Turbine Flow Meters: The Types and Fundamentals

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.

Facts You Weren’t Aware About Turbine Flow Meters

The Turbine flow meter or also called as axial turbine was invented by Reinhard Woltman and, it is an accurate and reliable flow meter for liquids and gases. It takes account of a somewhat magnetic multi bladed free spinning rotor, also called as impeller mounted inside at right angles to the flow. The rotor is evenhanded in the flow by the aid of 2 end supports which act for straightening the flow prior reaching the turbine. Whilst the flow reaches the turbine, the turbine starts spinning owing to the applied force by the flow.

A pick up sensor is built above the rotor. The Inductance type sensor creates a voltage pulse every time a rotor blade passes. Depending upon the kind of signal receiving the instrument; a pre amplifier may perhaps be required. The Hall Effect sensor provides square wave output every time a blade passes and has a fitted pre amplifier. Hall Effect sensor also makes less magnetic drag on the rotor and is more appropriate for the lower flow rates.

The pickup sensor creates pulses the moment the rotor blade passes; it delivers a very fast reaction time making this sort of flow meter highly suitable for the batching purposes.

The Turbine Flow Meters come with very small difference from the fabricating process. As such, they all need to be adjusted by yourself. The pulses created by the pickup sensor be a symbol of pulses per unit volume, also referred to as k factor. Every kind of Flow Meters is supplied with calibration certificates and specific k-factor.

The standard Turbine flow meters have the rotor and rotor end supports and the stainless steel body. The bearings are of Stellite or Aluminium Trioxide. Even though, the Turbine flow meters are obtainable in various other materials on requirement. The Stellite bearings provide a supreme extensive life time.

Turbine Flow Meter: Why Are They So Highly Used?

Turbine flow meters make use of a confirmed and established flow measurement technology which is used for providing extremely and remarkably reliable and accurate digital outputs. For the reason of their adaptability and flexibility, these turbine flow meters are the explanation for a wide range of gas and liquid flow sensing applications. Turbine meters are a perfect and idyllic solution at the time when compact size, high accuracy, quick response, and elevated tolerance to alarm and vibration are serious and grave needs. Turbine meter sizes vary from 3/8 inch to 4 inches. It is a tool or equipment which is used for measuring the volumetric flow of a liquid. Usually, this particular flow meter is used for measuring the flow rate from the varied number of revolutions of the control of liquefied gas, petroleum products, water, general chemical liquids, and so on.

Turbine Flow Meter is less precise than displacement and jet meters at low flow rates, although the measuring constituent or component does not occupy or sternly limit the entire path of flow. Since these meters are highly useful in various industrial applications, therefore, they must be availed from the most prominent and renowned flow meter manufacturer. And the flow meter supplier must ensure that the products which they are availing from the fabricating and manufacturing unit, fabricates it from the most fine quality raw materials.

It is the job of the flow meter supplier that they ensure that the procured flow meter is equipped with all the required utilities and features and properties. Among the properties which are highly noted in any industrial equipment are durability, extended functional life, reliability and wear and tear free. All these mentioned features and properties should be there in the flow meter, but, if these are not studded or equipped in the flow meter then it may happen that the availed product may malfunction.

 

What You Should Know About Turbine Flow Meters

The Turbine flow meter or also known as axial turbine was invented by Reinhard Woltman and, it is a reliable and accurate flow meter for gases and liquids. It comprises of a somewhat magnetic multi bladed free spinning rotor, also known as impeller mounted inside at right angles to the flow. The rotor is balanced in the flow by the help of 2 end supports that act for straightening the flow before reaching the turbine. While the flow reaches the turbine, the turbine starts spinning because of the applied force by the flow.

A pick up sensor is built up above the rotor. The Inductance type sensor generates a voltage pulse every time a rotor blade passes. As per the kind of signal receiving the instrument; a pre amplifier might be required. The Hall Effect sensor offers square wave output every time a blade passes and has a built-in pre amplifier. Hall Effect sensor also creates less magnetic drag on the rotor and is more apt for the lower flow rates.

The pickup sensor creates pulses the moment the rotor blade passes; it offers a very fast reaction time making this sort of flow meter highly appropriate for the batching applications.

The Turbine Flow Meters come with very small disparity from the fabricating procedure. As such, they all require to be adjusted individually. The pulses generated by the pickup sensor symbolize pulses per unit volume, also referred to k factor. Every kind of Flow Meters is supplied with specific k-factor and calibration certificates.

The standard Turbine flow meters have the stainless steel body and rotor end supports and the rotor. The bearings are of Aluminium Trioxide and/or Stellite. Although, the Turbine flow meters are available in various other materials on demand. The Stellite bearings offer a supreme extensive life time.

Turbine Flow Meters: The Basics And Types

The first turbine flow meter was made-up by Reinhard Woltman in the year 1790. He came up with the design in response to a requirement of studying loss of water flow speed in open canals. Ever since then, the turbine flow meter has seen several innovations in terms of machinery. Though, the unique design continues to be more or less and is still the favored flow meter whilst it comes to calculating the flow of water in major quantities. It is called as the Woltman flow meter.

Later progress in the technology has resulted in the creation of eight different kinds of turbine flow meters. Whilst some of the flow meters have been named after the kind of water wheels on which they are based, while some others are named after the equipment and machinery. Generally speaking, there are varied kinds of Turbine Flow Meters, at present, in use which provide excellent function.
