1. An apparatus for controlling flow in a fluid distribution system, comprising: a flow sensor configured to determine a flow of a fluid through a conduit of a fluid distribution system, wherein the fluid is a liquid;a valve associated with the conduit and coupled to an actuator; and a controller connected to the flow sensor and the actuator,wherein the controller includes logic configured to: receive a flow target associated with a device of the fluid distribution system;cause the actuator to actuate the valve such that a state of the valve is changed based on the flow target;determine that the flow of the fluid includes an air pocket;purge the air pocket from the flow of the fluid;receive an indication associated with a determined fouling of the device of the fluid distribution system based on a reduction of an efficiency of the device; andprovide a notification responsive to receiving the indication. 2. The apparatus of claim 1, wherein the flow sensor is upstream with respect to the valve. 3. The apparatus of claim 1, wherein the apparatus includes an additional sensor connected to the controller. 4. The apparatus of claim 1, wherein the flow sensor is an electromagnetic flow sensor. 5. The apparatus of claim 1, wherein the flow sensor is configured to determine the flow at a particular interval. 6. The apparatus of claim 1, wherein the flow sensor is configured to determine an average of the flow over a particular period of time. 7. The apparatus of claim 1, wherein the valve is a nonlinear valve. 8. The apparatus of claim 1, wherein the valve is a butterfly valve. 9. A method for controlling flow in a fluid distribution system, comprising: determining a threshold flow target associated with a device of a fluid distribution system;receiving a determined flow of a fluid through a conduit of the fluid distribution system, the determined flow is determined by a flow sensor, wherein the fluid is a liquid;causing an actuation of a valve of the fluid distribution system from a first state to a second state responsive to the determined flow exceeding the threshold flow target;determining that the flow of the fluid includes an air pocket;purging the air pocket from the flow of the fluid;determining a fouling of the device of the fluid distribution system based on a reduction in an efficiency associated with the device; andproviding a notification responsive to the determination. 10. The method of claim 9, wherein the determined flow exceeding the threshold flow target includes the determined flow being less than the threshold flow target, and wherein the second state is open with respect to the first state. 11. The method of claim 9, wherein the determined flow exceeding the threshold flow target includes the determined flow being greater than the threshold flow target, and wherein the second state is closed with respect to the first state. 12. The method of claim 9, wherein the threshold flow target includes a range of flows. 13. The method of claim 9, wherein the method includes determining a difference between the determined flow and the threshold flow target. 14. The method of claim 13, wherein the method includes determining the second state based on the determined difference. 15. The method of claim 9, wherein the method includes changing a state of a pump associated with the fluid distribution system responsive to the determined flow exceeding the threshold flow target. 16. A system for controlling flow in a fluid distribution system, comprising: a device of a fluid distribution system;a plurality of flow control apparatuses of a fluid distribution system, each flow control apparatus including:a respective flow sensor configured to determine a respective flow of a fluid through a respective portion of a fluid distribution system, wherein the fluid is a liquid; anda respective valve associated with the respective portion configured to control the respective flow through the respective portion; anda computing device, configured to: receive the respective flows from the plurality of flow control apparatuses;determine a flow target associated with the device of the fluid distribution system;cause a change in at least one of the plurality of flows through a respective at least one of the plurality of portions via a change of a state of a respective least one of the plurality of valves based on the determined flow target;determine that the flow of the fluid includes an air pocket;purge the air pocket from the flow of the fluid;determine a fouling of the device of the fluid distribution system based on a reduction in an efficiency associated with the device; andprovide a notification responsive to the determination. 17. The system of claim 16, wherein the device of the fluid distribution system is one of a boiler, a chiller, a cooling tower, a radiator, a fan coil unit, an air handling unit, and a fluid heater. 18. The system of claim 16, wherein the system includes a sensor connected to the computing device and not hydronically connected to the fluid distribution system.
