Versatility and high accuracy from a laminar-based mass flowmeter Accuracy of ±0.8% of reading ±0.2% full-scale; repeatability of ±0.2% Measure 30 standard gases—user selectable from display 100 to 1 turndown with ranges of 1 SCCM full-scale up to 1000 SLPM Models with 4 to 20 mA output or totalizer are available These meters measure flow via pressure drop across a laminar flow element (LFE). Because the flow element makes the flow stream laminar, placement in the process does not require straight pipe runs upstream or downstream of the meter, greatly simplifying installation. As compared to thermal mass technologies, the LFE design provides an ultrafast response within 10 milliseconds and offers “instant on” with no warm-up time. An integrated keypad around the display is all that is required to program the unit for service. The 0 to 5 VDC output allows transmission of the flow value to a remote display, recorder, or controller regulating a valve or pump. For portable flow metering applications, order the battery pack listed under accessories. What's Included: 120/230 VAC power adapter with communications cable 32929-89 and NIST-traceable calibration report supplied by the manufacturer.
