I'm mildly surprised that Titanic didn't have a Heulsmeyer device -
the radio was up-to-date and little money seems to have been spared
elsewhere.

Heulsmeyer didn't manage to get anyone interested in his device, so it
never went into production and so would not have been available.

Marconi provided the radio equipment for Titanic and they did not take
much interest in radio location until the 1920s. Even then it was not
until SS Normandie entered service in 1935 that any ship had radio location.
