Alicat Scientific introduces its new “Whisper” series of mass flow meters (MW) and controllers (MCW) with full-scale pressure drops as low as 3.6 mbar, or 0.052 psi.
The Whisper series combines Alicat’s innovative laminar flow technology with low-drop proportional control valves and high-sensitivity differential pressure sensors for use in systems with very low differential pressure availability.
This innovation is accomplished without compromising Alicat’s standard industry-leading 200:1 turndown ratio, 10-ms meter and 100-ms control speeds and real-time gas selection from 30 on-board gas and gas mix calibrations.
Alicat’s MW and MCW series are available in full-scale ranges from 0-0.5 sccm to 0-500 slpm. The 0-500 slpm controller has the largest full-scale pressure drop in the series, just 47 mbar, or 0.69 psi. Alicat backs every mass flow product with generous customer support and a lifetime warranty, an industry first.
For applications in which minimizing pressure drop is essential, the new Alicat Whisper is quietly leading the way.
When to choose a Whisper
Alicat’s Whisper can be used in a variety of applications, but it is particularly well-suited to applications that have minimal differential pressure availability, such as:
- leak checking
- gas analysis and totalizing
- natural gas applications
For applications that do not require very low pressure drops, Alicat’s standard line of mass flow meters and controllers may present a more economical choice.
