Mass Flow Controllers & Meters

Mass Flow Controllers & Meters

Overview

Fast mass flow controllers and mass flow meters make process control and calibration processes more efficient. Alicat offers many ways to customize your gas flow meter or controller for use in low pressure drop, high pressure or corrosive applications. Standard features include real-time readings, fast valve response and multi-gas calibration. Most models can be customized for flow rates as high as 5000 slpm or as low as 2.5 sµlm/0.0025 sccm.

CODA Coriolis Mass Flow Meters and Controllers

Open in new window

Alicat’s new series of Coriolis instruments offers direct mass flow measurements for exceptional accuracy in a broad array of precision ultra-low flow and high pressure applications. CODA mass flow meters and controllers are compact and pair fast response times with exceptional zero stability to create an industry leading precision instrument. Designed to be highly insensitive to external vibrations, our Coriolis units provide unwavering accuracy throughout the 0.2 g/h to 10 kg/h measurement range.

Versatile. Even when you don’t know the chemical composition of your fluid, CODA enables you to obtain accurate readings of mass flow rate for both liquids and gases. This makes CODA ideal for applications with changing or unknown fluid compositions.
Accurate. Measure flows with NIST-traceable accuracy for liquids and gases down to 0.05% of the full scale flow rate. Our Coriolis instruments are also highly insensitivity to external bumps and vibrations, ensuring accurate measurements despite environmental interference.
Robust. CODA covers more applications for you with resistance to corrosive fluids, an IP67 rating, and operating pressures up to 4000 PSIA. All-metal seals are additionally available with our CODA meters.

High precision liquid and gas measurements independent of fluid composition.

Multi-directional Gas Flow Controllers

Open in new window

Sometimes a process is too complex for a standard mass flow controller. Alicat’s multi-directional mass flow controllers consolidate into one instrument what would otherwise require two or three separate devices.

When you need to control flow in two directions, choose the world’s first bidirectional mass flow controller, Alicat’s MCD series. This versatile instrument can control flow into a closed volume and then control flow in the other direction to exhaust the volume. Or, you can use vacuum to control your process flow in one direction and then apply positive pressure to purge the line in the other direction.

The MCDW applies our Whisper technology with low pressure drop to bidirectional applications like breathing simulations.

Choose the MCT series if you want to control flow in only one direction, but you need to switch the sources of flow or its destinations downstream. Dual valves located upstream, downstream or in both locations help you manage your flowing processes more efficiently.
