Low pressure flow meters
24 May 2013
Overcoming the challenges of low pressure systems to deliver accurate metering and control, Alicat Scientific 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.
