A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

1. A watertight electrical compartment of an irrigation device, comprising: an electrical compartment body comprising a chamber with an open end, threads, and a sealing section, the sealing section located closer to the open end of the chamber than the threads;at least one sealing ring having a diameter configured for mating with the sealing section;a cap having an open end, a closed end, and an internal diameter configured to have a sliding fit with the sealing section and an interference fit with the at least one sealing ring when the compartment is assembled; anda cap retainer having threads configured to threadedly mate with the threads of the compartment body, the cap retainer further having first and second ends, the cap retainer configured to receive at least a portion of the cap through the first end. 2. The watertight electrical compartment of claim 1, wherein the at least one sealing ring is configured to be mounted in at least one groove. 3. The watertight electrical compartment of claim 2, wherein the at least one groove is located on an inner wall of the cap or on the sealing section of the compartment body. 4. The watertight electrical compartment of claim 1, wherein the compartment body comprises a channel extending further away from the open end than the sealing section along a length of the compartment body, the threads of the compartment body located on a radially inwardly facing inner wall of the channel, and wherein the threads of the cap retainer comprise external threads. 5. The watertight electrical compartment of claim 4, wherein an inner wall of the cap retainer is smooth. 6. The watertight electrical compartment of claim 1, wherein the cap has a reduced outer diameter on its closed end and the cap retainer has a reduced inner diameter on its second end, the reduced inner diameter of the cap retainer configured to slidably accommodate the reduced outer diameter of the cap. 7. The watertight electrical compartment of claim 1, wherein the cap retainer has a shoulder at its second end having an internal diameter smaller than an outer diameter of the cap, the shoulder configured to keep the cap engaged with the sealing section when the threads of the cap retainer mate with the threads of the compartment body. 8. The watertight electrical compartment of claim 1, wherein a wall of the cap further comprises at least one notch at the open end. 9. The watertight electrical compartment of claim 1, wherein the sealing section comprises at least one groove configured to receive the at least one sealing ring. 10. The watertight electrical compartment of claim 1, further comprising a plurality of sealing rings positioned between the cap and the sealing section of the electrical compartment body. 11. The watertight electrical compartment of claim 1, wherein the chamber of the compartment body is configured to house at least one battery. 12. The watertight electrical compartment of claim 11, wherein the chamber comprises battery contacts. 13. The watertight electrical compartment of claim 11, wherein the chamber comprises a DIP switch. 14. The watertight electrical compartment of claim 11, wherein the chamber comprises flash programming pads. 15. The watertight electrical compartment of claim 1, wherein the compartment is configured to be electrically coupled to a flow sensor. 16. The watertight electrical compartment of claim 1, wherein the at least one sealing ring is resilient.
