120/230 VAC power adapter with communications cable 32929-89 and NIST-traceable calibration report supplied by the manufacturer.
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.

Q:For the Cole Parmer RK 32908 - 71 model flowmeter, does the meter measure the flow rate of air at standard conditions or does it correct for thermal effects? My setup has a pressure drop upstream of the flow meter which will cool the air down greatly. I worry if the meter will compensate for this or not.
A:There is a volumetric flow reading which is not compensated for temperature. There is also a mass flow which is corrected to SLPM which is 25C and 1 atmosphere.
