How to Measure Liquid Flow Accurately With Flowmeters
How to Measure Liquid Flow Accurately With the Help of Flowmeters
While transferring a certain fluid from one medium to another the measurements are required to be extremely accurate. There exist innumerable tools for measurement of the flow of fluids through pipes. These tools usually operate on different principles with help in monitoring the flow of the liquid, and each of these retain some pros and cons while being compared to others.
Therefore when you ask how to measure liquid flow accurately, the possible answer could be flowmeters. In order to determine the rate of streaming and the quantity of transfer of a fluid, the usage of the flowmeters is profound. There exist several kinds of these devices. Some of the flowmeters and the benefits of their usage have been enumerated below.
Different aspects of the flow of a liquid can be measured with the help of a range of flowmeters. Thus, some appropriate answers on how to measure liquid flow accurately have been given below:
Measurement of density and viscosity
This flowmeter employs the Coriolis effects, where the tube connected to the meter vibrates cross-wise to twist the fluid inside so that it can measure the density and the amount of liquid flow. Irrespective of the kind of fluid being measured, the device provides you with the accurate measurement.
The Coriolis meter employs its oscillating motion in order to produce vibration inside the tube through which the liquid is flowing. The temperature of the outer wall, the pace of the liquid flow, and the liquid density are measured by the meter with high accuracy.
Some of the meters can also measure the viscosity of the fluid. What makes the Coriolis meters stand ahead of the similar types is its ability to measure direct mass. Since the measurement of mass is not subjected to changes in density, pressure, viscosity, and temperature; therefore, it can even measure the slurries and liquids.
Though being one of the most expensive measurement devices, this meter is reliable, accurate and hence has found its wide usage in sanitary applications. Therefore, this is the ultimate device if your area of application requires high accuracy.
- Measurement of temperature
Similar to Coriolis meters which measure the mass of a liquid passing through it, the thermal meters also work on different principles. The thermal property of a liquid is used by the thermal meters to determine the flow of the liquid in bulk.
Since there are numerous devices that fall under this principle, the advantages and the drawbacks of this device are hard to be presumed. While some of the devices measure the dispersal of the fluid on application of heat, the others may determine the disparity between the stream and the heated component.
Among the advantages, the low purchase cost of the device and the capacity to assess even the low-density fluid is worth to be mentioned. However, the accuracy of the measurement may differ according to the model and the manufacturer.
- Measurement of liquid streaming
As the Petroleum, water, chemicals, and hydrocarbons pass through the pipe, they are measured by the Turbine meters with extreme efficacy. A turbine is placed in the streaming fluid so that it can be pushed by the streaming fluid and the blade can be set to spin. The speed, when reaches its steadiness, is proportionate to the velocity of the fluid.
A higher flow rate and lesser pressure loss can be achieved, as the flow direction of the medium is straight and not twisted when compared to other meters. In order to make the liquid free from any kind of larger solid particles, a strainer is fixed on the front side of the device.
This meter is often favored due to its ownership, reasonable cost of installation, and maintenance. Even under the challenging conditions, these devices can provide you with the accurate and repeated measurement.
- Measurement of Volumetric flow rate
The principle of measuring the volumetric flow is employed by this device. This meter batches, mixes, and measures any kind of fluids including hydrocarbons, chemicals, water and few more liquids. The ceiling surfaces, plugs and bearings of the flowmeter may incur damage due to the abrasiveness or impurity in the liquid.
The filter attached to the meter is likely to remove all the impurities, bubbles and debris more consistently as the bubbles would result in comprising with the effectiveness of the device. The problem of the bubbles in the liquid may be taken care of with the usage of an eliminator.
- Measurement of the average velocity of the emitted ultrasound beam
The function of an ultrasonic wave measurement device can be familiar to you if you are familiar with the operation of an ultrasound generator. This kind of device can be segregated into two categories:
- The measuring tool that diffuses the ultrasonic wave into streaming liquid and receives the wave reflected to measure the flow.
- The device that uses two ultrasonic converters of energy that transmit ultrasonic vibration forward and backward between the two and thus measures the rate of streaming.
This type of measuring tool is usually and the most popularly used in sanitary applications, as it can be fixed to the outer side of the tube without being inserted into it. As compared to any other devices it can reduce the certainty of any leakage and can be removed or replaced at ease without making any damage to the pipe.
Even in the pipes where there is a considerable swirl in the fluid this technology can provide you with the accurate measurement. This kind of device has found its application in various industries. While answering the question on how to measure liquid flow accurately, it can be said that this device is a non-invasive and great solution.
If your business requires measuring the accurate rate of streaming of a fluid, the above-mentioned flowmeters and their exceptional services can be a savior to your enterprise. Finding out the right device for your job is important; hence, pick up the best tools for your business.
