Staffs & Worcs bywash flow/level meters?

[jonesthenuke]

A number of locks on the S&W have semicircular housings in the bywash. I assume these were for monitoring the bywash flow?

 

Does anyone have information of what was in these housings and what they did? If they measured the flow, where was the information reported to and how was this done?

 

The picture shows the one in our garden. It is empty. There are some indications that there was a brick weir in this p[art of the bywash, but this has largely gone now.

 

Thanks in advance.

Looks like SCADA to me

Yes but I suspect 50 years old or more, so not SCADA in anything like current technology.

Probably a clockwork pen recorder, similar to those used in weather stations, and someone periodically replaced the chart and wound the mechanism up.
