Abstract: A selective holding tank draining system can comprise a sensor device configured to receive total dissolved solids (TDS) data of a stored fluid from a TDS sensor, and wherein the sensor device can be configured to receive volume data of the stored fluid from a volume sensor, and a central server configured to determine a selected TDS level for disposal of the stored fluid. In various embodiments, an average TDS level of a drained volume of the stored fluid if draining from two or more tanks can be calculated. Furthermore, the stored fluid volume to drain from each of the two or more tanks to achieve a drained mixture having less than the selected TDS level can be determined.

Abstract: Disclosed are devices and methods for detecting and relaying operating parameters of equipment, devices or liquid, gaseous or solid materials. Embodiments of the invention may be utilized to determine whether equipment is operating within established operating parameters or to detect other characteristics of the equipment, device or material being monitored.

Abstract: A holding tank monitoring system includes a sensor that is preferably located near the input of a holding tank and measures characteristics of the fluid entering the holding tank over time to predict the expected remaining production in the well.

Abstract: A volatile organic compound (VOC) sensor device can comprise a sensor located in proximity to a tank vent of a storage tank, wherein the sensor can be configured to monitor flumes from the tank vent; a controller operatively coupled to the sensor, wherein the controller can be configured to receive a measured input from the sensor, wherein the measured input can be VOC measurement data of the flumes; and a wireless communication device coupled to the controller, wherein the wireless communication device can be configured to communicate with a coordinator.

Abstract: An air monitoring array system can comprise a plurality of air quality sensor devices arranged within a selected area, which can be configured to measure air pollutant levels in the selected area. Furthermore, each of the plurality of air quality sensor devices can comprise at least one sensor operatively coupled to a controller, and a wireless communication device also coupled to the controller. In various embodiments, the controller can be configured to receive a measured input from the at least one sensor. Also, the wireless communication device can be configured to communicate with a central server.

Abstract: A heat exchanger comprising a conduit formed by two elongated channel forming sheets bound and sealed together along facing flat edges by encapsulating plastic extending around the edges of the sheets and extending through matching openings in the flat sheet edges. The encapsulation is preferably carried out as part of the reaction injection molding of a container, with the heat exchanger encapsulated in a wall of the container.
