DPS flow rate was calibrated to 10 L/min using a field rotameter
2]-free air of 600-620 ml/min were maintained upstream of the metabolic chambers for all tests using a precision rotameter
(model FL-3802, OMEGA Engineering Inc.
Flow rate is measured with Rotameter
(R) at the inlet.
Velocity magnitude measured with EM-flowmeter and the flow discharge was measured by a Rotameter
device and regulated valve .
The flow rate was adjusted at the beginning of each sampling round to 4 L/min with a rotameter
(model RM67, BGI Incorporated) and checked at the end of that sampling round to make sure that it had remained at 4 L/min during the course of sampling.
The flow rate of hydrogen was adjusted by a rotameter
with remote control.
The airflow rate was measured by using rotameter
Air was introduced into the base of the gas pre-heater via a rotameter
, specially designed for diesel engine exhaust gas was used to measure the flow rate of the exhaust and the same is verified using an orifice meter.
The airflow rate and the pressure were recorded by a rotameter
and pressure gauge.
Test fluids were pumped to the column through a rotameter
with the help of a centrifugal pump.
The volumetric flow rate of the gas feed was measured with a rotameter
