Types Of Liquid Flow Meters Used Industrially And Their Applications

Gauging the flow of liquids is not a piece of cake. A liquid flow metering is very crucial in any industry. Most firms use a liquid flow meter as a device to gauge the flow of liquids. In the industry, you find many liquid devices used to ensure there is accuracy in the projects. Below are the types of fluid flow sensors and their uses. Relax and get more details from this guide.

Coriolis Meter

These devices are accurate mass meters that measure the mass rate of flow directly, unlike volumetric flow. This meter is linear without the need to adjust for variations in liquid traits. That is since mass does not change. There is also no need to compensate for changing heat and force conditions. Coriolis meter measures liquids whose viscosity varies with speed at a given heat and force.

This meter comes in various versions. A trendy unit has a u-shaped flow tube enclosed in a sensor linked to an electric unit.
You can fix the sensing unit directly into the process. Generally, you can locate the electronics unit up to 500 feet from the sensor.
The u-shaped flow tube is vibrated its natural frequency by a magnetic tool found at the end of the pipe. Usually, the vibration is similar to that of a tuning fork and covers less than 0.1mm. It completes a full cycle of about 80 times per second.

Open Channel Meters

https://www.chinaultrasound.com/wp-content/uploads/2019/11/Picture1.pngAre aware that an open channel, as the name suggests, is any conduit in which liquids flow with a free surface. Those conduits include streams, canals, rivers, tunnels, to mention but a few. Depth-based methods are the most commonly used ways of monitoring open channel flows. These ways presume that the flow rate can be known from gauging water depth. Weirs and flumes are the most widely used tools for estimating open channel flows.

Typically, weirs work on the law that states that an obstruction in a channel leads to water backing up, creating a high level behind the block. They have vertical plates with sharp crests. The head is the work of speed, hence the flow rate in a device.
Weirs are divided into various classes based on the shape of the notch. The top of the plate is either notched or straight. Some of the designs that come with this meter are trapezoidal, rectangular, and v-notch.

Electromagnetic Meters

https://5.imimg.com/data5/JR/BT/MY-11895202/electromagnetic-flow-meter-500x500.jpgThese meters can handle most liquids and slurries, as long as the material being metered is electrically conductive. The force drop across the meter is the same since there are no moving parts or obstructs to the flow. You can attach the voltmeter directly to the flow tube or fix it remotely and link it with a shielded cable.

The amount of voltage created is the same as that of the flow rate. The liquid serves as the conductor, while the magnetic field is created y energized coils outside the flow pipe. The two plates fixed in the tube wall detect the voltage.

One of the significant benefits of this device is that it can gauge the flow of corrosive liquids and slurries. It can also measure forward and reverse flow with equal accuracy. But these devices have high power consumption since excitation happens only half the time in the unit.

Ultrasonic Meters

You can fix two transducers in a case attached to one side of the tube. An alarm of known frequency is sent to the liquid. Any discontinuity, bubbles, or solids in the fluid can lead to a reflected pulse. 

Orifice Meters

These are the most famous type of liquid meters in the industry. Most of the orifices are concentric designs, but you can also find eccentric, segmental, and conical types. The orifice plate is fixed in the tube in two flanges. This device cramps the flow of liquid to give a gulf force across the plate. You can force taps on either side of the plate to tell the variations. One of the significant pros of using this meter is that it has no moving parts and is always affordable.
A segmental orifice gauges the flow of liquids that have solids. It has a simple design, and the force drop in a unit is only about half that of conventional orifices. Its unit can flow at low numbers and keep the desired square root link.

Final Words

The ability to get accurate flow gauging is very critical in any operation. That is because it tube’s tube’s tube’s tubes can determine wet get a loss or profit in your project. When it comes to achieving accurate flow, liquid flow metering is very vital. It would help if you got the best liquid flow meter to help you make the desired output. That will help you to save time and money in the future.
