Fluke Molbox/Molbloc Mass Flow Element 1E3-S , 1E5-VCR-V-Q w/ Molstic-S Dual OS12
Fluke Mass Flow Element 1E3-S, (LP) 200 SLM Air
Fluke Mass Flow Element 1E5-VCR-V-Q (DS) 100 SLM N2
Fluke Molstic-S Mounting System: Dual Range 1/2
- 1E3-S: A Fluke molbloc-L Laminar Flow Element with a low pressure (LP) calibration profile. It supports up to 200 SLM (Standard Liters per Minute) of Air.Â
- 1E5-VCR-V-Q: A high-capacity, low differential pressure Fluke 1E5 molbloc Element optimized for a downstream (DS) calibration profile. It supports up to 100 SLM of Nitrogen (Nâ‚‚).Â
- VCR: Indicates the hardware relies on ultra-clean, high-purity VCR metal gasket face seal fittings. The 1E5 uses larger 0.375-inch VCR male end fittings to reduce flow restriction.Â
- V-Q: Specifies the use of Viton (V) internal seals/O-rings combined with a high-accuracy Quartz (Q) reference calibration path.Â
- Extreme Accuracy: Delivers a measurement uncertainty down to ± 0.125% of reading when paired with a modern Fluke molbox1+ Flow Terminal.
- No Moving Parts: Uses a stable, mechanical laminar flow path (the minute annular gap between a piston and a cylinder bore) to guarantee long-term calibration stability.
- Integrated Diagnostics: Features built-in real-time gas temperature conditioning and multi-point temperature measurement directly inside the element body.
- Software Automation: Fully compatible with COMPASS for Flow software, enabling step-by-step automated calibration sequences for connected devices under test.
