Basic Knowledge on Flow Meters

Published on: 17 May 2019 Last Updated on: 03 December 2021

In ancient history, resources are abundant, but with the fast-growing population of the earliest civilization, it’s either compromise or face the wrath of bloody conquest. Flow meters are widely used equipment that can create miracles in the 21st Century. To avoid bloodshed, the earliest civilization were civilized enough to meet an agreement regarding everything, and this would include water resources. Flow meters can make things easier for you. It can help you to achieve your goals.

The wisest engineers of their time created a way to distribute the water from a nearby river equitably. They aim to justifiably distribute enough water to each city with accordance to their population’s needs. Thus, given only the flow of the river and with the help of mathematics, they strategically developed a way to measure the amount of distribution of water in the aqueducts of each city.

The answer to their problem is flow measurement or flow meter. Up to this day, this system and the works are still applicable to our modern day plumbing and has helped engineers throughout the globe in flow measurement challenges.

Essential Factors To Know About Flow Meters

There are several essential factors that you need to consider about the flow meters while you want to get the things done in the correct order.

Flow Measurement Importance:

Typically, in a household setting, this is very much needed to regulate gas or water flow through installation or fixing. In layman’s term, it helps your plumber troubleshoot with your clogged sink or toilet. But for mass production factories, engineers like chemical, mechanical and application engineers use this to understand what went wrong, how to maximize production, if the process is accurate. Flow measurement is essential to have a smooth-flowing operation of their products.

What is Flow Meter?

The most basic stuff you need to know about flow measurement is flow meter. Basically, this is an instrument that measures volumetric flow (Q) denoted in a unit of cubic meters per second, linear or nonlinear mass indicated by kilograms, pounds, etc.. A typical flow meter design would include parts like paddlewheel sensor, locknut, built-in temperature sensor, and pipe tee.

Flow Meter Appropriation:

There are all sorts of type of flow meters available in the market, but you can’t just buy one and try it on the operation. Unless you know what you are doing and you were told to buy so, other than that, you won’t have a problem. Though having a lot of options for this instrument is liberating, this is also a disadvantage for personnel. Personnel should know how a particular device works to avoid miscalculations. Staff should also be knowledgeable for recalibration if needed. Staff should also be prepared for casual maintenance. There’s a lot more to consider like fixing the instrument, etc. The flow meter should be chosen wisely to reduce expenses.

Guidelines When Choosing a Flow Meter:

What fluid do you intend to measure?
How viscous is the liquid you intend to measure?
Do you also want a rate measurement?
Which do you prefer a primary local display on your instrument or electronic signal output?
What are the limitations of your chosen instrument based on flow rate, temperature, and pressure?
Will the liquid not dissolve your instrument?

Common Types of Flow Meter:

Ultrasonic Flow Meter:

If you intend in using this instrument is waste waters or other dirty fluids; ultrasonic flow meter is more applicable in this kind of areas. The Doppler Effect or the frequency shift is necessary during operations to harness suspended particles and gas bubbles at large.

Variable Area Flow Meter:

Also called Rotameters, this flow meter is a low cost and a simple instrument efficient for liquid and gas flow measurement. It also displays a wide rangeability of flow measurement, low-pressure drop, and linear output.

Vortex Meters:

If you want an instrument that quickly detects sudden fluctuations in process conditions or turbine meters, this flow meter is what you are looking for. Vortex meter possesses a low sensitivity quality to variation in the operation. This type also is available in many sizes and doesn’t sting in the wallet; that is why many users prefer it.

Spring and Piston Flow Meter:

This type somewhat looks likes a rotameters because of the tapered tube, used in both instruments. It must be situated in the no-flow position through a calibrated spring. This is more preferred than rotameters because it is user-friendly and economically friendly. It can also transmit electrical signals, and the design is much simpler.

Paddlewheel Sensors:

It is the most popular flow meter for water and water-like substances, but it is essential to check the compatibility of the fluid to be measured and the sensor. The rotor of this instrument is situated perpendicularly to the flow; thus, a better opportunity for personnel to avoid contact in case of toxic fluid is measured.

