Patent number: 10060837Abstract: Disclosed is a differential pressure volume flow air sampler that measures temperature in a collection cavity, differential pressure between the measured ambient pressure and air pressure in a collection cavity. These parameters are used to calculate the volume air flow across a collection disk using a processor which adjusts a blower to maintain a substantially constant volume air flow through said air sampler from the surrounding atmosphere.Type: GrantFiled: April 21, 2011Date of Patent: August 28, 2018Assignee: Western Energy Support and Technology, IncInventor: Michael S.

Patent number: 9696244Abstract: A sampling device uses two ball valves that may be operated to take a sample while allowing flow to continue in a bypass path in a pressurized pipe. As one ball valve closes, it may capture a sample of liquid and gas that may be traveling in the pipe, then the sample may be discharged through a sampling outlet. The second ball valve may be operated simultaneously to open a bypass path while the first ball valve captures a sample. In some cases, the speed of actuation may be a function of the flow speed to capture an accurate sample. In other cases, the length of pipe from the sampling valve to the bypass junction may determine the effectiveness of the sample when actuation speed is relatively slow.Type: GrantFiled: June 11, 2015Date of Patent: July 4, 2017Assignee: Western Energy Support and Technology, IncInventor: Michael S.
