Using electronic water meters on Shabbos
2 months ago I posted about this and various people suggested some possible halachic justifications. In today's Yated Neeman there was not 1 not 2 but 3 separate "Kol Koreh's" against using ANY kind of electronic water meter. They write in the name of various gedolim (see below) against using heterim based on safek pesik reisha or grama as they are דימויים מפופקפקים מאד. The only electronic water meter that can be used is one where the electronic component can be completely turned off for Shabbos and it will mechanically measure the water on Shabbos. This approach may work in Israel where the Charedim are a big enough population for the water carriers to accommodate them. However, this will not work in chu"l even in a place like NYC, kal v'achomer in a city with a small religious population. The poskim will need to deal with the issues of electronics on Shabbos and come up with a position that people can deal with or we will need to become Amish.
