The first turbine Reinhard Woltman invented in 1790. The idea came in response to a test required, the loss of water in open channels. Since then, Turbine has seen many innovations in technology. However, the original design is more or less, and still preferred the meter, the meter when the flow of water in large quantity. And: "If the meter Woltman known.
Subsequent developmentsturbine technology, eight of the flow. While some of the flow is a kind of water wheels, which are listed on some of the names of art. Overall, the various types of turbine flowmeters that are currently used:
Flowmeter
Pelton wheel
use based on the original Pelton, Pelton turbines for river water has been linked to external rotationIf water or liquid is equal to the wheel, the wheel starts to spin. The Pelton turbine flowmeter is a function similar to a compact chassis and is used to measure the flow rate of the fluid of low viscosity at this slow.
Paddle wheel
Blade back into the building water wheel. These types of tools to measure trees perpendicular to the direction of flow. A wave on a small buckettransforms the flow of waves of movement. The fan speed is proportional to fluid velocity. Flow Blade is the most efficient flow at low speed.
Propeller
propeller flow meter according to the principle of the turbine propellers, the base is used to generate hydropower. Nagler was invented in 1916 by Forrest, one of the turbine blades of the propeller, and the clock 3.00 bis 06.00 hours was a wooden boat propeller. TheThe blades are fixed and rotate around a central axis. Flowmeter propeller is a great benefit in the form of letters or less, which makes them immune to damage from debris. They are also very inexpensive and require no power adapter for flow measurement.
Woltman
Woltman invented the first turbine flow meters and is still widely used in applications of municipal and industrial water use, measure the flow of large quantities of water.These tools, which are very precise measurements, is roughly aligned with the axis line direction of flow.
Single Jet
Jet is a single blade assembly positioned directly in the path of a stream or jet of a tube. The jet stream, or use a diaphragm. The counters are mainly used for accounting purposes, residential activity and commercial buildings used in the water.
Multi-Jet
Based on the principle that a jet-meter Multi-JetFlowmeter in the water holes in the blade of several rotating a central shaft. water meters with multiple jets are used for the purposes of water supply accounting residential and commercial buildings.
Logo
The instrument is a cross between a turbine and a regular flow meters. It is both a turbine and a component of displacement. If broadband, measured by the speed of the turbine. At low flowOn the other hand, using components of displacement. These types of hybrids are widely used flow meters to measure residential buildings, the different streams of the day and night.
Axial
an axial flow or turbine rotor rotates about the axis of the flow, hence the name. These devices primarily to measure the flow of petroleum products, liquid and gas. Depending on the material they are used, axialUnits of different sizes for liquids and gases.
