摘要

Disclosed is an adapter cap (1) for a fire hydrant (2) comprising a hydrant actuation nut (3) by means of which the hydrant (2) is opened and closed by rotating the hydrant actuation nut (3). The adapter cap (1) comprises a cap housing (4) comprising connection means (5) for connecting the adapter cap (1) to the hydrant actuation nut 5 (3), the cap housing (4) comprising a cap actuation nut (6) by which the adapter cap (1) may be engaged and the cap housing (4) comprising a skirt part (24) arranged to encircle at least a part of the connection means (5), wherein a connection means centre axis (8) of the connection means (5) and a cap actuation nut centre axis (9) of the cap actuation nut (6) are arranged coaxially, wherein the connection means (5) and the cap 10 actuation nut (6) are made from metal, and wherein at least a part of the skirt part (24) is made from a polymer material. The adapter cap (1) further comprises at least one sensor (10) arranged in the cap housing (4), wherein the at least one sensor (10) is arranged to detect at least one operational parameter of the hydrant (2), and wireless communication means (11) arranged in the cap housing (4) for communicating the at 15 least one operational parameter wirelessly to an external data system (12). An adapter cap kit (23), a fire hydrant (2), a method for remote monitoring of at least one operational parameter of a fire hydrant (2) is also disclosed.
