Abstract:
1. A portable self contained weather resistant low voltage flow control system comprising: a. an enclosure comprising a body with a movable door; b. a bulkhead disposed in the body forming a top compartment and a bottom compartment; c. at least two batteries disposed within bottom compartment; d. a back plane mounted to at least the bulkhead within the top compartment for supporting electronic equipment; e. a wireless communications unit mounted to the back plane, wherein the wireless communication unit is in connection with the at least two batteries; f. a remote terminal unit mounted to the back plane in communication with the wireless communication unit and the at least two batteries; g. an input/output (I/O) termination assembly mounted to the back plane, wherein the I/O termination assembly provides connections for at least one piece of field equipment to the remote terminal unit; h. at least one uninterruptable power supply mounted to the back plane for providing between 10 volts to 30 volts of DC power to the at least two batteries; i. an A/C terminal assembly mounted to the back plane for receiving and distributing a continuous flow of A/C current from an external A/C power source to the at least one uninterruptable power supply; j. a surge protector mounted to the back plane for protecting the A/C terminal assembly from power surges from the A/C power source; k. a low voltage distribution block mounted to the back plane in communication with the at least one uninterruptable power supply; l. a DC-DC converter mounted to the back plane and connected to the low voltage distribution block; and m. at least two removable lifting eyes secured to the enclosure for lifting of the enclosure by a crane; n. at least one movable door fastener to secure the movable door to the enclosure, wherein the movable door comprises a door extension and wherein the door extension is adapted to house a remote terminal unit monitoring controller in communication with a flow controller in communication with the A/C terminal assembly and at least one piece of field equipment; and wherein the door extension has a viewing port in communication with the A/C terminal assembly and at least one piece of field equipment; wherein the flow control system provides 12 volts to 24 volts of continuous power to the remote terminal unit and the wireless communication unit while providing continuous communication for at least intermittent monitoring of field equipment.
