Alicat Scientific's Whisper mass flow meters and controllers feature low differential pressure ranges
Alicat Scientific's Whisper mass flow meters and controllers overcome the challenges of low pressure systems to deliver accurate metering and control. All Alicat meters and controllers are based on its laminar flow technology. The Whisper Series also incorporates a 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.
Compatible with 30 field-selectable gases and gas mixes, Whisper flow meters and controllers can operate as standalone devices or integrate into process control instrumentation. In addition to mass flow, a single device 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.
