Abstract: An adapter cap for a fire hydrant including a hydrant actuation nut by means of which the hydrant is opened and closed by rotating the hydrant actuation nut, where the adapter cap includes a cap housing having connection means for connecting the adapter cap to the hydrant actuation nut, the cap housing having a cap actuation nut by which the adapter cap may be engaged and the cap housing including a skirt part arranged to encircle at least a part of the connection means, where a connection means centre axis of the connection means and a cap actuation nut centre axis of the cap actuation nut are arranged coaxially, where the connection means and the cap actuation nut are made from metal, and where at least a part of the skirt part is made from a polymer material, the adapter cap further includes at least one sensor arranged in the cap housing, where the at least one sensor is arranged to detect at least one operational parameter of the hydrant, and wireless communication means arranged in the cap housing for c

Abstract: Disclosed is a method for operating a valve (1), the method comprising the steps of locating an operating key system (2) at the valve (1), communicating a location of the operating key system (2) wirelessly to a central data system (3) from the operating key system (2), communicating a rotational direction to open or close the valve (1) wirelessly from the central data system (3) to the operating key system (2) based on the location, engaging operating means (5) of the valve (1) by means of an operating key (4) of the operating key system (2), rotating the operating key (4) manually towards an open or a closed position of the valve (1) while engaging the operating means (5) based on the received rotational direction to open or close the valve (1), detecting the direction in which the operating key (4) is rotated, wherein the direction of rotation is detected by means of rotation direction detection means (6) of the operating key (4), detecting if the valve (1) has reached the open or closed position, wherein

Abstract: A method and system for remote estimation of hydrant water pressure at a hydrant located at an end of a branch pipe being branched of a main pipe, the method including detecting a valve open-close status of a stop valve arranged in the branch pipe and transmitting the valve open-close status wirelessly to an external data system, detecting a hydrant open-close status of the hydrant and transmitting the hydrant open-close status wirelessly to an external data system, detecting a branch water pressure of water in the branch pipe and transmitting the branch water pressure wirelessly to the external data system, and estimating the hydrant water pressure at the hydrant based on the valve open-close status, the hydrant open-close status and the branch water pressure.
