Ultra-Low Pressure Drop Flow Meters and Controllers Conserve Expensive Gases

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.

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.
