MCD-Series dual-valve mass flow controllers increase experimental possibilities
Tucson, Arizona (December 11, 2013) – Alicat Scientific, Inc.’s new 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.
Alicat’s MCD-Series bidirectional mass flow controllers replace multiple instruments for laboratory use.
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 patented, internally compensated laminar differential pressure measurement yields linear results over a very wide flow range. The resulting volumetric and mass flow data is fully compensated for changes in pressure and temperature and corrected for the user’s standard temperature and pressure (STP). Available 0.4% accuracy +0.2% full-scale repeatability and less than 100ms control response times ensure top performance of gas flow processes.
The MCD-Series’ large integrated display allows users to access setpoint control and PID valve tuning without need for a computer. It comes with 30 field selectable calibrations, and is available in full-scale mass flow rates from -0.5/+0.5 sccm to -3000/+3000 slpm. All units are backed by NIST-traceable calibration, comprehensive technical support, and a lifetime warranty.

and M-Series mass flow meter for micro flows down to 2.5 µl (microliters)will be on exhibit at the MRS Fall Meeting.
Alicat’s instruments enable user programming of control parameters and on-site multi-gas calibration changes, allowing researchers the flexibility needed for exploratory analysis and process engineers the precision needed to maintain batch quality. Launching at the show will be the MCD series dual-valve bidirectional mass flow controller. This single instrument will allow users to control for mass flow or volumetric flow bidirectionally, with or without vacuum, and to control for absolute pressure or backpressure, making it the most versatile mass flow controller currently on the market.
Also on display will be its full line of instruments, based on Alicat’s highly accurate laminar flow technology. Instruments come pre-calibrated for 30 gases and gas mixes, and are backed by the industry’s only lifetime warranty. The PCD series dual-valve pressure controller delivers precision control in closed systems. For high vacuum applications, the MCV series mass flow controllers’ pneumatic shut-off valve enables the tight shut-off parameters required to maintain product integrity. Most of the company’s mass flow meters and controllers are available in micro flow ranges that are accurate down to 2.5 microliters per minute.

The Alicat MCV accurately controls gas flow rates as low as 25 microliters (0.0025 SCCM) or as high as 20 slpm with response times of 50 to 100 milliseconds. An integrated positive shut-off valve provides leak-tight shut-off of 1×10-9 atm-scc/s Helium max, preventing contamination of the coating process when no gas is flowing.
Alicat’s MCV has the industry’s lowest turndown ratio at 200:1, allowing manufacturers to cover a wider flow range with fewer pieces of instrumentation. With a footprint just 1.5 inches deep and weighing just 3 pounds, the space-efficient MCV integrates easily into PV coating systems. All Alicat instruments are based on its highly accurate laminar flow technology, come with 30 field-selectable gas and gas mix calibrations, and are backed by the industry’s only lifetime warranty.

Tucson, Arizona (September 27, 2013) – Alicat Scientific, Inc. will exhibit its Whisper series of mass flow meters and controllers at the Gulf Coast Conference, October 15-16 at the Moody Gardens Convention Center (Galveston, Texas). Visitors to booth 604 will learn how the Whisper Series overcomes the challenges of low-pressure environmental systems to deliver accurate metering and control, saving time and money.
Alicat’s Whisper series mass flow meters and controllers are purpose designed for low pressure drop systems used in the environmental industry
Alicat’s Whisper series digital mass flow meters and controllers accurately and rapidly measure or control the mass flow rate, volumetric flow rate and pressure of process gases with minimal effect on the process itself. Featuring 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), the Whisper series has minimal system impact, with faster mass flow measurement (<10 ms) and control (<100 ms).
Manufacturers of gas analysis equipment and specialty gas suppliers will be shown how Whisper series instruments eliminate the need for larger pumps or supply sources, higher feed pressures, or increased bottled gas to overcome pressure drop requirements. Complete with 30 field-selectable gas and gas mix calibrations, Whisper series flow meters and controllers can operate as standalone devices or be integrated easily into process control instrumentation. Extensive customization options are available including Class 1. Div 2 ATEX/CSA ratings for use in hazardous environments.

Tucson, Arizona (April 16, 2013) – Alicat Scientific, Inc.’s new line of mass flow meters and controllers overcome the challenges of low pressure systems to deliver accurate metering and control. The Whisper series saves time and money in semi-conductor and other process industries with systems using very low pressure differentials or exotic gases.
Alicat’s Whisper series saves time and money in systems using very low pressure differentials or exotic gases.
All Alicat meters and controllers are based on its patented laminar flow technology, resulting in fast and accurate responses. The Whisper series also incorporates a very low differential pressure sensor and redesigned flow body to achieve a differential pressure range of .01PSID to 2.0PSID, depending on flow rate and configuration. Prior to Whisper series instruments, users relied on larger pumps or supply sources, higher feed pressures, or the use of more bottled gas to overcome pressure drop requirements imposed by mass flow instrumentation.
Compatible with 30 field selectable gases and gas mixes, Whisper flow meters and controllers can operate as standalone devices or integrate easily into process control instrumentation. In addition to mass flow, a single device quickly and accurately measures pressure, temperature and volumetric flow. For applications requiring precision gas flow control, Whisper series mass flow controllers deliver accurate flow regulation of gases with the ability to respond to upstream gas flow changes, attaining and maintaining flow setpoints in less than 100ms.
