Water flow measurement devices.

The differential pressure flow meter is based on the bernoulli equation where the pressure drop and the further measured signal is a function of the square flow speed. Reading this differential pressure and applying bernoulli s equation will allow for the calculation of the fluid velocity. Streamflow cannot be measured directly say by plunging an instrument into a river. Hydro flow tech is a leading manufacturer of water flow and level measuring devices.

Dp ρ v2 2 1. Among the major types of measurement devices used in surface water open channels and or closed conduits are. The pitot tube 3. Water flow measuring devices.

27aivpd8626l1zj hydro flow tech engineers is an iso 9001 2015 company based in nashik maharashtra. Orifice plate or orifice meter 4. This device is a section of tube that measures the pressure at the tip and the pressure at the side of the tube. Because they are used for domestic water measurement piston meters also known as rotary piston or semi positive displacement meters are the most common flow measurement devices in the uk and are used for almost all meter sizes up to and including 40 mm 1 1 2 in.

A venturimeter is a device meant for measuring the quantity of a liquid flowing through a pipe. In a differential pressure drop device the flow is calculated by measuring the pressure drop over an obstructions inserted in the flow. These products are designed and engineered as per the set quality standards. Ultrasonic open channel flow meter.

Piezometer digital water level recorder. Instead it must be calculated in a process known as stream gaging. Streamflow is a measurement of the amount of water flowing through a stream or river over a fixed period of time. In the simplest method a current meter turns with the flow of the river or stream.

The following points highlight the five main types of devices for measuring of flow in pipes. The piston meter operates on the principle of a piston rotating within a chamber of known volume. The pitot tube is a simple device that allows for the measurement of the flow pressure in a moving fluid. Weirs flumes current meters orifices propeller meters strain gage.

Dae water meter as series by dae 32 99 32 99. The depth of the water is also measured at each point. The current meter is used to measure water velocity at predetermined points subsections along a marked line suspended cableway or bridge across a river or stream. There are several types of flow measurement devices currently in use across the united states by private local state and federal agencies.
