The first turbine flow meter was invented by Reinhard Woltman in the year 1790. He came up with the design in relation to the need of studying the loss of water flow speed in the open canals. Ever since then, turbine flow meter has seen quite a lot of innovations in terms of equipment. Although, the exceptional design continues to be somewhat the favored flow meter whilst it comes to computing the water flow in major magnitude. It is known as the Woltman flow meter.
Afterward progress in the technology has resulted in the formation of eight different types of turbine flow meters. While some of the flow meters have been named after the type of water wheels on which they are based, whilst some others are named after the machinery and equipment. Normally speaking, there are varied types of Turbine Flow Meters that offers excellent function.
Far and wide preferred for their economic installation, ownership and maintenance, liquid turbine flow meters recommend repeatable measurement and high accuracy under the most challenging conditions of custody transfer applications. Specific installations take account of refined product pipelines and crude oil, mobile operations, tank farms and marketing terminals.
Highly precise measurement is attained by making use of bladed rotor which rotates at a speed relative to rate of flow. Rotor rotation is sensed by electrical pickoffs built on the meter body, thereby producing a pulsing voltage. The whole number of pulses collected over a certain period of time symbolizes the metered volume.
Turbine flow meter (better explained like an axial turbine) translates the automatic action of the turbine rotating in the fluid flow around an axis into user readable rate of stream (gpm, lpm, and so on.). The turbine should have all the flow traveling around it.
The flowing liquid imposes on the turbine blades, thereby passing on the force to the blade surface and placing the rotor in motion.
