher flow rates, with a low pressure drop of 14.1 psig at full scale. A dual valve design enables a fast 100 millisecond control response time without significantly raising instrument power requirements.

The instrument’s Gas Select firmware includes a library of up to 130 preloaded gases, user selectable in the field. The MCRH 5000 slpm can be programmed with the instrument’s push button menus and onboard display, or via remote connection. Digital communications options include RS-232 or RS-485 serial, Modbus, or PROFIBUS, as well as analog 0-5 Vdc, 1-5 Vdc, and 0-10 Vdc, or 4-20 mA.
