Pvc Sensor
A Digital Water Flow Meter
The digital water flow meter consists of a turbo prop sensor which is attached to a handle that is expandable and has a digital readout display. The Global Water Flow Probe is a very accurate water flow instrument that measures the flow in open channels as well as in partially filled pipes.
The digital water flow meter has true velocity averaging and can measure flows in a very accurate manner and is used for measuring flows in rivers and streams as well as monitoring velocity in ditches as well as canals. The digital flow meter also has many features to it including easy flow monitoring, digital display in ft/second or meters per second, does not weigh much and is reliable as well as rugged and is used by water professionals all across the world.
Debris Shedding Turbo-Props and Telescoping Handle
This digital water flow meter also has debris shedding turbo-prop and a telescoping handle with staff gauge and can display instantaneously true average velocity and also has a rain-proof digital computer read out. It is most useful for measuring flows in streams, rivers, canals, storm waters, wastewaters and industrial process waters.
To operate this digital flow meter, its flow probe incorporates the unique turbo-prop propeller sensor which makes it possible for positive displacement techniques to sense velocity and is designed to shed debris and has ample protection inside the two inch diameter housing. One can place the probe housing directly on the bottom of the pipes or streambeds in order to measure low flows down to two inch depths and the flow motor propeller turns feely on the shaft without mechanical interconnections and so has almost no friction.
In addition, the flow probe handle is able to telescope from three feet to six feet in height or five feet to fifteen feet and is made of anodized aluminum for its low weight as well as durability and can be extended up to twenty-five feet in length with the help of Pvc Pipe and extension cables, which allow sewer flow measurements from the level of the street and measuring of stream flows from the bridge. Attached to the lower section of the digital water flow meter is a three feet Mylar coated staff gauge which is graduated in hundredths of a foot and centimeters and this helps in instant water depth measurements as well as accurate positioning of the propeller.

Tales of the bizarre. My outdoor motion sensing security light is now working after not working for 6 months?
I wired this thing last summer and it worked fine all summer until fall when it started raining.
I did a fair job of sealing the conduit with Teflon Tape and pvc glue (the purple stuff) and so I don't think its a water issue.
But the damned thing stopped working last November and I thought the wiring had come undone, but apparently that's fine because now the light is working again.
When it wasnt working, it could be turned on for TEST mode, but the Motion Sensor never activated the light on. Now all of a sudden it works fine.
Any ideas??
No use worrying about why it failed, since it now works. There are any number of reasons why it may have failed, from a loose wiring connection, or being left in the test position, even burnt out Light Bulbs.
I would say replace it anyway, since they aren't that expensive and you have some question about the reliability of the fixture.
good luck with it.
