Disclosed herein are embodiments of an apparatus for delivering lost circulation material, particularly cottonseed hulls, into oil and gas drilling pits. The invention discloses two embodiments which are distinguished by the execution time necessary in order to produce the estimate of said quantity of interest and enable a therapeutic diagnosis including in an emergency situation. The device has at least one distribution section in communication with the first opening and with the gas flow passages to distribute the incoming gas flow to the gas flow passages, and at least one gas flow passage section including the gas flow passages, which passage section primarily is adapted to permit heat exchange and to cause a conversion in the composition of the gas. A plurality of cylinders are coupled to the frame. Such sensors can be configured in a distributed sensor network to provide security monitoring.
