A watertight electrical compartment for use in an irrigation device can include a compartment body with a chamber, a sealing section mounted with one or more sealing rings, and external threads. A sealing cap 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 and can have internal threads to be screwed onto the external threads of the compartment body. 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, and an outer wall surface having external threads and a sealing section, the sealing section located closer to the open end of the chamber than the external threads;at least one sealing ring having a diameter configured for mounting on 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 sealing ring when the sealing ring is mounted on the sealing section; anda cap retainer having internal threads configured to threadedly mate with the external 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 cap has a non-threaded inner wall. 3. The watertight electrical compartment of claim 1, wherein an inner wall of the cap retainer further comprises a non-threaded portion further away from the first end of the cap retainer than the inner threads. 4. 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. 5. 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 internal threads of the cap retainer mates with the external threads of the compartment body. 6. The watertight electrical compartment of claim 1, wherein a wall of the cap further comprises at least one notch at the open end. 7. 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. 8. The watertight electrical compartment of claim 1, further comprising a plurality of sealing rings positioned between the cap and the outer wall surface of the electrical compartment body. 9. The watertight electrical compartment of claim 1, wherein the chamber of the compartment body is configured to house at least one battery. 10. The watertight electrical compartment of claim 9, wherein the chamber comprises battery contacts. 11. The watertight electrical compartment of claim 9, wherein the chamber comprises a DIP switch. 12. The watertight electrical compartment of claim 9, wherein the chamber comprises flash programming pads. 13. The watertight electrical compartment of claim 1, wherein the compartment is configured to be electrically coupled to a flow sensor. 14. The watertight electrical compartment of claim 1, wherein the sealing ring is resilient.
