Parr offers a variety of accessories for its line of pressure reaction vessels to enable the investigator to accurately determine the amount of gas consumed in a reaction conducted at elevated pressures and temperatures. There are essentially two methods used to measure the amount of gas delivered to a reaction vessel. These are:<\/p>\n

1. The measurement<\/strong> of the pressure drop in an auxiliary supply vessel of known volume.<\/p>\n

2. The measurement and integration<\/strong> of the flow rates using an electronic mass flow meter.<\/p>\n

Each of these methods has its advantages and limitations as discussed in the following sections.<\/p>\n
