Mystery Location

Recommended Posts

Yes, 2 of them, one top, one bottom, angled so as to give a "range" for something approaching.

There are three sensors in my photo,

the middle one is just in view partially hidden by vegetation.

Interesting.

Why would you need 3 to detect the speed and position of a moving object when 2 can easily do the job?

It has another purpose doesn't it?

They look like ultrasonic transducers, the middle one is not mounted equidistant from the outer two.

My guess would be a device for counting the numbers of people of different heights passing a point. Adults, children and leprechauns ?

Not people then, animals

It looks quite rural

The pieces of wood either side are obviously intended to protect this device

Quick guess at the place

NO,

I think it must be a Soviet bugging device left over from the cold war <_<

There is a Red in the bed, a snake in the grass B)

..and remember, careless talk costs lives! :o

I posted this yesterday (the post disappeared)

Does it control an automated car park barrier. To stop it closing onto your car (or head)

Could do I suppose, but even the top sensor appears to be quite low down.

Low down in relation to what ?

I can't see where the ground is.

Anyone else ready to ask for a slightly wider view ? See if it gives us any clues.

Yes we need a wider view.

The sensors do not appear to be that far apart, they are fastened to a loose stone wall (so presumably not too high) and they are below the level that plants have grown to, again indicating not a fantastic height.

A wider view may give us a better clue though.

Member 'hilldweller' made a post commenting that the sensor's

could be for measuring/monitoring water hight,

his post went for a walk,

along with a few more.

The sensor's do monitor water levels,

and they do so for a very specific reason.

What's the reason and where abouts are they?

Must be on the canal.

The only reason I can think of for monitoring "specific" water levels. IE three specific levels as opposed to the general level, would be at a (probably automated) lock gate on the canal.

Just thought of another reason to have them on a canal.

Warnings of:

Middle and top sensor ---- Upper and lower limits of optimum water level

Bottom sensor ---- critical level below which the system won't function.

Anywhere close ?

All the locks on the Tinsley flight are manually operated,

the nearest electrically operated lock on the S&S.Y.N. is at Eastwood, Rotherham.

The photo was taken very near to our Town center.

It was a good guess though vox.

Could they be something to do with the automated sieve "thingies" that are fastened where rivers/culverts start to go undergrand. I seem to remember something similar where the River Porter goes into a culvert to join the Sheaf in the "Megatron" under the Midland Station. I think the highest sensor would completely withdraw the motorised grating if the level was high enough and the grating blocked with debris.

Good enough for me HD,

I think there are only two automated 'trash screens'

the one you mention on the River Porter next to Midland Station,

my photo was taken on the River Sheaf along side of Queens Rd,

just upstream of where the river disappears underground on it's journey towards Midland Station.

When I last looked at the set-up by the Midland Station the water level switches seemed to be conventional electronic level gauge rods mounted inside inverted bells to shield them from moving debris. This was many moons ago when my mobility was such that I could wander about noticeing such things. At that time the machinery was newly installed. Perhaps the wall mounted gauges are a replacement or as a "belt and braces" addition. What a sad thing that I can remember technical details from about 20 years ago.

There may be more water level sensors near to or on the bridge at Queens Road,

the view is very restricted by trees and walls.

the ones in my photo are about 100 yards upstream of the bridge/culvert,

set at a higher level as they are just top side of a sill (if that's the right term) on the river,

so perhaps they contribute to the four minute warning.

Back in January 2009 Steve posted a mystery hole full of water

Now I have just seen another mystery hole full of water

Where's this

Given the state of Sheffield's roads after the damage caused by the recent very long, cold, icy winter and the lack of the ability of the Council to repair them then a local "Mystery hole full of water" could be just about anywhere! :o lol

Where's this

I worked across the road from the building in background (L/H side)

that was back in 1974, we manufactured aluminium kilns for curing wood.