Turbine Flow Meter:

This instrument gives an accurate reading for the flow measurement, providing only a 0.5 probability of error. The Turbine Flow meter looks like a paddlewheel sensor with the rotor perpendicularly situated to the flow and is hanged in the fluid stream. Due to its accuracy, it is highly recommendable if the liquid to be measured is made of clean and viscous liquid.

5 Cool Antique Cotton Harvester

Cotton plants have been an integral part of the United States and American history since the first days of colonization. Along with tobacco and the gold and silver mines of South America, cotton was one of the most valuable exports which created an immediate demand in Europe, resulting in many investors funding some of the first communities to profit from cotton production. Cotton is a labor-intensive difficult crop to grow and harvest, unfortunately, slave labor was sued for much of the hardest aspects of the job. With that said, people are inclined to always “build a better mousetrap” and also have tried more efficient means of harvesting cotton. Although modern technology has made for much more efficient cotton machinery with an expected use for industrial farming, the simplicity and beauty of antique equipment can make for a fun hobby to restore and use on a smaller scale than what is required of commercial farms. Some have been designed as an attachment to be used with a regular tractor, essentially running the tractor in reverse with the large wheels to the front instead of the rear, others were made as independent designs specific for the single use of picking cotton and transporting it back to the barn to be cleaned by a cotton gin and baled as a separate process. Over the years, there have been some exceptionally cool ideas about how to pick cotton without the extensive labor required when people have to harvest by hand. 1820's: Trained Monkeys Nobody can argue how cool an idea it was when a Louisiana farmer had the idea in 1820 to purchase a group of money and train them to pick cotton. This almost sounds like a joke from a comedy movie, but the guy actually thought it might work. Spoiler alert, it didn't. He was able to teach them to pick cotton while in captivity, but when he released them into the fields to actually conduct the harvest, they quickly became distracted and ran off into the surrounding woods. Okay, the proof is in the pudding and maybe that wasn't a “great” idea, but such idiocy certainly brings a few giggles to nearly everyone when they hear the story. Patent Number 7,631, Subclass 48 Invented in 1850 by Samuel S. Rembert and Jedediah Prescott of Memphis, TN., the first cotton picking machine used cylinders and disks to pick cotton. The interesting aspect of the invention was it's being designed to add more units capable of harvesting more than one row at a time, a concept still used by modern harvesters. It didn't work well in terms of reliability because it required the operator to constantly stop and clean off the cotton oils as they jammed up the operating mechanisms, but it did prove such a machine was possible but needed some further development and improvement. 1930's: John Daniel Rust Rust invented one of the first usable cotton pickers in 1933, which didn't become commercially popular until 1938. It attached to the rear of a tractor and picked cotton without stripping it. Pictures show the tractor driver often holding the steering wheel to maintain a straight line while looking over their shoulder to evaluate how the harvest was proceeding. This was the machine that made mechanical cotton pickers an integral aspect of cotton farms, as they could produce as much cotton in an hour as had previously been expected after a day's worth of labor. The patent was sold in the 1940s and used by different companies before becoming an outdated machine, even though some of the most basic concepts it used are still part of modern cotton pickers, with a few upgrades and improvements to details of the harvest process. 1940's International Harvester Model 114A The I.H. Model 114A was one of the first cotton picking specific machines, and set a new standard for cotton farmers when it came out in 1943. The problem with previous mechanical harvesting was it didn't always clean the cotton efficiently enough to go straight to the cotton gin for separation. The 114A resolved that problem and reliably picked cotton while removing unopened bolls and other debris which would clog a gin. By doing so, the amount of labor required during a cotton harvest was immensely lowered while increasing production rates. With a growing demand for cotton worldwide both as a fabric and for other uses such as in cooking oil or rubber products, such an invention had become an absolute necessity toward a farm's continued success in the cotton industry. 1950 I.H. M120 Cotton Picker The I.H. M120 basically added a cotton picker to a tractor in a means which would turn the tractor into a specialized piece of machinery used only to pick cotton. It essentially turned the tractor around to drive with the large wheels in the front behind the spindles which harvested cotton one row at a time. The steering wheel and seat were moved to face what is generally considered the rear of the tractor, and the basket was mounted over the engine hood. Although modern cotton pickers operate much the same way with rear-wheel steering, they do more than just picking the cotton but also strip and bale the crop. It's interesting to see how that design began and how it has evolved over time.
