Mass flow controllers & meters

The multivariate MQ Series meters and MCQ Series flow controllers measure mass flow rate, volumetric flow rates, and pressures. As a result, controllers can be set up for closed loop control of mass flow while also reporting pressure, or closed loop control of pressure while also reporting mass flow. Each instrument comes with a NIST-traceable calibration certificate demonstrating 2 percent of full scale accuracy.

Instruments come preloaded with up to 98 on-board gas calibrations. Alicat’s built-in COMPOSER gas mixing software can be used to compose up to twenty more custom blends using the standard gas list. Accuracy is virtually unaffected by change in gas type, and full-scale valve range is automatically recalibrated to maintain throughput ranges.

Alicat instruments provide multivariate interface displays, as well as data-rich serial and analogue connections on every instrument, and can be used as either a stand-alone device or responsive integrated system component. Both digital (RS-232, RS-485, Modbus) and analogue (0-5v, 0-10v, 4-20mA) communications can be customised to suit a range of end-user applications. Alicat offers NPT, SAE, downport, and NeSSi process connections. Choices in valve type and orifice size allow for configuring products for the best speed and stability.
