8000XHT/XLT: Best Flow Rate Measurement Instrument


Flow measurement technologies allow different industrial applications to get accurate flow rates when measuring fluids and gas substances. However, the knowledge of other flow measurement technologies and how they apply in various applications is paramount. This article discusses the various types of flow measuring technologies available today and how they are used in various industrial and domestic applications. If you plan to buy a flow meter, read along to find out which one will work best with your flow system. 

What are 8000XHT/XLT Flow Meters? 

These flow meters are used to measure flow rate in high temperatures and very low temperatures that other flow meters can’t withstand. XHT stands for eXtreme High Heat, whereas XLT is short for eXtreme Low Heat. They are perfect instruments for reading flow rate in liquids with temperatures between -80° C and 200° C. They are perfect flow rate measurement instruments for too high EMF environs 10V/m> 189 GHz with no LED holes and power fields of 400 amperes.

The 8000XHT/XLT flow meter sets levels that have to be done by other meters, making it a gold model for all other types of flow meters. Many people prefer this flow meter due to its great ability to work in areas with extremely low or high temperatures where other flow meters will just break down or spoil. 

Special packaging is used when handling the 8000 series flow meter depending on the environment it will work in to ensure that it gives desired results. Designers of the 8000XHT/XLT flow meter offer these types of flow meters with closed-cell foam insulators. These insulators are meant to protect operators from extreme heat or cold that this flow meter works in. The insulators prevent workers from ice-cold environs that may cause frostbites and intense heat that may inflict burns to anyone operating it. You can immerse the 8000 series flow meter into the flow and achieve the same desired outcome without damaging the instrument. 

Selecting the right type of flow meter will ensure that you are getting the best of the instrument when measuring flow rate. Failure to pick the right type of flow meter or sensor will lead to flow measurement issues that may cost you in the long run. Flow meters don’t just work differently; they are also installed, maintained, and calibrated in different ways. Therefore, the plant manager should match the right flowmeter type with the right application. 

Several considerations have been observed when selecting the right kind of flow meter. The plant manager should consider the type of liquid or gas that is being measured, installation requirements, maintenance needs, and cost. The skills needed to run a particular flower sensor are also critical when selecting one. These are just some of the basic factors used to guide the plant manager on how to select flowmeters properly.

Many operators make a common mistake of choosing the wrong type of flow meter just because it is cheaper. In the long run, wrong types of flow meters end up causing issues such as inaccuracies, constant breakage, high cost of maintenance, and wastage due to leaks. Understanding how different flow meters work is the first step of making the right choice when selecting a flow measurement instrument. 

Choosing Proper Flow Measurement Instruments 

  • Flow Rate Requirements 

Flow rate requirement plays an important role when you want to select a flow meter. You need to make a clear distinction of whether the flow rate needs to be continuous or totalized. It is also crucial to know whether the flow rate information is required locally or remotely. The transmission method also needs to be considered. There are three types of transmissions, including digital, shared, or analog. 

  • Fluid and Flow Characteristics

The fluid flow characteristics also play a crucial role when selecting the kind of flow meter you want to use in your application. Some of the aspects that make up fluid characteristics include conductivity, density, pressure, temperature, viscosity, and more. Other aspects that make up a fluid’s characteristics are fluid safety and toxicity. You should also consider these factors before purchasing because one of the flow meters can be quite expensive. The plant manager needs to access data about the fluid’s composition and presence of bubbles. 

  • Pressure and Temperature Ranges of the Fluid 

Before setting off to buy a flow sensor, the plant manager needs to know the minimum and maximum temperature and pressure values needed. You are also well informed of the fluid’s ability to develop slug, whether it can reverse, aeration, and pulsation. It should also be established whether sudden fluid temperature changes are expected. The user should also know if precautions are taken when cleaning or performing maintenance in the flow meter. This is to avoid injuries that may come from the cleaning or maintenance process. 

Different Types of Flow Measurement Instruments 

We have discussed in detail the various factors that have to be considered when selecting a flow meter. We’ll now head straight to the various types of flow meters available in the market and how they work. 

  • Mechanical Flow Meter Types 

Many fluid production and processes industries use mechanical types of flow meters to measure flow rate. Installing and maintaining mechanical flow meters is easy, not costly, making them cost-effective compared to other types of flow meters. Mechanical flow meters have moving parts inside, which can either be paddlewheels, propellers, or shunts. These components are rotated by the fluid running through the pipe. The flow rate is measured by the speed of the fluid running through the flow meter. 

Since the speed of the fluid is used to determine the flow rate, it is proportional to the volumetric flow rate of the fluid. The drawback of using mechanical flow meters is their high sensitivity. Since they have moving parts, if used with dirty fluids, they may get clogged. The best thing to do is use them with clean fluids. Mechanical flow meters incur high maintenance costs because they have to be maintained regularly to function accurately. When pressure is too low, mechanical flow meters cannot function well. 

  • Vortex Flow Meter Types 

Vortex flow meters measure flow rate through vortices shed from the sensor. They are usually used to measure the flow rate in water. These types of flow sensors are immersed into the flow when measuring flow rate. Pipes are hardly used with these types of flow meters. They are ideal options for measuring water in an open channel or non-streamlined flows such as streams, rivers, and wells. These flow meters work by measuring swirls or vortices produced by fluids when they pass through an obstruction. 

Vortex flow meters consist of sensors that capture the frequency output that is created by the vortices formed. To get the fluid’s flow rate, you need to get the frequency output directly proportional to the flow rate. An advanced kind of flow meter is available that measures various variables called a multivariable vortex flow meter. This type of flow meter uses one process connection to measure five process variables: mass flow, temperature, pressure, density, and volumetric flow. 

  • Magnetic Flow Meter

When using a magnetic flow meter to get the flow rate of fluids, the magnetic field generated from the speed of the flowing fluid is measured. This is the fluid that passes through the pipe or the flow meter. The principle used to establish flow rate in this type of flow meter is known as the Faraday Law of Electromagnetic Induction. A charge is created by the fluid flowing through the flow meter. This voltage is directly proportional to the flow rate of the flowing water. The setback of this flow meter is that it is only used to measure conductive fluids with ions. You can’t use it to measure pure water since it doesn’t have ions in it. Electromagnetic water flow meters are used in many applications, provided the fluid measured can conduct electricity. 


The flow measurement industry is full of instruments used to measure different fluids and gases. It is, therefore, necessary to know which type of flow sensor is suitable for your application. Flow measurement plays an important role in ensuring the fluids used or produced in flow systems are up to the task. 

Using the right flow meter also increases accuracy, which is crucial in applications that produce products meant for human consumption, such as medicines, food, and beverages. The service cost is also reduced when the right type of flow meter is matched with the right application. Installation of flow meters also has to be done properly so that it functions properly. If you are not sure which flow meter goes with your application, it is advisable to ask the manufacturer to help you make the right choice to avoid unwanted expenses in the long run.

It is also ideal for researching first for the best and reputable flow meter vendor who will supply you with certified and high-quality flow measurement instruments. You will have an easy time operating your flow system without worrying about breakages, wastage, and endless expenses from poor quality flow rate measuring devices.
