The flow rate was adjusted by changing the valve opening in supply pipe direction and reading the rotameter
986 was used, and the actual flow rate was measured with a Yokogawa rotameter
Overland flow was supplied by a constant flow regulated with a rotameter
and applied via a reservoir attached to the upper end of each soil plot to maintain a uniform flow depth over the entire soil surface.
1114C Ie Make Purge Type Glass Tube Rotameter

Because of the high altitude of the study site, we corrected for atmospheric pressure changes during rotameter
calibration in Madison, Wisconsin (Caplan 1985).
The flow rate of the atomizing air was controlled and measured using the air pressure regulating valve and the calibrated rotameter
The air flow rate was measured using a rotameter
at the entrance to the gasifier.
The sampling train consisted of the impactor followed by a HEPA filter, calibrated rotameter
, and pump.
The uncertainty in the measurement of flow rate in the case of digital rotameter
(DR) was [+ or -]1% full scale, while uncertainty in the case of analog rotameters
(R1, R2, R3) was [+ or -] 0.
The filtered air, delivered from a rotative compressor, was controlled by a pressure regulator (PR) and a valve (V5), and measured using a calibrated rotameter
The produced gas was then passed through the rotameter
at atmospheric pressure to measure produced gas rate and wet test meter to meter the total gas production.
