Alicat Showcases MCD and Whisper Pressure Instruments at Pittcon

Flow meters and controllers for a range of lab and process needs
Tucson, Arizona (February 28, 2014) – Alicat Scientific, Inc. will exhibit its newly launched MCD-Series bidirectional mass flow and pressure controllers and Whisper-Series mass flow meters and controllers at the 2014 Pittcon Conference and Exposition, taking place March 3-6 at the McCormick Place Convention Center (Chicago, Ill.), booth 1908.

Alicat’s MCD-Series bidirectional mass flow and pressure controllers precisely and rapidly control mass flow rate, volumetric flow rate and absolute pressure of gases in two flow directions. This flexible dual-valve design is the first of its kind, allowing researchers to replace multiple dedicated instruments and make rapid changes to experimental setups.

User-selectable control modes allow users to switch quickly between mass flow, volumetric flow and absolute pressure measurement and control for maximum flexibility in laboratory use. With a dedicated inlet valve and a dedicated exhaust valve, a single MCD can control upstream and downstream flows, as well as positive pressure or backpressure in both open and closed systems. As a universal control element, it can be used to monitor or control a number of parameter combinations, making it useful in a variety of configurations.

Alicat’s Whisper-Series digital mass flow meters and controllers feature extraordinarily low pressure drops, as low as 3.6 mbar (0.052 psi) at full scale, or 0.018 mbar when fully turned down (200:1 turndown). This minimizes system impact, with faster mass flow measurement (<10 ms) and control (<100 ms). Whisper-Series instruments eliminate the need for larger pumps or supply sources, higher feed pressures, or increased bottled gas to overcome pressure drop requirements.
