Low-pressure-drop mass flow meters are well-suited to systems with limited source pressure. Whisper instruments create almost no pressure drop, with values as low as 0.07 PSID.
- 0.01-100 % measurement range (10,000:1 turndown)
- Laminar DP (differential pressure) mass flow measurement technology that measures flow with minimal decrease in downstream pressure
- Instant accuracy, with no warm-up
- 98 standard pre-loaded gas choices: switch easily, without losing accuracy
- Limited Lifetime Warranty: Measures mass flow, volumetric flow, temperature, and pressure
