give the details of water level measuring sensors?

You really need to be talking to the manufacturers of the equipment in question. They will know more about what their meters will do than anyone else.

The question is:  What should I set on the sub-scale of my altimeter so that the instrument would indicate my elevation if I were on the ground at your station?\n\nANSWER:  QNH

Floods are measured using electronic sensors & gauges in the rivers' banks & on the sides of bridges. Sometimes they still use the wire from the bridge & the oldest trick, the ruler method.\n\nThe USGS has them located along major creeks, streams, & rivers.\n\nThey are especially important where roadways cross running water or are nearby housing developments.

stick it in a tank of water then measure the water displaced.archemedes law

Try this site for high and low tide.  It's the best I can do without knowing the exact location in the Wesminter area you need this data for.\n\nhttp://tidesandcurrents.noaa.gov/tides06/tab2wc1a.html#122

I don't think you will find a circuit diagram for a digital water (fluid) meter so easily. But let's analyze what you need to build one:\n1) A flow sensor (a "turbine" wheel that outputs pulses), tricky to build a reliable one by yourself....\n2) A counter,  see http://www.kpsec.freeuk.com/counting.htm\n3) A display, and its driver.\nUnless you want to buy a complete electronic flow meter, like  http://www.rittenhouse.ca/asp/product.asp?PG=1553\nor more "professional",\nhttp://www.flowmeters.com/products/index.cfm?task=cat_prod_page&master=yes&master_cat_id=29&cat=yes&cat_id=163#29_163

You could measure the volume of fuel in the tank by weighing the tank accurately as it is filled with fuel. The weight of a gallon of fuel is known accurately. Home heating oil tanks utilize crude floats to measure the height of the oil level in the tank, but more sophisticated level indicators are available for industrial uses.\nSearch http://www.ThomasNet.com for that application.\nhttp://www.thomasnet.com/nsearch.html?cov=NA&which=prod&what=tank+level+sensors&navsec=search&heading=96118542

Put it in a graduated cylinder, record the water level, drop the rock in, and note the new water level. Subtract.\n\nYay science.

Just take a look at NOAA's site.  Here's the link: http://www.fuzeqna.com/noaa.answers/consumer/kbdetail.asp?kbid=556

Use a water level:  \nTake a long piece of hosepipe, put a short length of clear tube in each end.  \nFill with water and with a friend lay the pipe along the ground with the open ends (with the clear tube pointing upwards).\nThe water in the clear tubes at each end will be at the same height.

you have your water temperature at between 37degrees and 39degrees buy yourself a thermometre to place in the water to check before you get in ok

Supervisory Control and Data Acquisition.\n\nThe system provides reliable data collection and continuous real-time control in a user-friendly environment. In Layman’s terms, the system is designed to supervise the flow of sewer water through the pump stations, and to perform certain functions, such as shutting off or turning on certain pumps, etc. The system consist of telemetric stations mounted on the individual pump and control stations and water tanks, water treatment and cleaning plants, and a dispatching center made up of one or more computers installed at the central dispatching facilities. Data transmission takes place using portable means, typically radio data networks, GSM or phone.
